I have recently set up enviroments in Logic to control my hardware synths. I am using Logic 5.5 because I haven't used it much in the 4 years I've owned it so I never upgraded. I have been able to find or create enviroments for most of my older synths using sysex faders, the only problem I've had so far is creating a sysex fader that sends negative numbers -63 to +63. Except now I am completely stuck when it comes to creating faders to control my prophet VS. It uses what seem like control change messages but 4 for each parameter. I have to be honest, with standard sysex strings things were pretty easy, I would just enter the numbers, set the value byte and it would work, this has me very confused because I know it's not sysex but it's not standard CC's either. Here is an example of what the manual tells me: Bn => Channel Number 62 => param select LSB XX => LSB of param (from table in back of manual) This is a static number Bn = Channel Number 63 => param select MSB XX => MSB of param ---This is static as well Bn =Channel Number 26 => data entry LSB VAL => this is the parameter value (00-07F) Bn =Channel Number 06 => data entry LSB VAL => this param is usually only 7 bits wide so the MSB is zero-- (only a couple parameters are more, 8/10/14 bits) anyway one fader needs to send all this info to control one parameter and I can't for the life of me figure out how to do it, so I am hoping that there is somebody who can instruct me. Any help is appreciated, Thanks Brian

Brian, IIRC you need to use sys-ex faders, each containing the 4 CC messages, but before you close the sys-ex fader window leave only the data entry CC(s) selected (the unselected ones won't change value when you move the fader). I haven't studied your question closely, but at first glance it seems that you might need to use the "Filter" parameter in the fader's Parameter Box to set it to 14-bit. HTH, Bill
