Nota Auto Filter
Nota Auto Filter is a filter with built-in motion: an envelope opens it as the sound gets louder (auto-wah, envelope filter), an LFO sweeps it in time (wobble, gates, slow motion).
Layout: the Shape column on the left (Cutoff and Reso faders, with the modulated value marked), a centre panel with three tabs — each one window where you see the cutoff move — a right panel and a status line.
Filter
Section titled “Filter”| Control | What it does |
|---|---|
| Type | LP, BP, HP or Notch |
| Morph | Blends continuously between the types |
| Slope | 12 or 24 dB |
| Freq · Reso | Cutoff and resonance — or drag the response |
| Drive | Pre-filter drive for colour |
| Circuit | Clean or Analog (saturating) |
Envelope
Section titled “Envelope”
An envelope follower: Amount (up or down), Attack, Release and Hold (a time, or infinite). It listens to the track itself or to a key — another track picked as the device’s sidechain source. The window draws the cutoff over time.
Amount, Rate (Free in Hz or synced to the tempo), wave — Sine, Tri, Saw, Sqr, S&H — with Morph, start offset, a stereo phase offset between the channels, and retrigger. The window draws two bars of it.
Output
Section titled “Output”→ Freq / → Reso — what the modulation moves: the cutoff, the resonance, or both. Mod smooth slews it, Gain trims, Dry/Wet blends.
