QMidiArp is an advanced MIDI arpeggiator, programmable step sequencer and LFO for Linux. It can hold any number of arpeggiator, sequencer, or LFO modules running in parallel.
Arpeggiators produce sequences depending on the notes sent to their input port, which is typically connected to a keyboard or another sequencer. Step sequencer modules allow you to create simple linear, monophonic and globally transposable sequences similar to the first analog sequencers. MIDI LFO modules produce MIDI controller data of adjustable waveform, time resolution, amplitude and duration.
