Heyda, sorry for cross-posting: the first version of "alsa-midi-latency-test" is available at: http://github.com/koppi/alsa-midi-latency-test/ The console application aims to become a Linux drop-in-replacement for the Windows application "MidiTest": http://earthvegaconnection.com/evc/products/miditest/index.html It would be nice to hear some feedback, especially from - linux-audio-tuning users (-- what latencies are you measuring?!) and from - alsa-developers (-- would be nice, to include this tool to the alsa-utils package). Kind regards, ++Jakob
