other typical rack switching, and never had a delay problem. It's
possible I didn't notice, since I mostly use the dedicated pedal for the
plex, but if the PMC-10 caused a delay it must have been pretty small.
And preset switches are very quick. Are you sure it's not misjudgement
of the throw distance to the contact point of the pedal? That can throw
you sometimes if you're not used to the pedal."

 To which Mike responded with:"Well, I'm a little hesitant to take a
hard poke at the ol' PMC-10 due to my concern that it might croak on me!
That is possibly my main problem with the lag situation. I'm waaaay into
my dedicated FS5U's though. (ah, finally I remember the correct number!)
I can really mash those babies!

And then Chuck Zewicky chimed in with:"I use a Rolls 'MIDI Wizard' with
my Jam-Man setup, which in it's default state does send 8 channels of
controller data with each program change.  This does cause some lag, but
was easily corrected by de-assigning the controllers. I've experienced
no oddness or switching delays since.  Perhaps this is something to look
for."

Dear Mike,

As I am not aware of there being a lag in response when using MIDI
commands and the JAMMAN and since Kim has good experiences with his
PMC-10 I would suspect one of three things:1.) as Chuck has suggested
the PMC-10 may be trying to do to many things at once thus slowing it
down.  2.) there is a problem with the PMC-10.  3.) there is a problem
with JAMMAN.

I would suggest that you try another MIDI controller with the JAMMAN or
another device that uses MIDI program change messages with the footpedal
and see in which direction the problem follows.  Since you are enjoying
the use of the JAMMAN with your FS5Us this may not be necessary.

Please let me know if you have any questions or if there is anything
that I can do for you.
