QMidiArp

QMidiArp is an advanced MIDI arpeggiator, programmable step sequencer and LFO. It can hold any number of arpeggiator, sequencer, or LFO modules running in parallel.

Arpeggiator modules 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 independently produce MIDI controller data of adjustable waveform, time resolution, amplitude and duration.

For each module, an input note filter is available, and the output port and channel can be set independently. Since the modules use a common sequencer queue, they are automatically in sync with each other. QMidiArp works with an internal tick resolution of 192 ticks per beat. The queue can be synchronized to an incoming MIDI realtime clock or as a JACK transport client. Most of the relevant control elements are accessible via MIDI controller through a MIDI-learn infrastructure. QMidiArp also has a log tool displaying the history of incoming MIDI events in colors depending on their type. It has support for JACK MIDI and ALSA MIDI backends. QMidiArp runs on Linux and uses the Qt4 toolkit.

FEATURES

Programmable arpeggio patterns with preset infrastructure
Pianoroll-type display of arp patterns and cursor line
Envelope function for chord arpeggios with high polyphony
Latch mode or Footswitch for holding notes in arpeggio buffer
Keyboard-triggered or -restarted modes for all modules
Small input note delay making QMidiArp suitable for live play
Random and Groove functions
Synchronized MIDI LFO modules: LFOs have calculated and drawable waveforms, selectable frequency, amplitude, offset, time resolution and length
