Read full description

Solitvde is a modulating shimmer reverb AUv3. We've packed early reflections, a diffusion engine, a modulation tank and a feedback delay network into one streamlined signal path, all tuned to run light on CPU. Inside the recirculating tank, a few granular pitch-shifting lines give a glassy, climbing shimmer. It's built around one principle: tweaking a parameter never introduces a click or a pop. Every control is modulation-safe from the get-go, which opens up a whole second range of expression and modulation to explore. Two tempo-syncable LFOs, a random source, and an envelope follower tracking the input can route to almost any control, so the space and time of the reverb fold in on themselves to give us solitude, at long last. FEATURES - Eight-line feedback delay network: Size, Density, and a true RT60 Decay in seconds. - Recirculating octave and fifth shimmer voices. - Two-pole tail damping that can roll off the high end. - Freeze as an amount, rather than a toggle, to hold the tail indefinitely. - Multimode filter (low-pass, high-pass, band-pass) in multiple signal placements, plus a low cut to prevent rumble accumulating. - Pre-delay, early reflections, stereo width, and mix controls. - Modulation matrix: two LFOs, a random source, and an envelope follower, routable to almost any control. Assign a source on a fader. LFOs sync to host tempo. - Factory presets to start from, plus the option to save your own. COMPATIBILITY (macOS) Runs standalone and as an AUv3 audio unit. Compatible with Logic Pro, Ableton Live, GarageBand, and any host that supports AUv3 effects on macOS 14 or later. COMPATIBILITY (iOS) Runs standalone and as an AUv3 audio unit. Compatible with GarageBand, AUM, Cubasis, and any host that supports AUv3 effects on iOS 17 or later. — Timothy J. Barraclough / Horse Parade

The call

The clearest difference is price: Solitvde Reverb at $6.99 against StringMaster Pro's $14.99. Solitvde Reverb also leads on rating (5.0 vs 4.5) and update cadence (every 6 days vs every 3 months). StringMaster Pro's advantage is ratings volume (20 vs 3) and iOS requirement (13.0 vs 17.0). On ads, in-app purchases, monetization model and device support there is nothing between them.
