I love the Digitone as well. it's 4 part multimbral and the 8 voice are shared across all 4 parts. people tend to think of the Digitone as a FM synth, (and they wouldn't be wrong) its architecture is very much like a subtractive synth but in a normal east coast subtractive synth the architecture kinda looks like this: VCO -> VFC -> VCA Digitone: 4 operators FM engine -> VFC -> VCA (then ADSRs for the filter and the amp). the other think thats kinda interesting about the FM section of the Digitone, is it uses a form of additive synthesis to create the harmonic series for the HARM parameter. Additive synthesis is one of the oldest forms of electronic sound generation. this allows you, like the TX81z to have operators that aren't sine waves. So in a lot of respects the Digitone is more versatile that your standard 6op sinewave FM synth.
