Ever considered doing some type of pulse width “modulation” natively in Renoise? It got the tools to do it…just don’t expect exact ratio/percentile control.
Pretty simple process:
- Within an instrument you’ll lay down 3 FX chains
- “Input” chain sends the same audio to two other FX chains.
- “Inverse” chain inverts the audio signal and uses the delay DSP to modulate the delayed audio signal. A Hydra DSP or Macro is recommended for controlling the delay L/R offset parameters. Note that you’ll need to mute the source to not amplify the original signal. The Send parameter can be modulate to act as a “Dry/Wet” parameter. Be sure you place a gainer FX on the track to invert the audio.
-Lastly the “Mixdown” chain to mix both audio signals into one.
As I said earlier, it’s not precise due to the fact ever note operates at a different frequency. You’re modulating the time it takes for a signal to invert and play instead. So technically speaking this is more of a “pulse width time modulation method” but it gets to the point. Beyond that caveat it’s a nifty trick for certain applications if you find you need it.
Demonstrating a saw wave applying this concept.
