It's in there! ;-} Now, you might have already tried Fluidsynth, but I thought I would mention it for completeness. Fluidsynth is also a soundfont player which "might" be more aimed at realtime synth. It has it's own sets of problems though, none that really matter to me though, I think it's an excellent synth. /Robert ps. As for the CPU hogging, fluidsynth had a problem earlier when the reverb was enabled. When there was little or none signal into the reverb it went totally bonkers and consumed pretty much all cpu (a denormal problem I seem to remember). So the obvious question is, when timidity consumes all cpu, is the reverb enabled? ds. > > mvh // Jens M Andreasen > <...> -- http://spamatica.se/music/
