Streams
Dual dynamics gate providing two channels of voltage-controlled filter and amplifier (VCFA), with envelope generation, vactrol emulation, envelope/frequency following, and dynamics compression modes.407
Capabilities 5
- Compressorcompressor
- Sidechain compressor/limiter using the VCFA; EXCITE input optionally used as sidechain. Attack 0.2ms, release 150ms. MOD controls ratio and makeup gain direction.407
- Envelope Followerenvelope-follower
- Analyzes EXCITE input for amplitude envelope and spectral centroid across 3 frequency bands; applies to IN signal's amplitude and filter cutoff.407
- Envelope Generatorenvelope-generator
- Two channels; EXCITE input triggers internal AD or AR envelope controlling VCFA gain and cutoff, with variable cutoff modulation amount.407
- Vcfvcf
- Analog low-pass filter integrated into the VCFA; cutoff modulated by envelope, vactrol, follower, or direct CV depending on mode.407
- Voltage-Controlled Amplifiervca
- Dual VCFA with direct amplitude control via LEVEL input; response curve adjustable from exponential to linear.407
Jacks 4 — 3 in / 1 out
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (3) | |||
| EXCITE | mixed | — | Multi-purpose control port; accepts audio or CV. Function depends on selected mode (trigger for envelope, vactrol input, follower source, or sidechain for compressor).407 |
| IN | mixed | — | Signal input for audio or CV. When unpatched, a +3.3V signal is internally routed to the VCFA, enabling envelope or CV output use.407 |
| LEVEL | cv | — | Directly wired to the amplitude control section of the VCFA; attenuated by the LEVEL MOD knob. When unpatched, a +8V signal is internally generated, so LEVEL MOD acts as an offset control.407 |
| Outputs (1) | |||
| OUT | mixed | — | 407 |
Parameters 6
| Name | Type | Range | Behavior |
|---|---|---|---|
| Function selector | button | — | Press to display the current function; press again to cycle through the four functions. Hold to access the second bank of 5 alternate functions. Hold both channels simultaneously to link them.407 |
| LEVEL MOD | knob | — | Attenuator for the LEVEL CV input. When no jack is in LEVEL, acts as an offset control over an internally generated +8V signal.407 |
| METER | button | — | Press to show the bargraphs; press again to cycle through the 4 visualization modes. Hold for 1 second to enter calibration mode.407 |
| MOD | knob | — | Adjusts the amount of brightness (cutoff frequency) modulation applied to the signal in addition to amplitude modulation. Behavior varies per mode (envelope amount, filter damping, compression ratio, or attenuverter for EXCITE CV in Direct VCF mode).407 |
| Response curve | knob | — | Adjusts the VCA response from exponential (fully CCW) to linear. Compressor mode requires exponential setting.407 |
| SHAPE | knob | — | Controls the overall attack and decay characteristics of the selected function — envelope times, vactrol or envelope follower reaction time, or cutoff frequency (in Direct VCF mode).407 |
