After 2 days of testing I would like:

Finer grid settings in general.

If I have a generated transition part, that I can move it and shorten/lengthen it wherever I want without the whole mix shifting with stems and samples, that's confusing.

When I generate a drum loop, it doesn't always run smoothly on the beat when I duplicate it. (First Drum comes always with an attack)

You should be able to adjust this more finely, loop length and start/end point of the loop. Many more tracks for mix and stems, samples. At least 8. If i have 1 track (beat and bass) and would like to add the vocals and effect or melo from the next one, it wont work.

You should also be able to cut the stems or tracks at any position in the mix and make them longer or shorter.

At least, if i put a stem or sample with echo/delay, it will be cutted at the end of the sample, terrible, better let the effect run out.
