NOVA-Scale — Synth + Autotune

One plugin: 4-engine synth (Organ/Synth/Pad/FM) with built-in autotune-style scale lock. Pass-through, quantize, reassign (every key valid), or scale-run. Drop on any MIDI track. REAPER JSFX now, VST3/AU in keymatrix-vst3.

Duo-Path Pedalboard

Full kitchen-sink pedalboard. Use on guitar bus or mixdown. NOT for vocal tracking — that's what splits into the next card.

Open Hub → Visualizer

Bare-Bones Tracking Chain

Three split REAPER JSFX so REAPER doesn't stutter while you track. AXIS Track = input → 3-band EQ → delay on the vocal. AXIS Looper = separate bus. DL4 Delay = mono insert. Autotune is optional, never default.
