Is there a way to move start and end simultaneously in waveform Mode? I think not?
Make the loop possible to automate in the DAW. In the trailer you written - turn sample into wavetable, but how it's a wavetable if I can't move position of the loop?
I'm use the term wavetable a bit loosely. You can move start and end simultaneously by pinning and moving the viewport around. For now, automating the loop is not a feature. I will consider making that a feature in a future release, it's just a bit tricky because that requires setting the bounds in terms of an inexact percentage.
