McLaren Labs was founded to bring missing MIDI utilities to the Raspberry-Pi and Linux computers. Our aim is to make music-creation more fun on inexpensive and small computers!
Our first product is Network Midi. You can also expect to see a tone generator in the near future. Check back for updates or send us an email to learn more.
Network MIDI lets MIDI-enabled software communicate by sending packets over your network. Just as file sharing enables one computer to use the files on another, Network MIDI enables synth-sharing over a network. Use this when your synth computer is already hooked up to your audio system and you want to use a MIDI keyboard or controller that is on another computer.
Because Network MIDI is built into Mac OSX, you can use a Raspberry-Pi or Ubuntu Linux computer to send MIDI information to your Mac. This allows you to "play" Mac synths from your Pi. You can also use a cheap Linux computer to "bridge" USB-MIDI keyboards and controllers into your Ethernet network.
Why RFC-6295? RFC-6295 (alsa known as RTP-MIDI) is a special protocol for MIDI information. Other systems (like OSC, for one) use either UDP or TCP protocols directly. UDP packets have low latency, but their delivery is not guaranteed. TCP messages are guaranteed to be delivered, but system buffers can introduce unmanaged delay.
RTP-MIDI is built using UDP packets but introduces a music-friendly error-correction algorithm. This algorithm detects when UDP packets have been dropped and recovers the information in a musically-friendly way. This means that if a Note-OFF packet is lost, that note will not stay "stuck on." The protocol will detect the missing Note-OFF and recover. This method gives the best experience for live performance.
rtpmidiyou can connect connect Synthesizers, Keyboards and other Controllers using Ethernet instead of old-fashioned MIDI cables.
rtpmidiprogram can be used as a Slave or a Master. As a Slave, it can accept incoming connections from other Network MIDI participants. As a Master, it can initiate connections to other Network MIDI participants.
