This is odd, I was just reading through some threads in the list
archives describing this very problem.
I think the idea was floated of adding this function to massign, but I
don't know if it ever happened.
Alternatively it is possible to use the event and kschedwhen opcodes
to redirect the midi notes.

hi lars -

as you said, you can turn on any number of instruments from the  
instrument which is triggered by midi, via event_i.
because you can get the control cycle where the instrument is turned  
off, via release, you can turn off the subinstruments.
i made an example with negative p3 for switch on, and negative p1 for  
switch off. it should also work with the turnoff2 opcode.

best regards -

	joachim

very nice. so this could be a way to do it with a UDO, and a function  
table containing the instrument numbers you want to trigger:



-Ma


sr = 44100
ksmps = 32
nchnls = 1
0dbfs = 1

           massign   0, 1; assign all incoming midi to instr 1
giInstrs  ftgen     0, 0, -5, -2, 2, 3, 4, 10, 100; instruments to be  
triggered

   opcode MidiTrig, 0, io
;triggers the first inum instruments in the function table ifn by a  
midi event, with fractional numbers containing channel and note number  
information
ifn, inum  xin; if inum=0 or not given, all instrument numbers in ifn  
are triggered
inum      =         (inum == 0 ? ftlen(ifn) : inum)
inote     notnum
ichn      midichn
iturnon   =         0
turnon:
iinstrnum tab_i     iturnon, ifn
  if iinstrnum > 0 then
ifracnum  =         iinstrnum + ichn/100 + inote/100000
           event_i   "i", ifracnum, 0, -1
  endif
           loop_lt   iturnon, 1, inum, turnon
kend      release
  if kend == 1 then
kturnoff  =         0
turnoff:
kinstrnum tab       kturnoff, ifn
   if kinstrnum > 0 then
kfracnum  =         kinstrnum + ichn/100 + inote/100000
           event     "i", -kfracnum, 0, 1
           loop_lt   kturnoff, 1, inum, turnoff
   endif
  endif
   endop

   instr 1; global midi instrument
           MidiTrig  giInstrs, 2; triggers the first two instruments  
in the giInstrs table
   endin

   instr 2
ichn      =         int(frac(p1)*100)
inote     =         round(frac(frac(p1)*100)*1000)
           prints    "instr %f: ichn = %f, inote = %f%n", p1, ichn,  
inote
           printks   "instr %f playing!%n", 1, p1
   endin

   instr 3
ichn      =         int(frac(p1)*100)
inote     =         round(frac(frac(p1)*100)*1000)
           prints    "instr %f: ichn = %f, inote = %f%n", p1, ichn,  
inote
           printks   "instr %f playing!%n", 1, p1
   endin

( i was referring to victor's fractional instrument numbers - didn't  
read richard's mail before)
