Custom LFO Shapes in Ableton Wavetable - Ableton Quick Tip

Turn one of your envelopes into Custom Shape LFO with M4L Shaper

For retrigger you can map velocity in M4L Expression Control to little R in Shaper, but in only works on non synced time mode (Hz). Little bit of math might be of help (or M4L Sick Calculation tools 1.1) if you want to sync it.
