Microfreak/Preset/174 Auster

• Notes

  • BasicWaves keys with moving waveform shape and expression-controlled sub level and decay.

  • Saved export and provenance

    • Saved export: September 28, 2026 MIDI Control Center user-bank archive, computer-bank slot 249, file 249-09282026 6h14-A249.mbp. The computer-bank slot differs from this page’s observed device slot.
    • The parameter payload matches Factory 2.0, 2.1, 3.0 and 6.0. This is an archived factory-equivalent baseline; it does not establish the instrument’s saved or unsaved state during a later session.

  • Oscillator

    • Model: BasicWaves. Morph moves from square to sawtooth to two sawtooths; Sym changes pulse width or the sawtooths’ relative phase; Sub adds a sine-wave sub-oscillator.
    • Morph: 0.918.
    • Sym: 1.000.
    • Sub: 0.669.

  • Filter

    • Low-pass filter. Saved cutoff: 0.000; resonance: 0.255. Cutoff and resonance are normalized settings, not hertz or instrument display values.

  • Envelopes

    • Main envelope: attack 0.000, decay/release 0.185, sustain 0.000. Amp Mod is on, so the main envelope controls loudness.
    • Cycling Envelope mode: Env. Stored RiseLvl 0.089, FallLvl 0.193, Hold 0.000, Amount 1.000. These are normalized stored fields; rise/fall times in milliseconds remain unverified.

  • LFO

    • Sine; clock sync off. Stored normalized rate: 0.148; division code: 0. The rate is not a hertz reading, and the musical division has not been converted.

  • Modulation matrix

    • Amounts use the signed normalized range −1…+1. The assignment destinations below resolve the saved Assign columns.
    • Cycling Envelope → Wave / Morph: −1.000. The envelope moves the waveform morph downward.
    • LFO → Timbre / Sym: +0.729. The sine LFO changes pulse width or sawtooth phasing according to Morph.
    • ENV → Cutoff: +0.728. The main envelope opens the filter from its zero base setting.
    • PRESSURE → Assign 1 → Sub: +1.000. Expression adds sub-oscillator level.
    • PRESSURE → Assign 2 → Decay/Release: +0.683. Expression lengthens decay/release.
    • All other saved matrix amounts are zero.

  • Performance and session context

    • The saved main envelope has an immediate attack and no sustained level. Expression changes bass weight and note length. The strong envelope-to-cutoff route opens an otherwise closed filter; Morph and Sym modulation change the oscillator spectrum.
    • Paraphonic mode is on in the saved export. The PRESSURE matrix row uses pressure or velocity according to the instrument’s global Utility setting; the export does not establish which expression source was used in the session.
    • GitP/A/Session/26/10/18-Sun references this sound.

  • Evidence and interpretation

    • Base controls use normalized 0…1 values unless a stored choice code is shown; matrix amounts use −1…+1. These describe saved base settings, before modulation, and are not OLED percentages, hertz or milliseconds.
    • The saved-parameter inspector preserves the original fields. Oscillator interpretation assumes the documented firmware 5 layout; firmware is not detected from the export.
    • Matrix columns and assignments follow the Freakout live map and assignment decoder. Mode and waveform labels follow the MicroFreak Reader definitions.
    • Microfreak/UG/05 Connections/02 Matrix and Encoder/01 Sources and Destinations explains matrix sources, destinations and the expression row.
