I updated the sequencer I showed in yesterday’s video. You can download the new version from the same URL:
In addition to giving a 8 x 16 drum grid to program beats, the sequencer also has 8 multisliders (effectively step sequencers) in it that you can use to send volume changes, filter messages, whatever. The slider step sequencers are mapped to CC 10 – 17. You can change which one you’re controlling using the slider in the upper right corner. BPM control is right underneath.
I posted an Ableton .als with the midi mapping all setup to control an Impulse (multisliders mapped to volume).
