I use my JV-1010 with computer software...
but I have no idea what the system exclusive messages are for "Roland's" typical reverbs...
(for use with my JV-1010 - I always use it in performance mode)
e.g. Room 1,Room 2,Stage 1,Stage 2,Hall 1, Hall 2, Delay, Pan-Delay.
could anyone tell me where I could get these messages...or what these messages are...? Thank you for your time.

(p.s. in the back of the manual is this message...
Offset Address 00 28
Size 0000 0aaa,
but I'm after the messages that start with
F0 and end with F7)
thanks again
