I am currently using poly~ to create myself a bath of granulizers/samplers. After much work I got 8 of them going, but I have run into a problem and wondered in anyone out there could suggest anything.

i Have 8 samplers running, all with their outputs falling out the bottom of the poly~.

The promlem is, I can't have all of them running if the volume for each on of them is 1/8 of 100%.

One will run fine with the volume at 100%

when i run two, i have to drop the volume on both to 50% (otherwise I seem to blow my DAC up [temporarily] )

Is there a trick I can use, so that If I am only running with one granulizer, I can boost the audio up to 100% and not be worried about breaking my dac as soon as I turn a second one on!?

I am in a quandry, any help would be greatly appreciated.

if you have two ouputs multiply the signal by .5 before the dac. If you have

4 multiply by .25. If you have 6 multiply by .16666 and so on.

Sure. I tend to use a lookahead limiter to get a gain of 1 at the end

of a dynmic mix of signals. The omx.peaklim~ can do this and you can

Sure. I tend to use a lookahead limiter to get a gain of 1 at the end
of a dynmic mix of signals. The omx.peaklim~ can do this and you can
change the response to your needs. P

You can use adoutput~ to get the sum of what you're sending to the 

output(s). This can be handy if you're using multiple dac~ objects to 

One more thing: make sure that you're not sending any DC offset. Like 

this you could blow up your dac even with silence.
