Nice to hear some love for the DX9. I bought mine when they first came out. I= t has a slightly more aggressive (more analog like) sound. It is really good= on bass patches and bell like tones. It=E2=80=99s also good for controlling= non-keyboard modules or keyboard impaired synths like my Microkorg.

Then it took me a= round 3 hours with the manual starting from the init sound to get an idea ho= w one has to approach constructing sounds in FM. Since then I can make sound= s in a DX, which I have in my head. It takes me about twice as long as with a= subtractive synth, but for many standard sounds still under 15 minutes (usi= ng a hardware contoller). >=20 > I don't understand FM mathematically, but I understand, that there aren't t= oo many variations of sounds, and there are only a few important basic param= eters. There is frequency ratio between operators, there is modulator level (= with envelope) and you have to decide, whether your carrier operator runs wi= th keyboardcontrol at audio, or without keyboard-control at low frequency. > Algorithm variations are overrated. Of course they make a big difference i= f you have a finished sound and change the algorithm. > But for building sounds from the scratch, it does not matter too much, whe= ther two parallel modulators go to the same carrier or to two different carr= iers at the same frequency. The first will have a similar sound like Filter-= PolyMod on a Prophet5. The latter one will remind simply two oscillators wit= h VCF and VCA for each oscillator (like the voice architecure of Yamahas CS1= 5 / CS80). >=20 > Thats it. >=20 > Florian
