Hi Spectro, thanks for testing.
I'm not sure whether the gesture truncation you see is either a bug or a feature : it is intended for the gesture to be looped after one bar. If you start a new gesture in the middle of a bar the end of it might get cropped if you continue for too long. Does that explain what you experienced or do you think it was something else?
The scales : each layer controls five particles and each of them trigger note events : the scale multislider can specify a different note for each of the particles. Each of the five bars in the multislider represents an interval from the current layer's midinote value to the corresponding particle's note value. Is it clearer, or did I miss the point of your question?
You're right, I'll try to document this version a little more. Thanks for the features suggestions, the separate quantisation for each layer is already on my todo list for the next version.
