There are two things to keep in mind here: 1. Are events handled sequentially in time? 2. How many events can be transmitted in a unit of time? If events are handled sequentially in time, then it is not possible to play a chord of multiple notes at _exactly_ the same time. On Mon, Feb 16, 2015 at 5:11 PM, Jonathan E.

Its faster - but there are still limitations. Regarding the above: -Sequentially handled: yes -Bandwidth: lots better than DIN-cable MIDI, but limited > 2. I had not heard of MIDI-over-OSC. Yes - almost everything is possible with OSC - any form of data can be passed around as a "blob" of binary data, timestamps are available to be used for timing, and "bundles" can be used to have multiple events be processed at exactly the same time. Sequential handling? Yes - unless in a bundle. Bandwidth: unlimited. > 3. Is JACK MIDI constrained in the low timing resolution of original MIDI, or is it more flexible? JACK MIDI is sample accurate - and multiple events can be written on a single audio frame (internally in JACK graph). Sequentially: No - except on playback to hardware devices Bandwidth: configurable (at compile time IIRC), but "lots". > Others ipMIDI: Not much techie stats online available - http://www.nerds.de/en/ipmidi.html rtpMIDI: No details easily found on how it actually works - http://www.tobias-erichsen.de/software/rtpmidi.html Another list of MIDI over IP projects: http://openmuse.org/transport/mip_oview.html To sum up - JACK MIDI is awesome - its widely used, it is sample-accurate within the JACK graph, and events can occur at exactly the same times. With the QMidiNet project, broadcasting JACK MIDI over the network is possible, http://qmidinet.sourceforge.net/qmidinet-index.html I've not extensively used / or concidered-using the others - there's too much choice, and the advantage over JACK MIDI is minimal to non-existant.
