Here are the settings I got off VS-Planet:
These are for controlling a VSR with the 880ex. Just substitute "Sonar" for "VSR." You may have to play with these two...
880EX
System Prg?
SYS Master Clk=digin 1
Midi Prg?
SYS MID: MIDITHR = Out
SYS MID: SysEx.Rx = off
SYS MID: SysEx.Tx = on
SYS MID: MMC = MASTER
SYS MID: CtrLoca l= On ( to run the EX Controls==To run VSR controls w/out changing EX controls, set this to Off )
SYS MID: CtrType = Excl ( to run the VSR controls==To run the EX controls with out changing VSR controls, set this to Off )
SYS MID: P.C. Scne = On
SYS MID: P.C. Eff = On
SYS Sync/Tempo?
SYS Syn: Source = INT
SYS Syn: Gen.= MTC
SYS Syn: ErrLevel = 5
SYS Syn: MTC Type = 30
Make sure you have midi out on the 880 to midi in on your pc soundcard and vice versa. If you don't have another midi port you are SOL if you want to do midi input to Sonar at the same time.
In Sonar, select internal sync as you don't want the 880 and the PC to be "rolling" at the same time in this scenario.
In Sonar, you want to use Remote control. Right click on the control you want to automate and set it to the proper control number and midi channel. Click on learn and move the control on the VS. The control number will set automatically.
Hope this helps. Let us know.
