I made a simple yet powerful and free sequencer for the launchpad and ableton live. Does not need M4L. It is a 64 steps sequencer divided in 8 independent rows. Enter sequencer mode with the "user 2" button. The other launchpad modes are still working. Only tested on osx with iac drivers, but should also work with midiyoke on PC.
Applikation and manual. you will find an english manual on the buttom of the blog entry.
