TBDings (Stereo)

Description

CTAG TBD port of Mutable Instruments Rings — a polyphonic resonator that turns any excitation (pluck, noise burst, audio in) into modal / sympathetic / inharmonic-string tones. Three resonator models, each with frequency, structure, brightness, damping and a “position” pickup axis.

The TBD plugin variant adds:

  • Polyphony hold — Rings’ internal poly voicer is exposed (1 / 2 / 4 voices), with optional voice hold so chords ring out beyond the trigger.

  • Air blend — continuous low-level noise mixed into the exciter input, for bowed / breathy textures that don’t need an external excitation signal.

  • Chord / inversion / detune — for polyphonic mode, a chord-shape table with detune control (the same shape the rack’s PolyPad uses).

  • Velocity → exciter amplitude mapping so per-step / per-key velocity is expressive without an external CV.

The same engine is what the GrooveBoxRack’s tbd machine uses on CH12 (Lead2) and CH15 (Chordo). See Machines for the rack-internal id and source pointers.

Parameters (subset)

Param

What it does

model

Resonator model: 0 = Modal, 1 = Sympathetic strings, 2 = Inharmonic string.

freq

Note frequency / bias.

struc

Structure — odd/even partial ratio (model-dependent).

pos

Excitation pickup position along the resonator.

bright

High-frequency content of the partials.

damp

Resonator damping (release time).

poly

Polyphony: 1 / 2 / 4 voices.

chord

Chord index for polyphonic mode (PolyPad chord table).

inversion

Chord inversion 0..3.

detune

Per-voice detune amount (cents) — adds chorus / depth.

air

Air noise blend into the exciter input.

vela

Velocity → exciter amplitude depth.

envsh

Exciter envelope shape (impulse vs. sustained).

pluck

Manual pluck trigger (rising edge).

Use it standalone via the WebUI plugin list, or hosted on the GrooveBoxRack — components/ctagSoundProcessor/ctagSoundProcessorTBDings.* for the standalone, rack/RackTBDings.* for the rack-machine variant.
