Fifo Overflow

mjsyts

Hi Forum,

I'm running into the midi fifo overflow in both extended and vanilla and am wondering if anyone has been able to make any progress getting around this bug.

I've turned the MIDI clock function in my keyboard off, as well as tried MIDI Patchbay to see if I could filter out messages, but it isn't making a difference.

I've seen several related threads on the issue, but can't find any solutions in them. I've tried delete/reinstall as well.

I'm probably overlooking something simple here, but I feel like I've tried everything I can think of.

My setup:
Pd extended
Macbook Pro '16
Yamaha PSR-E323
M-Audio Uno Interface

Thanks in advance,
JS

Whoops! Missed this post, just found it by accident. Don't know if the OP gave up but might as well respond for the archive and mention that I finally filed a bug on this issue.

The known problem here -- as I have stated in other threads -- is probably not a midi clock issue but Active Sense messages (the Yamaha PSR-E323 midi implementation chart indicates that these are implemented in that device). Active Sense is part of the System Realtime group of commands in the midi spec (also includes clock, stop, start, and continue).

If configured correctly, Midi Patchbay on the MAC will stop these messages, but it can only be configured to block the entire System Realtime group. If the other messages are needed, a more selective option might be Midi Pipe, thou I have not yet tested this. It can be downloaded from here:
