I am trying to control an ancient (but superb) external device (Roland VS2480). The track faders on this device responds to 'control number 39'. I cannot edit this within the VS4580. If I am going to control the device I will need to send 39 from the DM4800.....However the '24 midi mixer' and '24 user defined' options in the ' remote' control list do not allow this to be edited and then sent. The DM's cc numbers stops at 31 and restart again at 64.......I can however use the '16 midi faders' option, as this allows control change number 39 to be sent, but this limits the the Tascam to send only with the faders. I cannot use the sole, mute pan etc........Is there any solution? Any work around through the DAW perhaps. Any firmware updates that improved on this?
