This patch is heavily based on the Stepper from the brilliant 7up monome patch. I have built this patch from the ground up so it is entirely native to the Launchpad. It has a swing option, sequence length and a more flexible velocity section.
The S7epper controls 7 midi notes and includes a sequencer page, which allows for 8 pages for variations. The top buttons, left-to-right, control Sequence page/Swing/Velocity page/Play-Stop. The buttons on the right select which page is viewed. Like the 7up stepper, you can also copy one page to another by holding one button and pressing another.
v1.1 – bug fixed for the Swing function coming on the wrong beat sometimes.
v1.5 – fixed red lines staying on the pads, looks cleaner now.
v1.6 – fixed bug with copy/paste system. Rearranged layout on LP, added LED feedback to show what page is being played, put sequence length controls in the velocity page. Added scroll feature. Patch GUI updated. Note length added for using synths rather than drums.*
v1.8 - Compatibility with LP Nexus improved
*Now available - LP Nexus - use multiple patches at the same time with one Launchpad --- https://gum.co/IYRIL
