the second release (v0.0.2) of “alsa-midi-latency-test” is available at: http://github.com/koppi/alsa-midi-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://earthvegaconnection.com/evc/product…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/koppi/alsa-midi-latency-…ter/benchmarks/ Any kind of feedback is greatly appreciated.
