One of the reasons I reduced the full-blown DX operator clone to the uPop DX was to reduce the number of necessary components. With the complete operator you have an EG and keyboard tracking logic running whether you are using them or not. By separating the oscillator unit from the other parts of the operator you can use just what you need. If the standard ADSR will meet the needs of the patch, then it’s certainly the way to go. The DX7 EG is also linear, but has an extra stage and the ability to decay to a value other than zero. This can often be accomplished using the modulation attenuator and offset found in the utility/modulation section of the library. I added a brief intro to PM synthesis as addition to @RobertSyrett’s excellent “Know Your Nodes” segment on PM.
