Hi I tried it a little bit,
first of all thanks for your effort, I think this is an amazing step for building loopers in axoloti
However I have some things that I would do differently:
From working with Ableton's Looper and Loopy I have a particular workflow that I really like and that I'm missing with your patch:
First Loop sets tempo (just like in your patch) BUT it isn't neccessarily a one bar loop. Ableton recognizes with longer loops, that it is several bars. With loopy you have to tell the software what kind of bar/length you're entering.
Other loops are set according to a quantization value rather than a fixed length.
That way you could start the first loop with a short rhythmic pattern and then add a longer melodic pattern on top or vice versa, and you do so by just keeping the same work flow, of starting and stopping recording with one switch.
So this would be a lot more flexible.
Furthermore some midi/clock sync mechanism would be great to. Like if there is no clock make one according to the first loop, if there is a clock synchronize the loops.
But still really great work! I really appreciate the loops saving function, really great for creating a musical sketch book.
If you like shoot me a pm, we could work at this together, I have a nice garden for patching in our backyard
