Re: trouble sending sysex

2005-09-27 by eriksatie01

the fact is that my evolution keyboard (that is also my midi 
interface) only has a midi out, so I cannot record midi flow on my 
computer, and I cannot do some usefull test like dump sysex from my 
xl-7 to pc and back. 
but I still have several things to check. hope this evening I will 
find some time to try.
surely I will keep you informed about it!
thx
