QMidiArp
- A Linux MIDI Arpeggiator, Step
Sequencer and LFO
DESCRIPTION
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.
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.
A Global Storage Tool can store different setups and switch
between them at a given time. It allows you to dynamically combine
patterns and LFO wave forms.
For each module, an input note filter
is
available, and the output port and channel can be set independently. QMidiArp 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 Qt
toolkit.
The modules are also available as LV2 MIDI plugins. The LV2 plugin UIs use either Qt or the RobTK toolkit by Robin Gareus.
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
