Interphase B / test scope

Prepared from the owner-approved MonoSlide mix B, with viewport changes only.
43 modules; 92 cables; all sounds, phrases and connections preserved.
The extracted ZIP is checked in an isolated Rack Free 2.6.6 profile on
macOS ARM, with only the required free plugins and no account or licences.
A diagnostic-only free Recorder is used for signal tests, not by the patch.
Checks cover native recall, five MIDI lanes, loop returns, headroom,
dropouts, mono compatibility and unexplained note-end spikes.
The separate demo is a native Rack window recording with direct stereo audio.
No added text, microphone or desktop audio. The supplied patch is unchanged.

Windows and Linux are not tested here.
These checks do not guarantee CPU load or audio-device latency on your machine.
If playback crackles, try a larger audio buffer before editing the patch.
