(a screenshot would be worth a thousand words) it might seem that your playing is just human and seldom matches the rigor of the metronome ;) if what you're after is quantization _while_ recording, please check View/Options.../MIDI/Capture/Quantize global setting. however, i would recommend you do all quantization _after_ recording, via Tools/Quantize... from the midi clip editor menu (aka piano-roll widget). > When I listen to it then it seems to be in sync but of course this makes > editing in Qtractor useless because everything is displayed delayed. > The same happens with rosegraden so it doesn't seem to be a Qtractor bug. > again, how much is the delay? > I'm using a MidiSport 2x2 Midi-Interface but I don't think the delay > comes from there because when connect my keyboard directly with e.g. > LinuxSampler then I can play very nicely (short latency) > what it seems might not be precise enough. maybe you can run and compare to benchmarks with this gem: http://github.com/koppi/alsa-midi-latency-test byee -- rncbc aka Rui Nuno Capela rncbc@xxxxxxxxx _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
