ADverb2 is our love letter to the golden age of studio reverb: a small handful of controls, a big friendly panel, and a sound that flatters everything you run through it. Version 2.3 grows it from one algorithm into three. PLATE is the original ADverb algorithm, a classic digital plate with the fast build-up and silky decay that made these boxes famous. It remains untouched, and your old presets load exactly as before. AMBIENCE is a modern, airy space. It adds air and dimension around a source without an obvious tail at short settings, and blooms into a long, weightless wash when you push the time out. Time-varying early energy keeps it from ever sounding static. HALL is a large concert space, exceptionally smooth and very wide, with slow internal motion that keeps long decays lush instead of metallic. All three algorithms share the same simple control set: Pre-Delay, Reverb Time, Size, low and high Contour switches, Rolloff, and Diffusion, plus input level and output mix. The Input Mute and Reverb Stop kill switches let you perform with the reverb, choking the send or the tail on the beat. Mix Lock keeps your wet/dry setting pinned while you audition presets, ideal when ADverb2 sits on a send. Version 2.3 also brings our system-wide preset browser with folders and favorites, a hundred factory presets covering everything from drum plates to nine-second ambient washes, preset stepping right from the main panel, and presets that show up in your host's own preset menu. ADverb2 is an AUv3 Audio Unit and runs in any AUv3 host, including GarageBand and Logic Pro. The interface is fully resizable and scales to fit your device. No accounts, no ads, no in-app purchases.

BLEASS Flanger harnesses the sonic characteristics of classic flanger effects and brings them fully up-to-date with a pair of flexible LFOs, variable modulation routing, an envelope generator and beat synchronisation. Classic flangers are a delay-based effect, and modulate the delay time to create the distinctive, repetitive flanged sound. But with BLEASS Flanger, multiple modulation sources are combined to create detailed, complex and evolving timbral movement within your sound. The addition of an envelope generator, which is triggered by the incoming signal, adds an additional dimension to the flanger effect, making it sensitive to the dynamics and nuances of your performances. The second LFO can take the sonic possibilities further still, with the option for it to modulate the delay’s feedback strength or stereo width. The tonal character of the effect can be controlled easily thanks to the multi-mode input filter, whilst the ability to synchronise the LFOs to the beat of your music allows you to explore completely new rhythmic and evolving effects. BLEASS’ trademark interface design ensures this powerful collection of tools are both easy and fun to work with, so you can harness their sonic versatility without ever hindering your musical creativity. And with super-efficient CPU usage, and compatibility with all major hosts and DAWs on desktop, iPad or iPhone, BLEASS Flanger is the only flanger you will ever need.
