ENVELOPE / SAMPLE & HOLD / VCA SECTION
Patch points
● RATE input controls the speed of the envelope. It sets both the attack
and decay times.
● TRIG input triggers the envelope. The SEQ is normalized to this input,
and it triggers the envelope at the beginning of every step that has ENV
GATE enabled.
● CYCLE input can activate the cycling of the envelope when a positive
voltage is applied. It is only active when the CYCLE SWITCH is low (not
cycling).
● REVERSE input can invert the proportion between the attack and
decay times set by the SHAPE fader.
● EDGE output is a gate output that is HIGH when the envelope is in
the ATTACK phase. Adjust the SHAPE fader to make the gate longer or
shorter. EDGE is 3.5Vpp unipolar.
● ENV output is the main output of the envelope. ENV is 4Vpp unipolar.
● ACCENT input is a CV input controlling the VCA (voltage-controlled
amplifier). It can affect the final loudness of the Softpop.
It is designed
to work well with the GATE outputs from the sequencer to provide accents,
but you can also use voltages (HOLD, TRI, DYNAMICS) to control it. Use
the XY section to invert the DYNAMICS output and patch the signal
to the ACCENT input to obtain a compressor effect. (DYNAMICS to Y,
XY knob CCW, XY to ACCENT). You can also make the ACCENT input
responsive to the velocity of the incoming MIDI notes by patching it to
the sequencer CV output.
● SAMPLE input triggers when the voltage is sampled. By default, the
EDGE signal from the envelope is normalized to the SAMPLE input.
Patch CLOCK or other gates to SAMPLE to trigger it remotely.
● HOLD is the output of the Sample & Hold. Each time the rising edge
of a trigger is detected on the SAMPLE input, the TRI signal is held at
the HOLD output. It updates again with every newly detected trigger.
HOLD is normalized to the PITCH MOD input, so the PITCH MOD fader
effectively acts as a randomness amount for the Softpop. HOLD is 5Vpp.
