I suppose the controls are pretty self explanatory. Simply put, you drag the sliders to set probabilities for the notes you wish to be part of the sequence, for the octave distribution, then probability for a note to appear on each position (64 lines hard-coded), and velocty curve for the generated sequence. Then hit “Generate” and you have it. Copy the XML data and paste it on a track in your Renoise pattern.
I managed to get some pretty neat melodies, basslines and drum sequences with it.
Try it if you like. Let me know if you have any ideas for improvement. I feel kinda enthusiastic about developing this little thing further.
