The Sandsynth is a bitimbral monophonic granular synth, using the new sampler module. Other than midi notes, it has:
– 4 switches (either pushbottons or pedal switch)
Random length (for a bit of out of sync goodness)
Reverse
Freeze
Dual Channel (midi 1 plays both voices)
– 8 controllers (midi channel 1, 1-8 respectivey)
Grain size
Position
Density
Texture
Freq cutoff
Resonance
Noise
Reverb

It’s very tweakable and highly dependent on the samples that you feed it, specially if you use different samples for each voice. In that case recommend adjusting the sample length to match to avoid phasing issues.
