Spectrum Parameter Randomizer

Spectrum Parameter Randomizer is a tool for generating random patches for Spectrum, the amazing FREE AUv3 port of Mutable Instruments eurorack modules by Burns Audio. (Spectrum Synthesizer Bundle by Thomas Burns https://apps.apple.com/us/app/spectrum-synthesizer-bundle/id1467384251)

Select the Spectrum app being used (default = Spectrum). Parameters will be displayed across the knobs. Tap SHIFT to see the parameters other parameter pages. To randomize parameters, double-tap the Randomize knob, or set it to midway or higher, or send 64 or higher to the Knob 21 AU parameter.

MIDI cc thru is blocked by default but can be allowed. By default Pitch, Detune, Volume, and Input Gain are excluded from randomization but can be enabled by changing the Excl. Pitch and Excl. Volume knobs.

Other parameters can be excluded from randomization by holding down SHIFT while changing the knob value to zero. Sorry, at this time there’s no indicator of the parameter when it’s excluded. Temporarily re-enable it to see the parameter name again.

    Added Pitch and Detune to the parameters excluded by default. They can be enabled with the Excl./Incl. Pitch knob.

    Hey all, thanks for the kind comments!
    v1.0 has been finalized with the revised cc assignments from the latest Spectrum release. Please replace v0.2 with v1.0. Have fun!

    Version 1.1 includes changes to the cc assignments that were introduced with Spectrum v0.5. I hope to add pads for storing and retrieving snapshots in the next version, but didn’t want to delay getting the cc’s right any more than necessary.

    Eh. Sorry. V1.2 corrects midi cc’s for Resonator.
