oscillations in the timbre. This is partly the result of the feedback loop and our settings for
the FM K . From a psychoacoustic perspective these slight modulations in the timbre go

appear from the interference of the detuned pitches. Notice though, that although the oscillators have two different
pitches, only one pitch is readily perceived and the two oscillators merge together to create one sound. The detun-
ing and modulation of pitches is a psychoacoustic trick to make sounds merge together and have a "fatter" timbre.
The Shaper section allows you to fatten up the sound.
This is a good moment to inspect the shaper effect. This nonlinear effect is very powerful if
used within a feedback loop. If you turn up the D
and 2nDh K you can see the potential for fat and funky sounds. For now we leave the
