Is there a way to make a split of a signal in three ranges without spending to much computing power?

Something like svf~ does, but it has to be more accurate.

band one goes from 20-220hz and every frequency or harmonic content upper this range is discarded.

Check out the cross~ object and the forbidden planet fft example patch.

Hi! Maybe what you want is FFT. Have a look at tutorial no. 26 patch. Especially the subpatch called [p crossover]. You will get a good idea of ways you could do this.

I was in hope to avoid fft, to cpu expensive for this job.
