[comp.music] Emu Proteus 1 and 2 Patch Mapping

de@helios.ucsc.edu (De Clarke) (05/24/91)

I heard a rumour the other day, that there is a way to get
past the Proteus patch mapping limitation (yeah, you got
390+ patches in there, but you gotta choose only 128 to respond
to MIDI patch change instructions 0-127).  I have mapped my
Proteus-1 accordingly;  but I do rather regret those unmapped
sounds.

I plan to call Emu, but I thought I woul check here and see
if there is a secret and what it might be (a sysex message?)

There is a sysex to set the current program of the basic channel,
which is the channel currently displayed in the LCD. There is
also a sysex to set the basic channel. Between these two, you can
set the program on any channel to any program. I don't have my
manual with me, but in the back few pages are the sysex instructions.
You send a basic channel sysex to set the display to the channel
whose program you want to modify. Then you send a program number
sysex to set the appropriate program. The sysex data format is
signed 14 bit, split up into the bottom 7 bits of two successive
bytes, so you can represent any program number up to 8191.
