Ableton wavetable lfo does not cycle through the wavetable like intended

Post by carrieres » Tue Jun 04, 2019 10:12 am

Hi,
Ableton wavetable lfo does not cycle through the wavetable like intended, it makes a pause before restarting the cycle.
Setting the global time in the matrix to -50% allows the lfo to restart without pause.
This is a weird behavior, i would like a explanation.
Does anyone know how to cycle through the wavetable with a lfo without pause ?

The "pause" is when the LFO values go beyond the table, so it just keeps playing the last valid one, until the LFO goes back into valid values.

Seems the LFOs are bipolar and the Wave Position parameter is additive.

So when the LFO is -25 and the Wave Position is at 0, it adds to -25, but there is no -25 waveform, so it will play the first waveform until the LFO gets into positive values again.

You can set the Wave Position to 50% and the LFO to 50 (in the Mod Matrix) to cycle to the whole wavetable.
