I wouldn't buy gear that has any visible modifications. These include extra holes, switches, knobs, lights/light colour change, etc. Also, I wouldn't buy any vintage analogue synth with retrofitted MIDI. As for the internal changes like expanded memory, updated OS, etc - it wouldn't influence my buy...

"Generation" implies that what's in there is a formula of sorts that has as result a waveform, and it turns into actual data at the last moment. Compare vectors and pixels. The quoted service manual indicates that there is a formula which takes the variables: sine value, frequency value and envelop...

Guess what - that's exactly how it works. There's a quarter of a rather high-resolution sinewave in a lookup table there, and it's mirrored up and down and left and right to create the whole sinewave. How do you think the new waveforms were "generated" on the TX81z and others? From the DX7 service ...

That definition classifies the Yamaha DX7 as a ROMpler. :lol: This would imply that DX7 has the sine wave stored not generated in real time. The fact that you can change the frequency of each individual sine wave operator within the range of 1Hz-9772Hz shows that the operators behave like real time...
