Hello.
Update your repository to the latest version, just in case.
Type aconnect -l in console and paste the response here.
Try to run visualizer.py and this time copy and paste whole console output.

from piano-led-visualizer.

aconnect -l give's me the following response when i run sudo btmidi-server -v -n "RPi Bluetooth" in another terminal.

1. pi@raspberrypi:~ $ aconnect -l
2. client 0: 'System' [type=kernel]
3.     0 'Timer           '
4.     1 'Announce        '
5. client 14: 'Midi Through' [type=kernel]
6.     0 'Midi Through Port-0'
7. client 128: 'RPi Bluetooth' [type=user,pid=1943]
8.     0 'RPi Bluetooth   '

and this response when i am just connected with my laptop

1. pi@raspberrypi:~ $ aconnect -l
2. client 0: 'System' [type=kernel]
3.     0 'Timer           '
4.     1 'Announce        '
5. client 14: 'Midi Through' [type=kernel]
6.     0 'Midi Through Port-0'

This is the whole output when trying to run visualizer

So you don't have connected keyboard to RPI, right? I will make an exception so it won't crash when there is no input set.

from piano-led-visualizer.

I dont have a piano midi keyboard connected to my rpi.

I do have a computer keyboard connected

from piano-led-visualizer.

By default it tries to set keyboard as input, if you want to set your PC as input you have to run visualizer.py and then change input in menu. I just made an update, download new version.

Thanks!
When i run the updated version, there is no output/response. Nothing happends

from piano-led-visualizer.

Yes, because there are no ports set yet.
Go to "Ports Settings" -> "Refresh ports"
and then to "Input" and choose RPI-Bluetooth.
Now the keys should light up when you play midi files with Synthesia (if you configured everything correctly in Synthesia)

I mean when i try to run the updated version.

1. pi@raspberrypi:~/Downloads/Piano-LED-Visualizer-master $ sudo -E python visualizer.py

What exactly you are trying to achieve? You don't have a keyboard connected to RPI so I guess you want to light up LEDs with Synthesia, right?

from piano-led-visualizer.

Yes, i want to play a midi file on my laptop on synthesia, send the midi data over bluetooth to rpi and light up LEDS.

from piano-led-visualizer.

Do you have screen on your RPI? If yes then refresh the ports and then set RPI-Bluetooth as input. Then it should work. This is how it looks when I disconnected the keyboard to recreate your setup: https://gfycat.com/pl/shockedcarefreebighornedsheep

from piano-led-visualizer.

Ah, i dont have the small LCD screen, instead i have a 27 inch HDMI screen connected to it :) can i use that?

from piano-led-visualizer.

No, I'm afraid you will have to edit the visualizer.py :D
Replace line 665 in latest version with
if "RPi" in port:
It will set RPI-Bluetooth device as input.

Thanks a lot, that works!
I also have a midi cable connection. I can see that the bluetooth midi data is not as steady as the midi cable. All the data is correct, but there is a delay of +-half a second sometimes.
