Re: [fluid-dev] tunnings

[Viktor Michna]

Hello Josh,
I don't think it's problem of FluidSynth, it does greatly his job and thank you 
for it.
Thing is that FluidSynth uses usual equal temperament which sounds slightly 
dissonant on some intervals (like thirds). This is general problem of whole 
western music and all conventionally used intruments (piano, guitar, flute, 
...).

http://www.justintonation.net/whatsound.html

My research deals with some kind of "cleaning" by small retuning of equal 
temperament in real time. Maybe if algorithm was ready, it would be good idea 
to built it into synthesizer, but I'm just at the beginning... There's already 
method called HMT (Hermode Tuning), but it deals only with some of intervals 
and more it's probably patented.
I'm testing on fluidsynth.dll build with patched function 
fluid_synth_tune_notes() to finally work in realtime (parameter apply).
BTW: How is it with latency?, I'm using USB MIDI keyboard and there's small 
delay between the keypress and sound...

Best regards,
Viktor
