hey, would it be possible to crossfade between different buffered envelopes inside the SynthDef using Playbuf or Phasor / BufRd and multiply it with SinOsc for pulsar synthesis? instead of sequencing them with patterns.

Overlapping grains inside the SynthDef would be another thing then using Pulsedivider or other options…

thanks.
