Thoughts:
The above time frame might be a little underestimated as I did spend an hour or two earlier today producing code for a langsoundspeaks video. I reused some of that code and some of the live session to make this quick musical demo/test of performing the leap live…. I was pulling the lead notes out of the air, not really knowing if it would be the note I wanted… the notes were filtered to a scale, but other than that, i was guessing… Yup. I might want try that one again with some notation on the screen and make the lead notes more legato.
