Beautiful Bleep6. Signals
All signals are 32-bit floats, one per sample, in virtual volts, chosen so that bridges to CV hardware and VCV Rack map directly.
| Type | Value | Rule | Virtual volts |
|---|---|---|---|
control (0) |
bipolar −1..+1 or unipolar 0..1 | Polarity declared per output | ±1 ≈ ±5 V |
gate (1) |
high ≥ 0.5 | high ≈ +5 V | |
trigger (2) |
one sample of 1.0, otherwise 0.0 | Readers that decimate MUST take the maximum of the span | |
pitch (3) |
1.0 per octave | 0.0 = C4 = MIDI note 60 | 1 V/oct |
audio (4) |
reserved | MUST NOT be used in v0.1 |
Types and polarity are advisory: any output may be connected to any input. Values outside the nominal range are allowed (a sum of cables may exceed it); receivers clamp where it matters.
6.1 Applying modulation to a parameter
A receiving plugin SHOULD apply an input to a parameter as an offset in the parameter's normalised range (0..1), inside its DSP:
effective = clamp(knob_normalised + Σ source_i × amount_i, 0, 1)
It MUST NOT move the host-visible parameter (no automation writes, no undo entries). Parameters with exponential mappings (cutoff, rates) are thus modulated in octaves.
