the D20 and D10 were also based on samples and 2 basic waveforms but the PWM was taken away. D20 has a sequencer. the LA-Synthesis was introduced and the D50 sold well after the big DX7 success (yamaha). it had some samples like the shakuhachi along with 2 OSCs and upper + lower structure, there was a 3rd party multimode expansion available (when using it all the D50 was 8 voice polyphonic. samples could not be filtered.
der D20 und D10 bringt die samples des D50 aber der Syntheseteil wird etwas abgespeckt: keine PWM mehr. die beiden waren eine Art D50 für weniger "Betuchte". D20 hat einen sequencer. nach dem großen Erfolg des DX7 kam dann die LA-Synthese des D50, Samples im Stile eines Shakuhachi Samples kamen zusammen mit einer klassischen 2-OSC Struktur mit ins 6 LFOs, bei Nutzung alles Stimmen mit upper + lower struktur, war er dann 8 Stimmig. Samples waren nicht filterbar.
8 parts, one of them being for drums. FX. one structure has 2 OSCs, so combining them it is 4 OSCs and 3x2 = 6 LFOs. per structure it had a pitch env and one per filter and one for amp.
8 parts - davon einer drums. FX. eine structure hat 2 OSCs, daher hat die zusammen 2x2 = 4 OSCs und 3x2 = 6 LFOs, dazu kommen je eine pitch ENV und pro Filter und Amp je eine Mehrsegment-ENV (wenn lower + upper genutzt).
