I would love a sampler with the following:
Usage of 2 samples per octave: C and F#. The rest of the notes are pitched using these sounds.
This would create a very light full keyboard sampler.
Loop ON/OFF switch. When off, control decay of sample with a knob.
With "Loop ON" using sampled strings or an organ.. oh God, imagine a real Farfisa
Reverse audio ON/OFF
LFO, filter control, reverb, etc.
It would be of great help to have a sampler with the first 3 bullets, and some additions would be the cherry in the cake.
Finally, I would like to thank the people in this community who are creating so many amazing patches for this little blue magic box.
