Check out our ADSR project using the AS3310 here.
The CEM range of synth chips featured in numerous commercial and DIY synths in the 80’s before they ceased production. A number of the chips have been remanufactured by a Latvian electronics company and we delighted to be able to offer them through Soundtronics. Going forward, we will be designing synth modules using these chips.
The AS3310 is a self-contained, precision ADSR type of envelope generator intended for electronic music and other sound generation applications. Attack, decay and release times are exponentially voltage controllable over a wide range, and the sustain level is linearly voltage controllable from 0 to 100% of the peak voltage Vp. All four control Inputs are Isolated from the rest of the circuitry so that the control pins of tracking units may be simply tied together.
