Natural Gate
Capabilities 2
- Envelope Generatorenvelope-generator
- With nothing patched into IN, an internal DC voltage is normalled to the input so the channel's envelope profile appears at OUT. Envelope output amplitude is 0 to +10V unipolar.498
- Lowpass Gatelowpass-gate
- Two independent zero-bleed LPG channels with voltage-controllable decay, three material profiles, and both HIT trigger and CTRL envelope inputs. 100% analogue, not vactrol-based.498
Jacks 10 — 8 in / 2 out
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (8) | |||
| CH1 CTRL | cv | — | Pre-EG CV input for gate openness. Normalled to 10 VDC internally. Features an input clamp; negative signals may be clipped. CTRL trimmer scales this input.498 |
| CH1 DECAY | cv | — | CV input for decay time. Summed with DECAY slider setting. Negative levels subtract from slider; positive levels add. No normalisation to DC (unlike CTRL). DECAY trimmer scales this input.498 |
| CH1 HIT | trigger | ≥0.25V | Trigger input. Accepts nearly any signal; fires the gate envelope when input exceeds +0.25 V regardless of source amplitude, shape, or length.498 |
| CH1 IN | mixed | — | DC-coupled audio or CV input. When nothing is plugged in, a DC voltage is normalled so the envelope profile appears at OUT.498 |
| CH2 CTRL | cv | — | Pre-EG CV input for gate openness (channel 2, mirrored). Normalled to 10 VDC internally. Features an input clamp; negative signals may be clipped.498 |
| CH2 DECAY | cv | — | CV input for decay time (channel 2, mirrored). Summed with DECAY slider. No normalisation to DC.498 |
| CH2 HIT | trigger | ≥0.25V | Trigger input (channel 2, mirrored). Accepts nearly any signal; fires the gate envelope when input exceeds +0.25 V.498 |
| CH2 IN | mixed | — | DC-coupled audio or CV input (channel 2, mirrored). When nothing is plugged in, a DC voltage is normalled so the envelope profile appears at OUT.498 |
| Outputs (2) | |||
| CH1 OUT | mixed | — | Gate output. Carries processed audio when IN is patched, or the channel envelope (0 to +10V unipolar) when IN is unpatched.498 |
| CH2 OUT | mixed | — | Gate output (channel 2, mirrored). Carries processed audio when IN is patched, or the channel envelope when IN is unpatched.498 |
Parameters 10
| Name | Type | Range | Behavior |
|---|---|---|---|
| CTRL Trimmer (CH1) | knob | -1 – 1 | Attenuverter for CTRL input. With nothing plugged into CTRL, also acts as a pre-EG offset since CTRL is normalled to 10 VDC. At noon, gain = 0 (0V offset). CW increases positive offset; CCW inverts/reduces.498 |
| CTRL Trimmer (CH2) | knob | -1 – 1 | Attenuverter for CTRL input (channel 2, mirrored). With nothing patched into CTRL, acts as pre-EG offset via 10 VDC normalisation. At noon, offset = 0V.498 |
| DECAY (CH1) | fader | — | Offset control for decay time. Sets the pivot point for the DECAY CV input. Very short clicks at minimum, multi-second ringing at maximum.498 |
| DECAY (CH2) | fader | — | Offset control for decay time (channel 2, mirrored). Sets pivot point for DECAY CV input.498 |
| DECAY Trimmer (CH1) | knob | -1 – 1 | Attenuverter for DECAY CV input. Only active when a signal is applied to the DECAY input jack (no DC normalisation on DECAY).498 |
| DECAY Trimmer (CH2) | knob | -1 – 1 | Attenuverter for DECAY CV input (channel 2, mirrored). Only active when a signal is applied to the DECAY jack.498 |
| MATERIAL (CH1) | switch | 1 – 3 | 3-position switch selecting material character. Up = hardest (bright, very fast attack). Middle = softest (slowest attack, muffled, lower volume). Down = balance between the two.498 |
| MATERIAL (CH2) | switch | 1 – 3 | 3-position switch selecting material character (channel 2, mirrored). Up = hardest. Middle = softest. Down = balanced.498 |
| OPEN (CH1) | fader | — | Post-EG offset control for gate openness. Raises or lowers the floor of the envelope, holding the gate open to varying degrees.498 |
| OPEN (CH2) | fader | — | Post-EG offset control for gate openness (channel 2, mirrored).498 |
