HI Steve,

MIDI port:
Long ago I had this "CC# sweep causing zipper noise" issue with an RME
Multiface audio interface when using the RME's MIDI ports. I found a
solution in not using the MIDI ports on the Audio Interface but a
cheap MIDI-to-USB cable/converter instead.

Badly coded plugin:
Recently I've also had "CC# sweep causing zipper noise" issues related
to the SoundToys plugin EchoBoy. I talked to the developers about that
and had it confirmed that they know about the issue (but fixing it is
not their highest priority). When the plugin caused noise I was
controlling three of EchoBoy's parameters simultaneously from the same
CC# swept by the expression pedal. I fixed this issue by only
controlling one continuous parameter in EchoBoy and directing the
signal through two other plugins/mixer stages where I applied the same
exp pedal CC# to affect the other two aspects of the live morphing

The audio interface I use now, RME Fireface400, is flawless with no
issues. Only convenience is the reason I plug everything in by USB
cables into a USB hub on the MBP - the 400's MIDI interface doesn't
have the issues of the earlier Multiface.
