Morpheus audio plugin — Linux AArch64 demo

A prebuilt Morpheus audio plugin for Linux AArch64, so you can hear what the plugin route
produces before compiling your own. Read PLUGIN-DEMO-NOTICE.txt first — it carries the
terms and the third-party licences.

This is the whole rig: the project owner's own Marshall JCM 800 2203 captured in four states —
Crunch, Crunch 2, Hi Gain (TS) and Hi Gain (RAT) — through a Marshall G12M 4x12 in four mics,
into a drive, a three-band tone stack, a delay and a spring reverb — nine blocks in the order a
pedalboard would have them. ⚠️ All four captures and all four cabinets ship with this build.
They are the project owner's own captures and are included with it; they are not third-party
material with a separate licence. Switch between them with the Capture and Speaker
controls in the plugin's own panel, or from the host's parameter list — they are the last two
parameters, Capture and Speaker. It draws its own control panel — the plugin owns the
sliders, so the standalone app has knobs rather than an empty window, and a DAW shows them
instead of its generic parameter list. Every control is in its own units (dB, %, ms).

⚠️ The standalone monitors your audio input — with a live microphone and the speakers
up, an amp model in a monitoring host is a feedback loop and it will howl. Use headphones, or a
DAW (where the host decides monitoring). And it is a captured high-gain amp: with the gate at its
lowest setting it has a noise floor of its own, so raise GATE to about -40 dB to silence it
between notes.
