I see. thanks. There seems to be a fluidsynth MAX/MSP plugin that is a little newer and with a working tuning-keys command: https://forge.ircam.fr/p/fluidsynth4max/source/tree/master/src/fluidmax.c
So if there is somebody willing to maintain that binding, that would maybe be a better starting point. Cheers Marcus _______________________________________________ fluid-dev mailing list fluid-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/fluid-dev
