On windows 10, FluidPatcher 0.7.15 isn't installing python modules properly. FluidPatcher 0.7.14 looks doing it well.

Hi, thanks for your work, it's an awesome project.

I'm trying to get the install working for a raspberry pi and have run the install script from https://geekfunklabs.com/squishbox as per the instructions on a fresh raspberry pi os install.
I plug a USB MIDI controller in and turn it on, it initialises OK, I see the 5 lights flicker and then it starts to make sound. Which is awesome :)

Having a bit of trouble with notes that are played after a short break. If I don't touch the MIDI keyboard for more than ~15 seconds it will be slow to start making sounds again. It typically makes sounds after a couple seconds of hitting notes, but I've had it not play any single notes and only start making sounds when I make chords.

I've reproduced this behaviour with 2 MIDI keyboards (M-Audio ES61 and Akai LPK25) and have included links to videos of what I mean. It seems a bit less sluggish on the Akai keyboard, although it still shows the behaviour.

MAudio 61ES
Akai LPK25
Akai LPK25 waiting a minute and then playing again

I'm hoping to use this as a sound module at a gig, and will be switching between playing keyboard and guitar, so i'm hoping there's a bit of config somewhere that can fix this.

I've had a look at the fluidpatcher code and couldn't see anything obviously that would introduce this delay, but I haven't read much python for a while so might have missed something.

Are there any more debugging/troubleshooting things I could do to figure out whether the delay can be removed?

Hi, first, thanks for you work on this. (En is not my native language, sorry in advance)
I've found/feel that the "real" latency is much less noticeable using jack as an audio driver than alsa.
Thing is that using jack won't autostart fluidsynth on boot.
It's possible?
Secondary question:
I'm unable to effectively modify the period one ./jackrc; (or whatever i do on fluidsettings.xml)
"fluidsynth warning requested a period size of 64 got 444 instead" but i'll keep tinkering this,

Thanks!

Describe the bug
I'm running on a Raspberry Pi 3B with a Keystep 37. Notes can make it into the Pi, and notes can make it out separately from midi files, but I can't get the notes playing to produce any sound.

Notes show up with aseqdump, e.g.:

pi@keystep:~ $ aseqdump -p 20
Waiting for data. Press Ctrl+C to end.
Source  Event                  Ch  Data
 20:0   Note on                 7, note 71, velocity 80
 20:0   Note off                7, note 71, velocity 64

And if I run a command like the following, I hear audio from the connected headphone jack:

fluidsynth -a alsa -o audio.alsa.device=plughw:0,0 -n -i /usr/share/sounds/sf2/FluidR3_GM.sf2 SquishBox/midi/elevatorgroove.mid

Because I had to add that -o flag, and because of the output from aplay -l, I have edited my fluidsettings to include audio.alsa.device: 'plughw:0,0'.

pi@keystep:~ $ aplay -l

If I add a few print statements, I can see the listener from headlesspi.py firing for notes, but I don't see send_event functions elsewhere getting called.

Output of headlesspi.py (the thread priority messages go away if I run with sudo):

Any ideas what I could try next?

Background Info

• I am trying to run the program via headlesspi.py.
• Running on Raspberry Pi 3B with Debian GNU/Linux 12 (bookworm)
• FluidSynth version 2.3.1

No matter what I do, doesn't work for me. I did copy the router_rules section from bank1.yaml that works for me, and the init section on the bottom, i did put the proper filename into squishboxconf.yaml (currentbank: fluid_gmbank.yaml), paths are unchanged, yet upon reboot it just doesn't play. The file looks like this and produces no sound at all at any channel or patch number:

router_rules:
  - {type: cc, chan: 1=2-16, par1: 7}
  - {type: cc, chan: 1=2-6, par1: 1}
  - {type: cc, chan: 1=2-6, par1: 64}
  - {type: cc, chan: 1=2-6, par1: 91}
  - {type: pbend, chan: 1=2-6}

I don't see any functional difference to the default bank#.yaml files, yet those play and this doesn't. Permissions are the same. Any clues?

Hi Albedozero, how are you

Thank you for this wrapper, I'm currently adapting it for a performance with an early music ensemble. I intend to emulate pipe organ stops, but I wonder what it would be the best way to do so. I'm trying to avoid assigning volume = 0 for a particular channel. Instead, I would like to turn on/off a given program by routing/unrouting channel 1 to the channel assigned in the bank file for the preset. The behavior should be like turning on and off a particular preset.
Is there a way to unroute a previously routed channel? Do I Need to extend fswrap.py to add a function to wrap fluidsynth's api call 'delete_fluid_midi_router_rule'? In that case: how do I refer to the id of an existing rule?

Thank you very much for the advice

Hello,
actual version of bank0 seems to have an error in the Elevator jam preset. Each time I switch to it by running headlesspi.py in a SSH session the output is:

Hi,

I thought it would be easier to use GitHub because I have an account. I have not had time to look at the Raspberry Pi since writing this because of work and having to fix/move a website for a friend that has taken lots of my spare time.

The one thing I have done is order a Pi Sound sound card by Blokas that I am waiting to arrive which I am hoping will be better than the on board sound and the cheap USB interface I bought.

Let me know if you have an idea of what I can test because I have not really got my head round how audio and midi works under Linux because I come from a Windows background.

Thanks for your help!

Tim

Here's where we are from the youtube comments:

Just trying the setup now but I don't get any sound when I plug in the midi controller (Launchpad Pro Mk3). How do I debug because I am very new to audio on a Raspberry Pi.

Are you certain you're sending note messages from the Launchpad? The default initial MIDI Mapping on the Mk3 only sends CC (continuous controller) messages - Custom 3 and Custom 4 look like they send some notes. To do some debugging, you can log in to your Pi via ssh (see https://www.raspberrypi.org/documentation/remote-access/ssh/ for how) and type:

sudo systemctl stop squishbox.service
python3 headlesspi.py

This will give you some feedback on when the script changes patches, banks, etc. You can also type aseqdump -p 20:0 to see what MIDI messages your controller is sending (if your controller is not on port 20:0 type aconnect -i to see what it is).
Feel free to reply or post in the forum at https://geekfunklabs.com/forums/forum/questions-issues/ if you have more questions!

@the White Tornado Just had a look at the forum and don't see a way to register to ask a question. I have run the scripts and I can see the launchpad as device 24 and there are note on and off messages. I have tried changing the channel for the midi notes but nothing happens. What's the next step to test?

Try rebooting the Pi (so the script is running) and log in via ssh again and type aconnect -iol - this will let you see if the Launchpad is connecting to FluidSynth. Also, see if your audio output is working by typing speaker-test.

Karhide

@the White Tornado It looks like it is connected because the launchpad is 24 (see below) and if I run the speaker test I hear white noise. Is it because the launchpad shows up as multiple items?

Thanks - good to know sound is working and the Launchpad is connecting. It's a bit surprising that the Launchpad presents 3 MIDI devices to read from, but it shouldn't matter - you can connect as many MIDI controllers as you want to FluidSynth and it will read from all of them. I think this must be something to do with the messages the Launchpad is sending. I do notice that the one note on message I can see has a very low volume, so it could be working but the sounds are just quiet. It might also be sending some conflicting messages (like note offs or CC7=0) on the other ports - try aseqdump -p 24:1 and aseqdump -p 24:2. If you have another MIDI controller lying around, try connecting that and see if you get sounds, so you can at least narrow it down to a problem with the Launchpad.

@the White Tornado Just had chance to hook it all up again and I can see note on messages with a velocity of 124 but still no sound. I don't have another midi interface with me other than the Novation Circuit Tracks that seems to show no difference. I do have a midi interface that has 2 ins and 2 outs and I have plugged the launchpad directly in to that and it is just the same. Any ideas or is it time to give up?

Karhide

My idea would be to use the Fluid synth on headless pi as a sound source for the Circuit Tracks sequencer and I think it'd make a really cool and portable system.

Just done some more digging and reinstalled using the script and then ran fluidsynth and got the following:

So looks like it could be an issue loading the soundfont. I will dig a bit more.

Hi @Karhide - you can ignore the 'unable to load default.sf2' message - the FluidSynth team added an option to load a default soundfont on startup, but our script loads its own soundfonts as specified in SquishBox/banks/bank1.yaml. Not sure why you're still not getting sound - maybe we could hop into discord so we can back-and-forth a bit more easily. I'm on a trip at the moment but will be available in a week.

I have a problem with the pi crashing when I change patches. Today it at least went to 3 other patches before crashing. I'm running the latest Ubuntu desktop on pi 3b+.
I'm a total novice to working with a raspberry pi, only got it last Saturday but am excited to learn python.  @the White Tornado  Ok so I booted up, the piano soundfont voiced when I played the midi keyboard, I entered the command you provided in terminal. The following messages appeared and the sound stopped. "Failed to stop python3.service: Unit python3.service not loaded.
"Failed to stop squishbox.py.service: Unit squishbox.py.service not loaded. Usually when it's headless the pi just crashes as soon as I load a new track. I tried last night on my NI KKm32, and nektar lx49+. The Nektar I pressed every button to change patch with no luck. The M32, one of the encoders changes cc settings, and this is when the pi crashes. Thanks for taking the time to help me get this sorted.

For the specific pip error message I've logged this on stackoverflow.

Steps to reproduce:

1. installed the latest x64 exe installer from https://github.com/albedozero/fluidpatcher/releases/tag/v0.7.15

• Python was already installed before.

2. Start the desktop shortcut FluidPatcher (corresponds to pyw).

Expected result:

• FluidPatcher starts.
• In addition, installer should catch error when Python pip installation fails. Now it completes.

Actual result:

• FluidPatcher doesn't start, no error message.

##Troubleshooting:

Re-ran the installer and isolated the issue to the following installer step:

Succeeds:

Execute: py -3.10-64 -m pip install -U oyaml

Succeeds:

Execute: py -3.10-64 -m pip install -U mido

Execute: py -3.10-64 -m pip install -U wxpython
Execute: py -3.10-64 -m pip install -U --pre -f https://wxpython.org/Phoenix/snapshot-builds/ wxpython

Re-ran pip commands:

For oyaml, mido: succeeds

py -3.10-64 -m pip install -U mido

Hi,
I recently put together the v3 version of the sqiushbox with the pcb. (Litterally the day before v4 was released! aghhhhhhh! I might have to upgrade later, but I wanna get this one working first)
Anyways, I installed the firmware onto the raspberry pi and went through the setup, but I'm getting neither a sound output or text on the lcd.
I can confirm that the lcd works and it is reciving power, I also tested all the wire paths for continuity and they are fine. Perhaps its an issue with the pi's gpio?
I'm an Arduino guy so any help would be greatly appreciated and I will gladly provide more information/details if anyone can help me.

On Squishbox 0.8.4 (v4 hardware),
when I want to add new patch and I want to save it, i see the following error: name 'mode' is not defined and Squishbox doesn't save the patch.

To add the new patch I select open soundfont, then I select the soundfont I want to add and I click on the two button to see the check mark (is the only way I found to see the check mark to save the patch). At this time I see the error.

Can you help me?

First - thanks! The Squishbox works like a champ (may send notes of some minor issues, but for now, gr8) I'd just set up a raspberry with similar functionality, but your little box brings a much nicer physical interface to the metaphorical table.

Secondly - noticed you used the ubiquitous FluidR3_GM.sf2 sound font... there's an example at:

https://gist.github.com/albedozero/721442c1d112839c71fd8f7d9ce1a98b

It runs through the full number (close to 200 different instruments)... if you simply put the file (any reasonable file name ending in .yaml seems to work) in "SquishBox/banks", your basic "router_rules" at the top of the file, it works like a champ. You might consider putting it as one of your sample bank files, but of course YMMV... scrolling through even 200 patches doesn't take that long, and it's all the more impressive when kicking the tires of the squishbox.

You may have this somewhere in your notes/dox, but I didn't see it.

Tnx again!

Hi, I'm not able to update squishbox to 0.7.11 version from 0.7.9 from software option.

Hi there,

Running Python 3.5.3 on Raspian "Stretch"

I get this error when running headlesspi.py:

ImportError: cannot import name 'time_ns'

Traceback:

File "headlesspi.py", line 10, in <module>
from utils import netlink

Hi,

I tried following the install instructions, mainly to put fluidpatcher on my Ubuntu focal 20.04 desktop so that I can try to push patches to my Pi running the synth software.
sudo apt install libfluidsynth

I get the error:
E: Unable to locate package libfluidsynth

I notice libfluidsynth2 is available for my distribution but once I try to open the patcher python starts coughing up errors.

Describe the bug
The script squishbox-install.bash no longer works as is because the Github account has changed name from albedozero to GeekFunkLabs and the script still references albedozero.

Workaround
A workaround is to download the script and edit it replacing all references to albedozero with GeekFunkLabs then run it locally.

Hi,

Im sorry to be a thorn in your side. Thank you for sending the build kit over, Im really looking forward to getting it operational.
I have connected it all together and have a bit of troubleshooting to go through.

Firstly, I went through the install instructions as per your website. When I ran the script:

curl -L git.io/squishbox | bash

I noticed some errors during the running of it. The first thing I noticed is that php7.4 was installed with RaspberryPi OS. I downloaded your script code and changed every instance of php7.3 -> php7.4. It then ran without errors.

I choose the audio interface no 3.

Unfortunately Im getting no characters appear on the screen. It is getting power.
I have tried adjusting the contrast with a screwdriver but there are no characters output on the screen.

When I run ./squishbox.py from the command line, I get the following:

Do you have any ideas on how I might troubleshoot this?

Thank you for your time.

I need to be able to change the current patch up and down using two notes (e.g. A1 and B1) on headless.py but my keyboard doesn't have any controllers.
Is there any way to achieve this, either through router_rules or the API?

Thanks for an excellent project!

Hi there,
It looks like there's a small bug in the installer at https://geekfunklabs.com/squishbox

The line apt_pkg_install "python3-rtmidi" gives a "failed to install error.

Changing it to: pip_install "python-rtmidi" seems to work. (note the removal of the 3 as well as the change to pip.

I haven't yet finished the full install, but that change gets me past the error.

Thanks,
Mark

In your installer (https://raw.githubusercontent.com/albedozero/fluidpatcher/master/assets/squishbox-install.bash), where you tell people to -

curl -L git.io/squishbox | bash

The script does:

fmgr_hash=`wget -qO - geekfunklabs.com/passhash.php?password=$password`

You really should do this on the raspberry pi itself vs. over the network. An unscrupulous person (if not you, someone could grab the domain or do MitM since you're not using https in the command) could save the password along with the requesting IP and potentially do some harm to someone installing the package (either by directly accessing the pi or by abusing people who use the same password all over the place (... it happens....)

E.g. It'd be easy to do something like (or w/e) -

php -r 'print password_hash('"$password"', PASSWORD_DEFAULT);'

Hi there,

This failed in the 'upgrade system' path, and also when re-running the curl but choosing not to upgrade the system.

I tried manually installing rt-midi, but it's not working.

Hi,

I notice when playing 'Analog Pad' or other pad style presets, perhaps using too many fingers, ie pressing too many keys, the Pi will cut out. I thought the Pi 3B+ should be enough to handle that amount of throughput (or am I looking at this the wrong way).

Is there a way to limit the polyphony on certain presents to prevent this from happening?

From running htop, I notice that python3 /home/pi/squishbox.py is running two or three times. I presume this is some funky coding techniques.

When I run squishbox.py from the command line I get:

I notice you use jackd1 as the audio server in the background. Apparently the multithreading in jackd2 is much improved.
Unfa gives a short explanation of the issue \ features of both here (Ive jumped it to the appropriate section of the video)

Hi!

Thank you for making Fluidpatcher I really enjoy working with it! I did notice one issue recently.
I have a midi controller (nanoKey) that send System excusive messages when I switch scenes.

Example of such message - selecting first track:
"System exclusive F0 42 40 00 01 36 02 00 00 4F 00 F7"

xdotool catches this but MIDI monitor from Fluidpatcher doesn't show these messages at all. I tried using the CLI version and MIDI monitor there gives an exception:

Exception ignored on calling ctypes callback function: <function Synth.__init__.<locals>.<lambda> at 0x7f81df94e0> Traceback (most recent call last): File "/home/bane/synthsynth/fluidpatcher/pfluidsynth.py", line 573, in <lambda> self.custom_router_callback = fl_eventcallback(lambda _, e: self.custom_midi_router(e)) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/bane/synthsynth/fluidpatcher/pfluidsynth.py", line 648, in custom_midi_router self.midi_callback(MidiSignal(mevent)) File "/home/bane/synthsynth/fluidpatcher/__init__.py", line 464, in _midisignal_handler if self.midi_callback: self.midi_callback(sig) ^^^^^^^^^^^^^^^^^^^^^^^ File "/home/bane/synthsynth/fluidpatcher_cli.py", line 71, in sig_handler t = MSG_TYPES.index(sig.type) ^^^^^^^^^^^^^^^^^^^^^^^^^ ValueError: tuple.index(x): x not in tuple

Is it possible to catch these messages in midi monitor in CLI?

My goal is to have the Pi4 with Fluidsynth/Fluidpatcher permanently turned on and only having to turn on the MIDI keyboard (Nektar LX88+) to start playing.

Currently, if I disconnect/reconnect (or turn off/on) the keyboard, Fluidsynth doesn't start playing unless I manually restart the squishbox service.

midi.autoconnect is already set to "1" in squishboxconf.yaml.

What else can I do? Thanks!

BTW thanks for all your help so far!

I am using your software as is, only changed wheel and button control numbers to reflect my Lauchkey 25 MIDI KB

each time I switch to a preset that uses LADSPA Plugin, it could not be loaded. I.e. selecting patch 4/12: HohnerD6 Clav it throws

Also:

Warning: You do not have a LADSPA_PATH environment variable set. Defaulting to DEFAULT_LADSPA_PATH.
But I checked the folder /usr/lib/ladspa and all expected effect are there.
So how to fix this?

hi
i tried to install fluidpatcher with python 3.11 on win 64

wxpython ist compatible to python 3.10 so it won't run on the python 3.11
the fluidpatcher setup fails with some errormessages and can't be startet

in conclusion i can't use fluidpatcher on win 64 with python 3.11

greetings

Hi there - nice project you have here. Getting consistent crashes with headlesspi.py when changing patches using midi keyboard transport keys.

The setup I have is:

• Raspberry Pi 4 Model B Rev 1.1 with freshly installed Bullseye
• m-audio Axiom 49 Gen 1 midi keyboard connected via USB (powered via adapter).
• PiSound HAT sound card

headlesspi.py launches successfully and plays notes like a normal piano. Changing banks works fine using the midi keyboard's Play button (transport keys).

But using the keyboard's Fast Forward and Rewind buttons (transport keys) to change patches consistently causes the Pi to shutdown. See screenshot.

checked /var/log/messages & /var/log/syslog without much to see (excerpts attached)

Hello
After start install procedure with

curl -L git.io/squishbox | bash
and replying to option request, the install script fails with this error

Problems installing fluid-soundfont-gm!

I'm on a PI with Raspbian GNU/Linux 11 (bullseye)

Any help please....

I spent Thursday and Friday of last week trying to get this running on my Pi 3B v1.2, using an Akai MPKmini MkII as the controller (the very same as the one in your video, I think?).

I can get sounds to work when running headlesspi.py in Terminal. However, it opens with an error related to Sine Wave.

For reasons unclear to me (sorry if it's simply down to me not understanding some fundamentals -- tell me!), the script does not appear to run on boot, even after adding it to crontab.

I can use K5 (encoder on Akai) to move through various sounds, but cannot get a sense of whether the bank and patch change options are working (which I hooked up to Pad 8, 4, and 3). It might be useful to have Terminal spit out a print() message when changing, with some info. The pad controls appear totally erratic at present.

Anyway, please let me know how to help, and if you can, gimme some pointers on why I can't get this to work as hoped :)
