The instant one of the 16 step keys is pressed, it toggles the on/off mode and no knob movements made are stored for that step.In addition, by holding down the step buttons while using knobs compatible with motion recording, the values recorded with the step for that part can be edited and new motion data can be recorded.
It would be really useful to be able to enter motions in step mode, rather than trying to time knob movements in live record mode - especially for things like level/pan variances for percussion.
Am I missing something simple?
