These are the set of commands i feed into fluidsynth to startup resetbasicchannels load /usr/share/sounds/sf2/FluidR3_GM.sf2 setbasicchannels 0 0 1 setbasicchannels 1 0 1 ... setbasicchannels 14 0 1 setbasicchannels 15 0 1 select 0 1 0 0 select 1 1 0 0 ... select 14 1 0 0 select 15 1 0 0 pitch_bend_range 0 255 pitch_bend_range 1 255 ... pitch_bend_range 15 255

I cannot get it to do this again. so ignore this bit. > At fluidsynth initialization, the default value for pitch bend sensitivity is +/- 2 semitones. when i resetbasicchannels, it probably altered the default pitch bend sensitivity. But now i've set it explicitly with the pitch_bend_range 255, and works fine. So i'm not sure why fluidsynth has differernt audio levels, maybe it's the midi modes, but i've tried them and it still functions the same way. mmmoth On Sun, Apr 25, 2021 at 12:00 AM <fluid-dev-requ...@nongnu.org> wrote: > Send fluid-dev mailing list submissions to > fluid-dev@nongnu.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.nongnu.org/mailman/listinfo/fluid-dev > or, via email, send a message with subject or body 'help' to > fluid-dev-requ...@nongnu.org > > You can reach the person managing the list at > fluid-dev-ow...@nongnu.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of fluid-dev digest..." > > > Today's Topics: > > 1.
