Hi Linux-Renoisers,

the second release (v0.0.2) of "alsa-midi-latency-test" is available at: http://github.com/ko...i-latency-test/

alsa-midi-latency-test measures the roundtrip time of a MIDI message in the alsa subsystem of the linux kernel using a high precision timer. It calculates the worst case roundtrip time of all sent MIDI messages and displays a histogram of the rountrip time jitter. The console application aims to become a Linux drop-in-replacement for the windows application "MidiTest": http://earthvegaconn...test/index.html

The second release of alsa-midi-latency-test includes a number of bug fixes with the high precision timer code. It also includes some benchmark results for future reference: http://github.com/ko...ter/benchmarks/ Any kind of feedback is greatly appreciated.

Kind regards,
++koppi

Something like this should be built-in into Renoise! In theory it could recalibrate PDC involving MIDI devices - maybe even when starting playback. Although, there'd have to be a short time-out and the option to ignore devices that have no MIDI return.
