Dual ADSR analog LPG with VCA and Filter modes
aka Single Andore
Dynamics are the name of the game here.
The LPG is a VCA-based circuit (fwiw it's analog), but since you've got the shape control and a 4-stage envelope you may dial in an imitation of whatever other circuit behavior you like. The mode button does the expected VCA/LPF/VCA+LPF switching. There is a 2-input unity gain mixer on the VCA. It has character.
Andore Jr. is a dual envelope (dedicated trigger ins and env outs, shared controls). Envelope 2 is accessed by holding a button down and modifying the desired controls. The shape control is a crossfade between linear and RC responses (log attack, expo decay). The velocity control has a dedicated CV input. It controls the overall height of the envelope voltage. Since it's shared between two envelopes, the velocity value is sampled at the start of each envelope trigger (Mysteron style). There is also a single general purpose CV input, assignable to any of the env stages or the shape control. The envelope mode button switches from ADSR to ADSD (with the fourth slider acting as the sustain time control) to AHD to AD (self cycling). CV inputs are shared between the envelopes but the attenuverters and destinations may differ. Nobody's forcing you to use the second envelope.
Trimmers are provided to tweak the linearity of the VCA in combo mode and to add a small amount of resonance to the filter. There is an analog VCA CV input and a dedicated attenuverter for sending Envelope 1 to the VCA.
Andore Jr. is designed to quickly and conveniently provide voice control to any sound source, and offer further modulation opportunities. Relax, it's supposed to be this simple. Offered as an alternative to the large/cranky/expensive/excellent Double Andore.
