[PD] Throttling midi message rates

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!
