05. Using Splitting Hares as an Audio Rate Wavefolder - matthewfriedrichs/HotBunnyManual GitHub Wiki
While Spitting Hares is a CV processor, there is nothing stopping you from using it as a wavefolder.
Let's look at: Example 11 Splitting Hares as a Wavefolder
This patch is built as a basic synth voice, but if you don't have a MIDI input source like a keyboard or DAW, you an just remove the ADSR out from the LIN input of the VCA. The LFO below the MIDI input is sweeping the MUTATE parameter, and the range of modulation is set from the lower Dual Attenuverter. Before we get to discussing the rest of the patch, it is important to point out that both the input and output of Splitting Hares is shifted down by -5V to keep it in the AC audio range that all audio rate oscillators should use. We just use a single Dual Attenuverter to accomplish this shifting.
Now that we have the boring parts covered, we can discuss how to shape the folding. As usual FORM is very powerful and dramatically affects the overall harmonics in the wavefolder. In the middle the folds are more gentle, but to the extreme ends of the knob the harmonics will become strong and alias heavily at high frequencies. In many ways FORM acts as a low pass filter on the wavefolding. The wavefolding itself is actually done from the MUTATE parameter. You can sweep the mutate parameter manually, but more typical use is to use an LFO or envelope to sweep the wavefolder automatically. SPLICE is set up to crossfade between the sine and triangle output of the VCO, but any waveshape can be used. At this point, I would strongly encourage you to replace the stock VCO module with one of your personal favorite VCOs and experiment with the wavefolding options presented by Splitting Hares. There isn't too much to it. Just set the FORM and MUTATE parameters to taste. SHIFT can be used to set the relative symmetry of the wavefolder, but it does not have a dramatic impact on the timber of the output.
That's how to use Splitting Hares as an audio rate wavefolder. I have not come up with any interesting uses for the multiple outputs in this mode. If you do come up with a patch that uses them, please let me know!
