Polymeter 0.0.17 adds recursive modulation

Version 0.0.17 of Polymeter introduces a powerful new feature called recursive modulation, also known as modulation of modulation, or N-order modulation. For example, suppose you have a note track, and want its note to be modulated differently at different times. You could create two different modulator tracks, both modulating the note, and alternate between them by manually muting and unmuting them. But what if you want to automate the alternation? Now you can, by creating a mute modulator for each of your note modulators. If the two mute modulators have opposite step patterns, the result is that the two note modulators alternate, just as if you were alternating them by hand.

The key point is that you can now create multilevel hierarchies of mute modulation, whereas before modulation was essentially flat, with only one level possible. The hierarchy is limited to 32 levels, but this should be more than adequate. It’s possible to create an infinite recursion, but the application detects this and displays an error message.
