Developer Matthias Schorer has released StepSequencer ST-S01 – a classical step sequencer for the iPad.
ST-S01 features two modes with either 16 steps or two x 8 steps, which are executed in parallel on two MIDI channels.
ST-S01 supports MIDI Clock, Start, Continue and Stop. Each step has an octave and note selector, as well as a switch which permits skipping a step. In MIDI clock receive mode it is possible to slow down or speed up the sequence. MIDI can be received by WIFI and through interfaces like the Line6 Midi Mobilizer.
In the demo video, you can see the Step Sequencer ST-S01 in action. The ST-S01 is controlled by internal clock. MIDI is sent to Logic Pro via a Line 6 Midi Mobilizer and a Tascam FireOne Midi / Audio interface, which is also used to record the sounds of the vintage synthesizers used.
