    Changed lines 4-10 from:
    Jurgen Haible design of MS10/MS20 type HADSR as additional envelope generator for his Synthi Clone ,from what he wrote on his page http://www.jhaible.de/tonline_stuff/hj_synclon.html : The Trapezoid Generator contributes to the Synthi A's uniqueness, and I wouldn't replace it, but sometimes a "normal" envelope could be useful as well. I chose the Korg MS-10 / MS-20 style Hold-Attack-Decay-Sustain-Release circuit as an additional EG. Component values are changed to match the +12V / -9V supply. The 1 MΩ potentiometers are a compromise. I've increased the integration capacitor to preserve the maximum time, but this also increases the minimum time. This is surely not optimal, and I may change it some time. (several MOSFETs in parallel ?!)
