Hallo, Patco hat gesagt: // Patco wrote:
I am not sure about that, DX7 has the usual ADSR, and level,
No, it has a unique envelope generator which used four pairs of "levels" and "rates" to be specified. This is more aking to a breakpoint envelope in the traditional sense, but it can be used to simulate an ADSR. Quoting the manual (pg 26, available here: http://www.maths.abdn.ac.uk/~bensondj/html/dx7.html):
NOTE If you are familiar with analog synthesizers that have Attack-Decay-Sustain-Release envelope genera- tors (ADSR EGs), you may recognize the line defined by R1 and L1 as the "attack" portion of the envelope. There are parallels between a conventional ADSR EGs and the DX7's EGs. However the DX7 envelopes are much more flexible than ADSR types because the DX7 offers 8 precisely programmable parameters (R1, L1, R2,L2. R3,L3, R4, L4) instead of 4 (A-D-S-R). I t ' s not really important for you to understand ADSR enve- lopes when you're programming the DX7, but if you already do and are curious about the comparison, see the envelope discussion in the Advanced Program- ming Notes section of this manual.
