Ok, your EWI controls the expression controller CC11. Additionally the value for noteon velocity is taken from that controller. For the first note you're playing the expression value is pretty low resulting in a very low noteon velocity. Low expression and low velocity gives a very quiet note:
B0 0B 16 90 03 16 For the next note CC11 is higher again: B0 0B 3E 90 01 3E Dont know how other EWIs handle noteon velocity. However, you could try: - assigning noteon velocity to a fixed value (e.g. 64), since you're controlling the volume via CC11 anyway, or - this might be an issue with the very dynamic volume processing introduced in fluidsynth 1.0.9. In this case it might help to test it with fluidsynth 1.0.8 or you start fluidsynth with the *-o synth.volenv=compliant* option (since this is a new feature you'll have to checkout this branch <https://github.com/FluidSynth/fluidsynth/tree/volenv> and build fluidsynth your own) Tom 2017-09-16 11:31 GMT+02:00 Freeman LIU <freemanliu2...@gmail.com>: > Attached is the log from > > amidi -p hw:1,0,0 -d > log > > > I blowed into ewi usb and changed fingers and octave rollers randomly. > > Thanks, > > > On Sat, Sep 16, 2017 at 5:44 PM, Tom M. <tom.m...@googlemail.com> wrote: > >> You could dump the MIDI events from your EWI to file, so we have a way to >> reproduce this issue. >> >> >> Tom >> >> >> 2017-09-15 15:19 GMT+02:00 Freeman LIU <freemanliu2...@gmail.com>: >> >>> Dear experts, >>> >>> I got a EWI USB and managed to make it work with qsynth and qjackctl. >>> Awesome.
