EchoSketch turns delay and reverb into a live, playable instrument. Shape your sound in real time using a responsive X/Y performance surface designed for intuitive touch expression. At its core are four great-sounding delays: digital, analog, ping-pong, and reverse. The range for each parameter and the XY axes direction can be set independently, allowing you to easily morph between sounds. It works as an Audio Unit plugin or standalone — iOS or Mac. Comprehensive Delays • Digital (patterned after a legendary '80s rack delay), Analog (warm, with tape-style pitch glide), Reverse, and Left/Right Ping-Pong • Delay times can sync to tempo or be set in milliseconds • Feedback features delay-dependent tone shaping — bright for short delays and darker for long ones Convolution Reverb • Stereo or mono Spring, Plate, and Hall • Reverb path is separate from the delay (same as vintage tape echo units), so repeats don’t get washed out Modulation and Filter • Analog-style modulation for chorused, warbly pitch echoes • Tone control — darken or brighten delays, with a center detent for flat Designed for Hands-On Performance • HOLD / LIFT — leave the XY cursor in place, or touch the pad for momentary delay sounds • FREEZE — set the current feedback into an infinite loop and play over it • MOTION — record a gesture on the XY pad and loop it Presets and More • Presets are transferable between hosts • Two looks — light "Trail" and dark "Glow" • Works standalone with live audio or as an AUv3 plugin • Universal — iPad/iPhone also gets you the Mac version — one purchase • Mac: after installing, open EchoSketch once to use it as a plugin in your DAW • Works in AUM, AudioBus, GarageBand, Logic, and other AUv3 hosts

VU950 FX is an AUv3 effect plug-in built around a gritty 12-bit DSP model, designed to bring classic sampler-style tone shaping directly into your iOS music host. At its core, VU950 FX combines sample-rate reduction, 12-bit DAC character, input drive, bass and presence coloration, noise, and an anti-aliasing filter that naturally closes as the sample rate goes down. You can keep that authentic behavior, or edit the AA Filter manually to fine-tune how dark, crunchy, clean, or aliased the sound becomes. Use RATE to set the modeled sample rate, from cleaner high-bandwidth processing to darker low-rate texture. Use FILTER to shape the main tone filter from wide open to heavily rolled off. Use CHANNELS to choose whether the left or right input channel becomes the focused mono source. The jog wheel edits the active RATE or FILTER page. ON/+ and OFF/- switch the selected channel when CHANNELS mode is active. The top knobs give you direct control over AA Filter, Input Drive, and Output Gain, so you can push the DSP model harder, tame the final level, or dial in just the right amount of anti-aliasing response. VU950 FX is made for fast AUv3 workflows: load it in your favorite compatible host, automate the parameters, and turn clean audio into controlled 12-bit character in seconds.
