can you provide an example for windows and raspberry pi.
I am using loopbe1 midi and trying to send midi messages the issue that I have is
conn = MidiConnector('/dev/serial0')

its not clear what we should insert here or how to find the path

Hello,

Sorry if I am forgetting something that might resolve this issue instantly. The current problem that I am having is that I am attempting to use this library and another library called python midi (https://github.com/vishnubob/python-midi) for the same project. The issue is that both libraries utilize [import midi] to call upon the module. I considered manually going into the py-midi library and changing the label to make both libraries functional. Currently, I do not have access to any of the functionality of the py-midi library since [import midi] will only import the python midi library.

My code:

import midi
c = MidiConnector('/dev/serial0')

Output:

c = MidiConnector('/dev/serial0')
NameError: name 'MidiConnector' is not defined

I assume that that the import midi is importing the other midi module; therefore, causing the py-midi library not being imported and causing the NameError.

Thank you for your time.

So far, we need to give a Channel when building a SysEx message, even though it won't be used...

There is better to do

Using with some Midi devices and I got error when hitting play on the midi devices.
SysEx message like 11111010 [Start/Play] got halt in the while loop. Not sure what's the reason. Tried two midi devices I have. Same problem occurs.

When a timeout is used, if nothing is received when timeout expires, it still tries to create a Message, thus an exception is thrown...

Hello,
Thank you for creating this library. Are there some more examples available anywhere? I'd like to create a custom interface to my MIDI controller that detects if a certain combination of notes are sent at the same time (buttons pushed together) and then sends a different note, possibly on a different channel. The script would just be a series of "if" statements checking for different note combinations.

Hello,
I'm trying to send midi messages from a Raspberry Pi 3B + with the latest version of python.
All seems to work fine but when I made the command:
conn.write (msg)
I do not get the value of the number of bytes sent and the MIDI message is not sent.

If anyone has a solution I would be eternally grateful to him!

I found a possible bug for SysEx, and try to fix it.
In midi.py (310), instead of i message.type != SysEx :
if message.type.__class__ != SysEx :

Hope it will be usefull to someone

Specifically, adding MIDI-Capability Inquiry, Profiles and Property Exchange

Is there a way to access USB connected MIDI devices / Ports ?

I checked the /dev folder but nothing looks like my connected MIDI device.

I'm trying to use this library to send a SysEx message to my Boss GT-1 pedal.

Here's what the full message should look like (with header and footer):
F0 41 00 00 00 00 30 12 7F 00 00 01 01 7F F7 (all values in hex)

Here's my code:
`from midi import MidiConnector, SysEx, Message
conn = MidiConnector('/dev/serial1', timeout=5)

sysexCmd = SysEx(0x41, 0x00, 0x00, 0x00, 0x00, 0x30, 0x12, 0x7f, 0x00, 0x00, 0x01, 0x01, 0x7f)

msg = Message(sysexCmd)

conn.write(msg)`

I'm trying all of this on a Raspberry Pi 3, but the conn.write() method never returns and the message is never sent.
