The collection
The Rewind Bundle is the complete SonalSystem PortaTron catalog in a single purchase — every PortaPack library currently available, plus every future release added automatically at no additional cost. It is the most efficient way to acquire the full SonalSystem tape synthesis archive and the only way to guarantee access to new releases as they drop. The current library spans the full tonal range of the catalog: artist-curated loop kits from Sarah Belle Reid and René G Boscio, Buchla synthesizer sequences from FreqZ & TweakZ, modular cinematic soundscapes from Redstripedown, 4-track tape loop sessions from Sans Fin, lo-fi hardware texture packs, retrowave construction kits, dark cinematic loop suites, and ambient drone collections. At 461 cassettes and 1,800+ loops, this is not a supplementary resource — it is a primary production toolkit covering atmospheric scoring, electronic production, cinematic tension, ambient composition, and experimental sound design in a single package. The Rewind Bundle is priced to reflect the current library size and is updated as new PortaPacks are added.
