MRP Sequencer is a software step sequencer conceptually very similar to vintage analogue step sequencers such as the ARP 1601/1603 and Korg SQ10, and recent digitally controlled step sequencers such as the Frostwave Fatcontroller and Colin Fraser's P3. MRP Sequencer goes a little beyond the feature set of most step sequencers.
