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
SL Prism

SL Prism is a precise, fast, touch-ready equalizer for corrective mixing and creative sound shaping. Create a band directly on the spectrum. Move it to set frequency and gain, then refine Q, filter shape, channel routing, dynamics, threshold, attack, and release. Every enabled response stays visible while you work. Use dynamic EQ to control frequencies only when they become a problem. Enable spectral processing for more focused reactions. Switch between Zero Latency, Natural Phase, and Linear Phase modes to match recording, mixing, and phase-sensitive work. Features: • 24 independent EQ bands • Nine filter types • Dynamic and five-slice spectral processing • Stereo, Left, Right, Mid, and Side routing • External sidechain support in compatible hosts • Realtime input, output, masking, and combined analyzers • EQ Match and resonance suggestions • A/B comparison, Undo, Redo, Auto Gain, Pan, Phase Invert, and Mix • Factory effects including Underwater, Telephone, Airy Vocal, Warm Vintage, and Lo-Fi Radio • AUv3 plugin and standalone app • Scalable interface for iPad Audio is processed locally on the device. Core EQ processing does not upload project audio.
