Bendr 0.1.0 — Ink & Signal

Real-time pitch and formant shifting with spectral freeze and a pitched feedback
delay, built entirely from public pulp::signal primitives — no third-party DSP —
with a native GPU editor in Pulp's Ink & Signal design language.

Requirements: macOS on Apple silicon (arm64). This build is not universal —
it does not run on Intel Macs.

What it does

• Pitch ±12 semitones in real time, with formant control that can track
  the pitch (Link) or stand free, plus a preservation mode that keeps vocal
  character intact as the pitch moves.
• Freeze holds the current spectrum as a stationary resynthesis, so there is
  no loop seam to hear — and pitch and formant keep bending the held sound. Play
  it chromatically over MIDI.
• Pitched feedback delay, tempo-syncable, with a second pitch shifter inside
  the feedback loop so repeats climb or fall.
• Dry/wet with latency compensation.

Built from Pulp primitives

Primitive	Role
RealtimePitchTimeProcessor	pitch / formant shift, with FreezeHold and TransientPhasePolicy
PitchedFeedbackDelay	tempo-syncable delay with an in-loop pitch shifter
DryWetMixer	latency-compensated dry/wet

The editor is assembled from stock pulp::view widgets over a single
theme_from_preset("ink-signal") call. Numeric type-in fields use the shared
pulp::view::CaretBlink + paint_caret caret, so the caret holds solid while you
type and resumes blinking when you stop, at a rate independent of display refresh.

Bendr previously lived in the Pulp repo under examples/bendr. It now has its own
repository and consumes Pulp as an installed SDK.
