QmidiNet is a MIDI network gateway application that sends and receives MIDI data (ALSA Sequencer and/or JACK MIDI) over the network, using UDP/IP multicast. Inspired by multimidicast and designed to be compatible with ipMIDI for Windows.
LoopBe1 ~ Virtual MIDI Driver
LoopBe1 is an internal MIDI device for transferring MIDI data between computer programs. Basically LoopBe1 is an ‘invisible cable’ connecting a MIDI out port of an application to any other application’s MIDI in port. All MIDI data sent to the program’s output is channelled to the receiving applications in realtime. You may connect up to eight applications to LoopBe’s in port and up to eight applications to the out port, all sending and receiving at the same time.

LoopBe1 is a native Windows™ WDM kernel mode driver, so expect the lowest possible latency. Programs do not need to link with special libraries, so LoopBe1 works with every MIDI or DirectMusic™ capable application.
QmidiCtl ~ MIDI Remote Controller
QmidiCtl is a MIDI remote controller application that sends MIDI data over the network, using UDP/IP multicast. Inspired by multimidicast and designed to be compatible with ipMIDI for Windows.

LMS Plugins ~ Extend Logitech Media Server
LMS is an open source multi-room audio system. It was created by SlimDevices and then acquired by Logitech. Although Logitech has ended development of hardware devices, the project is still very active with lots of plugin released regularly. New hardware players can be added using PI devices and DAC boards to build high-quality multi-room systems.
I’ve created some extra plugins, especially to include new standard hardware / players to the LMS ecosystem: UPnP/DLNA (Sonos), ChromeCast and AirPlay.

Polymeter ~ Compose Polymeter Based Music
Polymeter is a MIDI sequencer for music that’s in multiple prime meters (1, 2, 3, 5, 7, 11, etc.) simultaneously. Each track has its own loop length, and when the lengths differ, the tracks “slip” (or shift phase) relative to each other. The resulting interference pattern is sufficiently intricate that variations similar to the embellishments of a live performer can be generated algorithmically.
Features:
- Multitrack step sequencer for polymeter
- Each track has its own loop length
- Any number of tracks, of any length
- Full clipboard support (copy/cut/paste)
- Unlimited undo and redo for all edits
- Multiple tracks can be edited at once
- Optionally shows current position within each track
- Drag reordering of tracks
- Exports a MIDI file
- Join adjacent steps to make tied notes
- Velocity editing
- Controller tracks
- Recording of live arrangement
- Editing of arrangement on timeline
- Inter-track modulation of mute, note, velocity, duration, position, and more
- Live performance view with full screen mode
- Recursive modulation (modulation of modulation) for mute and position
- Modulation graphing via Graphviz
- MIDI mapping of all parameters with learn mode
- Optionally transmits MIDI clock
