SIGNAL PRESSURE REVIEW
This is a continuation of the Registro Geminato system under field conditions.

The same players operate within the same two-register structure. The difference is control. The earlier document isolates and maintains strict separation between registers. Here, the system is allowed to run without fixed correction.

The low register remains stable. Mauro Valli holds long, even bass patterns with minimal variation. The upper register continues in short, articulated phrases from Giacomo “Jackknife” Valli. The relationship remains intact, but timing begins to loosen over longer duration.

Midrange expands. Luca Ferretti introduces sustained organ and ARP layers that sit between the two registers rather than measuring them. Enzo Calieri’s calibration tones appear intermittently instead of acting as constant reference. Giorgio Nardi reduces the drum kit to occasional structural entries.

Side A holds a stable extension of the original condition. Patterns repeat without defined endpoints. Side B allows partial overlap and drift. The two registers move closer, then separate again. Alignment is no longer enforced.

The system does not fail. It continues without correction.

TECHNICAL INFORMATION
• Recording Medium: ¼″ reel-to-reel (mobile field capture)
• Mix: Mono
• Duplication: Real-time cassette dubbing (ferric stock)

Signal Chain:
– Fender Jazz Bass → DI + cabinet blend
– Rickenbacker 4001 → direct + micro-amp
– Hammond / Farfisa → direct + amp capture
– ARP 2600 / Odyssey → direct line
– Drum kit → minimal mic configuration

Recording Conditions:
• Generator and alternator power fluctuation
• Open-air and semi-enclosed environments
• No corrective mixing

Mastering & Transfer:
• Direct transfer from field reels
• No normalization
• Level variance and tape saturation retained

TRACKLIST
Side A (18:20)
1․ Estensione Continua — 18:20

Side B (18:35)
2․ Ritorno Esteso — 18:35
Total Runtime: 36:55

ARTWORK & INSERTS
• Matte cassette sleeve
• Front: dual frequency bands extended and slightly offset
• Back: signal routing diagram with mobile annotations
• J-card interior: partial calibration notes and timing marks
• Cassette shell: off-white with stamped SSMU code

PHYSICAL DETAILS
• Ferric cassette (standard bias)
• Hand-duplicated in real time
• Slight channel imbalance on some copies
• Estimated 140 copies produced
• Distribution via SSMU routes, FPC relay chain, hand-to-hand circulation

ARCHIVAL STATUS
• No vinyl pressing
• No reissue
• Fragments appear in later SSMU field tapes
• Limited cassette copies remain in circulation
• Partial field reels in unstable condition
• No centralized archive

EPILOGUE
The structure remains in place.

Alignment is no longer enforced. The system continues long enough to be recorded, then continues beyond the document.
