rotary encoders about control-surface HOT 21 CLOSED

Hi,
The RotaryEncoder class has been renamed to CCRotaryEncoder.
The interface has been changed as well, you can find the documentation for it here:
https://tttapa.github.io/Control-Surface/Doc/Doxygen/d3/d62/classCCRotaryEncoder.html

My apologies for the lack of proper examples or better documentation, the library has gotten really huge, and I have to find ways to combine working on it with my studies.

I'm in Belgium, it's 11:11 am here, no worries :)

from control-surface.

i have tried everything to get the rotary encoder working with no luck

either i have the incorrect encoder.H library or i am writing the code incorrect to create a new instance of CCRotaryEncoder

any help with an example would be greatly appreciated

also in the MCU protocol what midi message is it sending out for the VU meters

im hoping i can just send the midi data from cubase (which i can set the type of midi message on) to the controller and get the vu on a shift register working

from control-surface.

I added a rotary encoder example: https://tttapa.github.io/Control-Surface/Doc/Doxygen/d3/d15/CCRotaryEncoder_8ino-example.html

also in the MCU protocol what midi message is it sending out for the VU meters

It uses MIDI Channel Pressure events: the high nibble of the data byte is the track (0-7) and the low nibble is the value (0x0-0xC) or clear overload (0xF) or set overload (0xE). 0xD has no meaning.

ok looking at the code you have put up it i would have to use the mcu mapping
is there any way for me to set specific channels and addresses like we could before?
so i can use the generic mapping in cubase

RotaryEncoder encoder(2, 3, 0x14, 1, speedMultiply, NORMAL_ENCODER, TWOS_COMPLEMENT);// comes through as a controller on channel 1,address 20

or has this all changed?

i.e.

CCRotaryEncoder enc ={
{2, 3},
MIDI_CC::Pan, CHANNEL_1,
1,
4,
};

The Reason for me to do this is i can do alot more through the generic program function in cubase
even create banks and flip modes

from control-surface.

this code below works

CCRotaryEncoder enc ={
{2, 3},
MIDI_CC::Pan,
1,
4,
};

it functions well and comes though to cubase on Channel 1 address 10

but i cant change channel number

from control-surface.

You have to add curly braces, the address is a single parameter:

CCRotaryEncoder enc ={
  {2, 3},
  {MIDI_CC::Pan, CHANNEL_1},
  1,
  4,
};

from control-surface.

Using the generic controller function is also why i was asking about the vu meters

when i set it to a Mackie controller in cubase my Vu meter works
but i cant set a specific channel and address in the code to use with the generic controller

from control-surface.

Ok that makes sense
it compiles now

you are an awesome dude

How did you go with finding some Arduino Nano Boards to test out your faders????

Could you check what kinds of messages Cubase sends? The easiest way is to use a MIDI monitor on you computer, alternatively, enable debugging information in Settings.hpp: uncomment lines 17 and 19.

I started working on it, but I don't have the right hardware here right now.

from control-surface.

Can you suggest a MIDI monitor to try

i have midi ox installed but it wont get anything from cubase

Feel free to Face time me on [email protected] so you can see it all

from control-surface.

I use MIDI Snoop on Linux, but any monitor that runs on your platform should work.

Edit: it seems that the MIDISnoop domain has expired, and is now just spam. It's still in the repositories though: https://packages.ubuntu.com/bionic/sound/midisnoop

from control-surface.

hmmmmm i tried the debug but it wouldnt compile and just had errors

and for some reason the midi monitor wont connect when cubase is running

from control-surface.

Did you pull the latest version of the library?

from control-surface.

yep yesterday

from control-surface.

I pushed another change this morning, that should have fixed the debug issues.

Did you install the library using git? https://tttapa.github.io/Control-Surface/Doc/Doxygen/d4/d6d/md_Installation.html
In that case, you can just do git pull to update to the latest version.

from control-surface.

i have just downloaded the new version
it compiles
and i have put the USBDebugMIDI_Interface into the code but it doesnt seem to do anything
still works as a controller though

i might have to give up for the night,
have good day pete

Here is what i have so far

Keep the USBMIDI_Interface, don't use the debug interface, just enable debugging in Settings.hpp, see the link in a previous reply: #13 (comment)

Then open the Serial monitor and check the incoming messages (prefixed with >>>).

from control-surface.

all good close this issue if you want as the encoder is working well
i will start a new one for debugging
