Well guys,

2nd subject here.

How do I record sysex data to the XL-7?

a.
I love to do filter sweeps on my external gear using sysex. Can I 
enable the XL-7 to record SysEx data (haven't really gotten it to 
work with SysEx yet) and have it played back in the pattern?

b. 
Can I do a SysEx dump from external synths to the XL-7? (and record 
that and put it in front of a song or in an apart pattern to get my 
sounds and arrangement dumps back easily)

Thank you :)
best regards, roel
