FET Acoustic Compressor brings the warm, musical character of classic FET compression — voiced in the tradition of the Cali76 by Origin Effects and the vintage 1176 circuit it's based on — to your iPhone and iPad. Dialed in for acoustic guitar, but equally at home on electric guitar, bass, vocals, keys, or any source that benefits from that signature FET feel. Whether you're tracking at home, mixing in a DAW, or running signal live through Loopy Pro or AUM, FET Acoustic Compressor gives your sound the punch, presence, and glue it needs. Voiced for feel The compression curve, soft knee, and gentle FET saturation are tuned for the transients and dynamics of acoustic strings — but that voicing translates beautifully to any instrument that needs a compressor with character. It sits, it glues, it breathes. Full control, intuitive layout - IN — Drive the input and push into compression - ATTACK / RELEASE — Fast enough to catch a pick attack; slow enough to let the body bloom - RATIO — 2:1 to 20:1 for everything from gentle leveling to heavy squash - OUT — Trim your output level - DRY — Blend in parallel compression for the best of both worlds - SC HPF — High-pass the sidechain so low-end doesn't trick the detector - Gain Reduction Meter — See exactly what's happening in real time All-In mode Tap the RATIO label to activate All-In — the infamous "all buttons simultaneously" trick from vintage 1176-style compressors. Ratio jumps to 100:1, the knee tightens, and asymmetric FET saturation adds the gritty, pumping character that's made this mode a go-to for aggressive sounds. A secret weapon hiding in plain sight. Factory presets to get you started - Compressed Fingerstyle - Dynamic Fingerstyle - Pop Strumming Built for the mobile studio and stage - AUv3 plugin — use in GarageBand, AUM, Loopy Pro, Cubasis, and any AUv3 host - Low latency — optimized for live performance and real-time processing - 4x oversampled processing for clean, artifact-free compression - Designed for iPhone and iPad *Cali76 is a trademark of Origin Effects Ltd. 1176 and UREI are trademarks of their respective owners.

TwinPath enables parallel effects processing using your existing Audio Units, without configuring busses or complex routings. It hides the details of managing multiple signal paths, and offers a compact, quickly accessible control interface. The result is a consistent setup you can easily recreate in any DAW, regardless of how each host handles audio routing. Among its possible applications, TwinPath pairs especially well with delay effects for dynamic performances. Shifting focus from deep editing to switching between (or blending) entire modules opens up a new perspective and new features – especially when feedback delays are involved. And of course, both approaches can be applied at the same time. Once inserted into a track’s effects chain, TwinPath handles splitting and merging audio streams and provides several convenience features. It offers two main classes of operation: CROSS-FADE • Blend between two effects chains using a single control • Switchable pre/post operation: pre mode preserves effect tails and lets feedback effects "breathe", while post mode offers instant, direct control DUAL MONO • Run different effects chains for Left/Right, Mid/Side, or a continuous blend between them • Channel mapping and FX bias are smooth, performance-friendly controls • Quick and efficient workflow replacement that overcomes functional limits of stock dual mono modes, such as restrictions on independent preset loading PLEASE NOTE: • An AUv3-compatible host is required to use this app
