Software Description

QMidiArp is a MIDI phrase controller and generator LFO for the ALSA sequencer.

It has the ability to control multiple synchronized arpeggiators, LFOs and step sequencers. QMidiArp has been growing since june 2009 on top of Matthias Nagorni's original arp idea.

Features

  • Arpeggio pattern preset infrastructure
  • Synchronized MIDI LFO modules added LFOs have calculated and drawable waveforms, selectable frequency, amplitude, offset, time resolution and length
  • Synchronized step sequencer modules added Step sequencer can be transposed and velocity-modulated by received notes, sequence can be drawn on the fly
  • 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 arpeggiator mode
  • Input note delay strongly reduced making QMidiArp suitable for live play
  • MIDI-learnable control of many live-relevant functions
  • MIDI realtime clock slave synchronization
  • JACK transport client synchronization
  • Event log entries are color-coded, optional MIDI Clock event display
  • Re-designed graphical user interface: all modules and dialogs are dockable floatable windows, main and file icon toolbars added
  • New .qmidiarprc file containing GUI settings, user arp patterns and last file path
  • Save and SaveAs functions with modification monitoring
  • All relevant session parameters stored in new .qmax XML session file
  • Manual pages in English, French and German
  • Handler for SIGINT added to handle unsaved or changed files more carefully at program termination.
  • Handler for SIGUSR1 added to provide support for LADISH level 1.
  • Separate threads for ALSA Sequencer Queue handler and arpeggio engine

  • Non Session Manager support with "switch" capability
  • NSM support requires liblo development headers (liblo-dev package)

  • Groove Settings and LFO & Seq resolutions now also MIDI-controllable
  • One-click duplication of LFO and Seq modules
  • Option to add new modules in muted state
  • Vertical Zoom switch for Seq module display
  • ToolBars can be positioned vertically
  • Nested arrangement of modules allows more flexible layouts

New in v0.4.1
