miniVerb is an 8-bit/chiptune and lofi reverb effect inspired by the sound of 80s game consoles and retrocomputers. Early consoles didn’t have much power for DSP effects, so the video game composers at that time had to improvise. The most common way to add a sense of space/reverb to the sound was to sacrifice one of the internal tracks to play a delayed version of the original sound, essentially using a slapback echo to add depth. The technique evolved and eventually, consoles started to take advantage of more power for real internal effects. miniVerb recreates that classic digital echo/reverb sound, made famous by iconic consoles such as the NES and SNES, topping it with two filters (post/pre), vibrato, and crusher (bit crusher, downsampler, pitch shifter).

Evil Otto is a multiband OTT (Over-The-Top) compressor that applies simultaneous upward and downward compression across three frequency bands. The result is dense, hyper-detailed audio where peaks are controlled and quiet details are pushed forward — a sound heard across modern electronic music, pop, and hip-hop production. Features -- Three-Band OTT Compression Evil Otto splits your signal into low, mid, and high frequency bands and applies independent upward and downward compression to each. Quiet details come up, peaks come down, and each band can be tuned separately. -- Precise Control Without Complexity Fifteen parameters give you everything you need and nothing you don't: Depth, Time, independent Down and Up amounts, per-band thresholds, per-band output levels, and input/output gain. -- Sidechain Input Route an external signal to duck the compressed output for rhythmic pumping effects. A dedicated Listen mode lets you monitor the sidechain signal to verify routing. -- Real-Time Metering Nine meters show input levels, gain reduction, and output levels per band. The center meters display both downward compression and upward expansion relative to the threshold, so you can see exactly what the compressor is doing. -- Factory Presets Includes a library of starting points across a range of applications. Save and recall your own presets with the built-in preset browser. -- Cross-Platform Compatible User presets created on iOS work on macOS, Windows, and Linux. Sessions created in GarageBand or Logic on iOS will open the desktop version on macOS.
