Simple Sine Polyphony

#1

Hey guys,

Im looking at a axoloti to replace my laptop setup, i would love to put together a sinewave patch with multiple sine osc with Amplitude and Frequency control for each osc, to be controlled by a launch control xl. Anybody know how many voices i could achieve before i encounter issues?

I have patches with ADSR envelope, 4 oscillators and 2 filters per voice and chorus/reverb in the main patch. I can get to 6 notes polyphony, CPU usage on the Axoloti is above 90%.

Guess you'll have to test it to see how many voices you can have with a configuration that suits your needs.

How many sine oscillators do you plan to use per voice ?

#4

i'm not sure he means "oscillators per voice". it could also be voice=oscillator. that way he could of course get many of them running at the same time..

this would be more of a drone, noise setup then.

#5

yeah a kind of drone thing, i think 8 will be sufficient, maybe like thissine.axp (3.3 KB)

#6

well that patch uses 11 % on my axoloti, so you should be able to put at least 64 sine waves in there...

here is one with your setup doubled and a stereo out, it uses 21 %

Ordered, received, having fun with this.

Now to find a case :slight_smile:

You could also delve into object editing and substitute the 

SINE2TINTERP(p2,r);

line with 

r = sine2t[p2>>20];

This will give you a non interpolated sine function that's significantly cheaper than the original.
If you don't need fm you could also cut on that.

I created exactly what i was after for minimal droning, mapped to launch control XL, touch of reverb and channel 8 is filtered noise. I love this thing!sinemasterwnoise.axp (12.8 KB)
