Thanks so much for your reply. I highly respect your knowledge on matters of Mac and Logic, in fact, it is your recommendations that led me to purchase the set-up I presently use. Upon pulling up the event list for the organ track, I am not real sure where that info is listed. I fixed the problem by going into the track automation, and selecting the B-3/rotor cab./speed control, then selected the automation mode to latch. This allowed me to see and record the mod wheel's movements and parameters. In my opinion, a pretty convoluted way of doing things, especially when the mod wheel is configured to control the leslie speed, and does so audibly and visually. To answer your question, I assigned the rotor speed control through the smart control window learn phase. Thanks again
Mr.Art, keep on doin' what you do..............S
