Rivet 02
Read full descriptionHide full description
Rivet 02 - Room is a room-style reverb with drive built for techno and industrial. Put it on drums, synths, or any bus to add space, texture, and character—from clean rooms to vintage digital crunch. Room works both as a standalone app and an AUv3 plugin. Room is an AUv3 audio effect and requires a compatible host app. It does not run as a standalone instrument. Room combines the CrunchCoat reverb engine (16-delay Householder matrix network) with pre-filters, saturation, and optional gated reverb—plus an underlay layer with tempo-synced ducking for kick pumping effects. KEY FEATURES • 17 room modes (clubs to halls) • Pre-filters, predelay, and gated reverb • Optional underlay with tempo-synced auto-duck RIVET SERIES / OPEN SOURCE • Room is part of my Rivet series of AUv3 effects plugins targeting techno and industrial genres. Room uses the CrunchCoat algorithm by Chris Johnson (Airwindows), made available under MIT license. AUv3 Effect • Works in AUv3 hosts such as AUM, Drambo, Logic, and Cubasis IN-APP PURCHASE Room includes In-App Purchases for optional tipping. Tipping does not unlock any additional features as all features are already available.
Synesthesia Synth
An experimental audio-visual instrument that allows users to sculpt evolving spatial audio by manipulating floating capsules. Position, rotation, and pulse changes affect tone, texture, and synchronized particle generation. It's a visual synthesizer, not a game.

Synthaestesia is a free experimental audio-visual instrument. Three capsules float in space. Every contraction produces sound. Move them, rotate them, reshape their pulse — and sculpt evolving spatial audio. Position changes tone. Rotation alters texture. Delay generates synchronized particles. This is not a game. It’s a spatial synth you can see.

Verdict
The clearest difference is in-app purchases: Synesthesia Synth at none against Rivet 02's 3. Rivet 02's advantage is update cadence (every 5 days vs every 10 days). On price, ads, device support and iOS requirement there is nothing between them.
