RE: JamMan ROM upgrades?

Hi John,

The latest software for JAMMAN is V1.01.  I am not aware of it addressing  
the problem that you have described.  If you open the machine up the ROM   
with the part # 350-09278 will either read V1.00 or V1.01.  If you have a  
V1.00 ROM a new ROM can be purchased for US$18.53 plus shipping and   

Some MIDI products use numbers 1-128 and some use 0-127. These are the   
same messages with the numbers offset by 1.

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

Best regards,

Subject:  JamMan ROM upgrades?


I recently picked up a used JamMan, and I find that the triggering is
very 'spongey' from both the footpedal or from MIDI (the Tap button
doesn't seem to have this problem).

A friend who does studio engineering says he remembers getting a ROM
upgrade that took care of this problem, but I didn't see any reference
to the on Loopers Delight pages.  Can anyone confirm this?

Also, the MIDI program change numbers seem to be off by one from what
the manual says ('Tap' seems to respond to Program 0, not 1, and so
forth).  Is this a JamMan glitch or a Vision error or what?
