As with all the circuits presented here, you can modify the time constants by choosing different values for the A, D, and R Pots, and the 2. The transistors and diodes are not labeled in the schematic. The key difference is a buffer between the Sustain pot and the Decay Pot. Make sure you add a 2. It is preceeded by a transistor circuit which buffers the input and generates a short pulse which is needed to trigger the timer.

The key difference is a buffer between the Sustain pot and the Decay Pot. Or say if you want to use 1Meg pots, just increase the 2. It is preceeded by a transistor circuit which buffers the input and generates a short pulse which is needed to trigger the timer. A 1Meg resistor can be added to the circuit to provide for some input hysteresis, this improves triggering on slowly changing waveforms. Make sure you add a 2.

The original circuit was found in the Music Machines diy-archives. Make sure you add a 2. Also you can modify the ohms series resistors at the pots to influence the minimum time. A 1Meg resistor can be added to the circuit to provide for some input hysteresis, this improves triggering on slowly changing waveforms. This is indicated in dotted grey. This makes the decay time independant of the setting of the sustain pot, and results in very snappy decays.

Generally the time depends on the product of R and C, so if you increase the pot value or the cap value the maximum time increases. Or say if you want to use 1Meg pots, just increase the 2. The original circuit was found in the Music Machines diy-archives.

Unlike the first circuit the attack portion of the ADSR goes immediately to decay when the gate goes low. This is the circuit that I now use, since it has more musical properties. The original circuit was found in the Music Machines diy-archives.

Make sure you add a 2. In the first circuit the attack once triggered goes until the 10V threshold is reached, regardless of gate going low. It is preceeded by a transistor circuit which buffers the input and generates a short pulse which is needed to trigger the timer.

It needs a beefy signal for the gate, about 10 Volt or more. A 1Meg resistor can be added to the circuit to provide for some input hysteresis, this improves triggering on slowly changing waveforms.
