B-Step Sequencer
B-Step Sequencer is a multitrack software MIDI step sequencer that is available as either a standalone application or in audio plug-in format (VST and Audio Units). Primarily used to create melodical sequences to trigger soft or hardware synthesizer, whether in a studio environment or live on stage, it has a user interface based on pattern and TR music sequencers.

History 
The first version of B-Step Sequencer (1.0), developed by the German company Monoplugs, was released in December 2013 for Microsoft Windows, Mac OS X and Linux. In March 2014 Monoplugs released the B-Step Sequencer for iPad, providing the same functionality as for desktop computers. Version 2.0 was released in October 2014 with two new supported platforms: Android and Raspbian (Raspberry Pi).

Features 
B-Step Sequencer has a long list of features, including full MIDI and MIDI beat clock sync support, Sequencer Ratcheting, shuffle (swing), monophonic and polyphonic note playback modes.
