Nota Aurora

Nota Aurora is a wavetable synthesizer. Two wavetable oscillators (plus a sub) sweep through spectral tables that you scan and warp, then run into two filters, two envelopes, two LFOs, a modulation matrix, macros and a built-in drive · chorus · reverb block. It excels at evolving pads, digital basses and moving, animated timbres.

The Nota Aurora device card: the position/cutoff/unison live strip and the Osc tab with the 3-D wavetable stack, two oscillators, sub and unison.

Overview

Section titled “Overview”

Each voice runs two wavetable oscillators and a sub through the filters and amp:

Osc 1 ┐
Osc 2 ┼─ route per source (F1 / F2 / Both / Dry) ─▶ Filter 1 · Filter 2 ─▶ amp ─▶ FX ─▶ out
Sub   ┘                                              (parallel or series)

An oscillator’s tone comes from a table (a stack of single-cycle waveforms) — the position scans through the frames, and the warp reshapes each frame. Envelopes, LFOs and the matrix animate position, cutoff and more.

Interface

Section titled “Interface”

The card (mockup 2j) is a live strip over a tab rail that swaps the body.

  • Live strip — POS (wavetable frame), CUTOFF, UNISON detune, and Poly / Mono, reachable from any tab.
  • Tab rail (left) — Osc · Filter · Env · LFO · Mod · FX.

The tabs:

  • Osc — a 3-D view of the current wavetable, the bank chips (Analog · Pulse · Formant · Chroma) and warp modes (Off · Sync · Bend · PWM · Fold), the two oscillators (position, warp, level, pitch), a Sub (wave, level, octave) and a Unison stack (voices, detune, spread).
  • Filter — a Filter 1 / 2 selector with type (LP · HP · BP · Notch · Morph) and 12 / 24 dB slope; a response graph with freq / reso / env / LFO; and a Routing panel sending each source (Osc 1, Osc 2, Sub) to F1 / F2 / Both / Dry in Parallel or Series.
  • Env — Env 1 (→ amp) and Env 2 (→ position / cutoff) as interactive A/D/S/R graphs.
  • LFO — LFO 1 (shape, rate, depth, sync) and LFO 2 (shape, rate, depth).
  • Mod — an 8×7 drag matrix plus four macros.
  • FX — a built-in Drive, Chorus (amount + rate) and Reverb.

Parameters

Section titled “Parameters”

Live strip:

Parameter Range What it does
Pos frame 1–16 Scans through the wavetable’s frames.
Cutoff 20 Hz…18 kHz Filter 1 cutoff.
Unison 0–50 c Unison detune spread.
Poly / Mono — Voice mode.

Oscillators:

Parameter Range What it does
Bank Analog · Pulse · Formant · Chroma The spectral table set.
Warp mode Off · Sync · Bend · PWM · Fold How the frame is reshaped.
Position / Warp 0–1 Scan through the table / warp amount.
Level · Pitch (oct/semi/detune) — Per-oscillator mix and tuning.
Osc 1 On / Osc 2 — Each oscillator has its own bank, position and warp.
Sub wave · level · octave Sine/square/triangle sub oscillator.
Unison voices · detune · spread Unison stack width.

Filters, modulation and FX:

Parameter Range What it does
Filter 1 / 2 type · slope · freq · reso · env · LFO Two SVFs; type includes a Morph.
Routing F1 · F2 · Both · Dry Where each source (Osc 1/2, Sub) goes, in Parallel or Series.
Env 1 / Env 2 A/D/S/R Amp envelope and a free envelope (→ position/cutoff).
LFO 1 / LFO 2 shape · rate · depth · sync Two modulators (sin · tri · sqr · S&H).
Mod matrix 8 × 7 Sources (Env 1/2 · LFO 1/2 · Velocity · Key · Mod Wheel · Random) to destinations (Pitch · Osc 2 · Position · Cutoff · Reso · Level · Pan).
Macros 1–4 value · dest · amount Manual offsets into the destinations.
FX Drive · Chorus (+ rate) · Reverb Built-in output effects.

Tips & recipes

Section titled “Tips & recipes”
  • Evolving pad: assign Env 2 → Position (or LFO 1 → Position) in the matrix so the timbre morphs as the note sustains.
  • Wide digital bass: raise Unison voices and detune, keep it Mono, and route both oscillators through Filter 1 in Series with Filter 2.
  • Vowel textures: pick the Formant bank and sweep Position with an LFO.
  • Instant polish: add a touch of Chorus and Reverb on the FX tab.
