Looks like this issue

I can recover the locked-up Pd by disconnecting the ALSA MIDI in the
QjackCtl Graph. (see animated gif in the github issue)
The MIDI device I'm experiencing this issue with is a Sensel Morph in
14bit MIDI mode.

PD tries to handle MIDI as fast as it gets it, hence Miller's warning.
First, does Pd lock up on the RPI *without* your patch running? If so,
then Pd itself is clogged up by all the messaging on the RPI. If it's
your patch, then your message handling can/should be optimized ala
Ingo's suggestion. Do you have any GUI objects in the message chain? If
so, the fast messaging will also be causing GUI updates which may be
slow on the RPI. Another way to check this is to run Pd with -nogui and
see if it works without hanging.

Hi,
I have an FCB 1010 MIDI foot pedal controller with 10 switches and two
pedals. One of the foot pedals is used to control glissando rate. More
specifically, it is hooked up to a vline~ object in pd. (I originally used
a line.)
If I change the pedal position too quickly, it locks up PD, and I have to
kill and restart the software. I have not encountered this before, but I
remember Miller saying something about "bad things happen" if the MIDI
input rate is too high in one of his MS171 lectures.
I do not have access to the firmware code on the foot pedal board, so I'm
hoping there is a way to throttle MIDI data rates in PD. I am running on a
raspberry pi 3 (buster) in a Zynthian kit.
Any pointers appreciated.
Thanks!
