Anyone already tried to make a controller to fill the step sequencer?

Hi, I juste got a new idea today, build a controller with push button and rgb leds to use only for step sequencing midi clips, like the push2, do you know how to access the steps of the midi grid?

Hi benwadub,
That sounds very cool indeed! Also challenging since Live doesn't natively have a step sequencer onboard.
I reckon accessing the steps seems only a small part of building such a script, you need also to be able to input notes, velocity, gate,... I wonder if it wouldn't be easier if you would script around an existing M4L or VST step sequencer, since these already have all the functions programmed. Just a thought..

To answer your question, a way to access the 'steps' of the midi grid (inside a clip), could be by using the nudge function. By nudging you can 'walk' through the 'steps' of a midi clip.
The length of the nudge (or step) would be determined by the grid size. A clip with a fixed grid of 1/8 would have 8 'steps' in a one-bar loop. A grid of 1/4 would give you 16 'steps' in a one-bar loop.

I just saw that nudging means tempo change..
I meant nudging in a clip like the left and right arrows on the keyboard do.
Then again, the 'jump_by' function maybe can do the trick. The length of the 'step' would be the 'beats' parameter of the 'jump_by' function.
