Network MIDI was invented sometime around 2004 to send MIDI messages over an IP network. To handle network loss, a protocol known as RTP-MIDI was created and documented as RFC-4695. Network MIDI is built into OSX computers and iOS devices. Apple music creators think nothing of connecting MIDI equipment using Ethernet and WiFi, instead of MIDI cables.
Sometime around 2009, Network MIDI was built into iPads and iPhones. This made building touch-based control surface Apps easy, and ensured they integrated with MIDI Workstations over WiFi. While this capability created many cool demos, the unpredictable latency and jitter of WiFi made MIDI-over-WiFi not attractive where timing is important. MIDI-over-Bluetooth became a standard in the last few years, and seems to be the preferred method for sending MIDI over wireless links.
But Network MIDI persists, and new implementations of the protocol as software pop up, as do new hardware products implementing the protocol. This article is a round-up of some of the implementations available in 2019.Read More »The State of Network MIDI (2019)
This month McLaren Labs releases
rtpmidi version 0.5.0 for Ubuntu and Raspberry Pi. This release brings some great new features, and also provides a few performance and installation improvements.
More MIDI message types … including SysEx
rtpmidi has always supported the following message types with full Journal capability for sending and receiving. (Note: The Journal is part of the error correction mechanism that recovers lost messages that occur when sent over a network.)
- Note On, Note Off
- Control Change
- Program Change
- System Reset
With this release, we also add the following to provide a complete set of MIDI message types including System Exclusive.Read More »McLaren Labs rtpmidi Version 0.5.0
Along with the recent release of McLaren Labs rtpmidi version 0.5.0, we have new ports to Raspberry Pi 4 Raspbian OS “Buster” and also Ubuntu… Read More »New releases – Raspberry Pi 4 and Ubuntu 19
A service is a program that the operating system automatically starts when it boots. On the Raspberry Pi “buster” operating system, the daemon that starts and stops services is called “systemd.” You can read about creating services here:
McLaren Labs rtpmidi can be run as a service so that whenever you start your Raspberry Pi rtpmidi can be ready to go. This is especially useful in a headless system where you want rtpmidi to route incoming RTP MIDI sessions to a specific MIDI destination.
One of our customers wanted to know how to do this, so we wrote up this HOWTO guide. Here we will show how to create a service that
- listens for incoming RTP-MIDI connections
- connects to MIDI Alsa port 128
- announces itslef on UDP Port 5006
- logs its output to Syslog
