Dear community,
I've created a score that uses 2 different instruments, created with
additive synthesis.
I would like to use the first instrument for the lower, and the second
for the higher register.
I would like to know, if and how this could be done.
Thanks for Your patience
Stefan

Dear Ian,
thanks for Your help.
But I used two instruments with additive synthesis and I don't know
how to use the gen-tables under these circumstances.

Dear Iain,
thanks for Your helped. I succeeded with one splitpoint and midi-key
60, but I had now success with to different splitpoints.
Here is the (as short as possble) code:


-odevaudio -M1 -b400 ; fuer realtime-Midi

;jetzt gilt es, das erste  Instrument zu definieren

sr = 44100
kr = 4410
ksmps = 10
nchnls = 2
 ipch = 8.02
  iequal = 12



massign    0, 1              ; assign all midi events to instr 1,
pgmassign  0, 1              ; also all program changes
instr 1

 ituningtable = 10         ; the number of the f-table

 imnn    notnum
 indx    =  imnn * 2 + 1   ; values in table alternate between
 icps    table  indx, ituningtable
 icps    table  indx, ituningtable
  iamp    ampmidi    	1000
isplitpoint1 init 60 ; der Midisplitpoint 1 wird festgelegt, bei Taste 60
isplitpoint2 init 72; der zweite ist ne Oktave hoeher

a1    	oscil   iamp, 	icps, 1
a2	oscil	iamp/2, icps*1.1, 1
a3 	oscil	iamp/3,	icps*2.2, 1
amix1 	= a1
amix2 	= a1+a2
amix3	= a1+a2+a3
if (icpsisplitpoint1
; die Partiturereignisse werden definiert

; Tabelle #1, ein Sinuston
f1  0   8193  10   1
f 10  0 256 -23 "../skalen/12tet.cps"
;hier gilt es aufzupassen, ob die Pfadangabe stimmt
t 0 30 ; keine Ahnung, was das heißt

i1   0    3600 ; eine Stunde lang spielen

Sorry, I wanted to say:
I had no success!

Dear Iain,
thanks very much! Now I've understand (at least I think so), the
syntax of the if-clauses. It is not too difficult to understand, but
also not easy for someone like me, who has no experiences with
programming.
Again,
thanks!
Now I know how to do, what I want!
