hello eric, the dac~ object are useless if more then one, i believe it is the same then if you would use just one dac~ object as it is the output. if you have some better soundcard, perhaps something external then you could use dac~ with arguments like [dac~ 1 2 3 ] and it would mean to what channels/output you sound goes.. right now it all goes to one output and i believe that since you have one osc~ going that it is not really a multiple oscillator..

i tried your patch and then i did this one, where each oscillator has a small difference in frequency and it makes nice rolling sound.. there is also a *~ object which can be used wherever you need to control the amplitude of the sound, now it is used for all osc~ at once, but you might as well put every osc~ through a separate *~ - thats how you could control how much you can hear a particular osc~ .. your patch didnt make any noises in windows when put to zero,, the best way to see if sth is making noise is just to disconnect it from the dac~ ..
