Hi list,

I'm trying right now to do the signal graph with the help of channels. The setting is that I have something like the following:

chn_a "OUT", 3 ; read/write on "OUT"

instr player
	asig diskin2 p4, 1, 0, 1
	chnset asig, "OUT"
endin

instr out
	ain chnget "OUT"
	outs ain, ain
endin

alwayson out

now I want to have serveral instances of player running that i want to switch off later on, so my scorefile looks kinda like this:

i player.1 0 -1 "somefile.aiff"
i player.2 5 -1 "otherfile.aiff"
i -player.1 10 -1
i -player.2 15 -1

But player.2 is inaudible, since (i think) the channel may only be written by one instrument via chnset at once. If I replace the chnset in "player" by chnmix, both instruments are audible, but an annoying feedback starts to get louder and louder until the sound is shut off. With 'connect' this will not happen, but I can' use it, and I also want to have several instances of the same instrument. How can I achieve the functionality i desire?

Best Martin

You should use chnmix instead of chnset, but remember to zero out the channel after you've read it. Like this:

instr out
	ain chnget "OUT"
	outs ain, ain
	azero = 0
	chnset azero, "OUT"
endin
