Re: [fluid-dev] Panning with stereo samples

Hi Aere, I'm responding publicly to your private message to me, to keep this discussion open and not have unfinished threads dangling on the mailing list. You asked if there are other well-defined controls that you can use, as your drop-down only offers those and not the undefined ones. There are

Re: [fluid-dev] Panning with stereo samples

Hi Aere, having read your document, I now understand what you mean. Ok, you use the currently unused CC 8 in your midi router for different purposes, controlling expression. And you fear that if we implement balance properly now, that you can't use your setup anymore, because CC 8 will now have a

[fluid-dev] Panning with stereo samples

Hi all, the panning control (CC 10) currently doesn't really work that well with SoundFonts containing stereo sound (actually with any instrument that has samples with off-center panning). When an instrument is made up of two samples, one panned hard left (-50) and the other hard right (50) and w
