Microfreak/Preset/219 Dusty Bass

• Notes

  • Harmonic bass with a resonant filter, changing partials and envelope-controlled brightness.

  • Saved export and provenance

    • Saved export: September 28, 2026 MIDI Control Center user-bank archive, computer-bank slot 29, file 29-09282026 6h14-A29.mbp. The computer-bank slot differs from this page’s observed device slot.
    • The parameter payload matches Factory 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: HARM. Spread sets the spacing of partials; Rectification reshapes each partial; Noise adds phase-modulated noise and affects clipping.
    • Spread: 0.500.
    • Rectification: 0.471.
    • Noise: 0.452.

  • Filter

    • Low-pass filter. Saved cutoff: 0.157; resonance: 0.720. Cutoff and resonance are normalized settings, not hertz or instrument display values.

  • Envelopes

    • Main envelope: attack 0.000, decay/release 0.661, sustain 0.924. Amp Mod is on, so the main envelope controls loudness.
    • Cycling Envelope mode: Loop. Stored RiseLvl 0.180, FallLvl 0.134, Hold 0.521, Amount 0.186. These are normalized stored fields; rise/fall times in milliseconds remain unverified.

  • LFO

    • Smoothed random; clock sync on. 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 / Spread: −0.001. A small envelope route changes partial spacing.
    • LFO → Wave / Spread: +0.111. Smoothed random modulation changes partial spacing.
    • Cycling Envelope → Timbre / Rectification: +0.017. The envelope changes partial rectification.
    • ENV → Cutoff: +1.000. The main envelope strongly opens the filter.
    • Cycling Envelope → Assign 2 → Cycling Envelope Amount: −0.051. The envelope modulates its own output amount.
    • All other saved matrix amounts are zero.

  • Performance and session context

    • The main envelope sustains above zero and opens the filter. The cycling envelope and smoothed random LFO change the oscillator spectrum.
    • Paraphonic mode is off 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/26/10/12-Mon references this sound. The session context does not identify which recording passages use it.

  • 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/06 Dig Osc/03 Types/16 HARM describes oscillator controls. Microfreak/UG/05 Connections/02 Matrix and Encoder/01 Sources and Destinations explains the matrix and expression row.
