i've been doing this for a while, and i assumed that it was common knowledge, but it seems that most people haven't heard about it. the 1600 and 1600x can send channel after-touch messages by programming the string: Dn pr as always, 'n' is the channel number. send a single byte, with a range of 0-127. ---this comes in handy with synths that can't be set up to receieve on any controller you want, but can receive channel after-touch. (the matrix-6 comes to mind) hope y'all find this useful... ...atom atom@suspicious.org
