iACID8 — Hardware roots. Pocket acid. Born from the beloved Twisted Electrons Acid8 family, iACID8 brings the Acid8 to your iPhone—built directly from the uAcid8 Slim Synth’s original firmware, with its distinctive digital grit and hands-on sequencing intact. The filter gets a serious upgrade: a modern, TB-303-inspired algorithm delivers richer resonance, more expressive squelch and extra acid bite. Crunchy oscillators feed a smoother filter and cleaner output stage, keeping the low-fi character while letting every slide and accent shine. Start with 16 factory grooves, twist your sound into shape and build your own basslines. Record notes live, add slides and accents, or chain patterns and key changes into evolving arrangements. Play standalone or load iACID8 as an AUv3 instrument in your favourite host. Each plugin instance keeps its own patterns and sound settings, with optional host transport following and independent Run control. • 12 level-balanced waveform variations with distinctive digital character • Enhanced resonant filter with envelope, decay and accent controls • 16 editable patterns with slides, swing and live recording • Pattern chaining and recorded key changes • Arpeggiator, bit crushing, wobble and performance effects • MIDI input on channel 1 for notes and sound control • Standalone app and AUv3 instrument, designed exclusively for iPhone • Warm tube-style saturation in the upper third of the volume knob • Tactile haptic feedback in standalone mode • Ableton Link for jamming with apps and devices on the same network • Life slider for live rhythmic variations without rewriting your patterns • Illustrated playing guide and printable cheat sheet Your pocket acid machine—reborn for iPhone.

TAME THE NOISE: 4 Dynamic XY Pads: Instant tactile control over Feedback/Filter, Bite/Space, Ring/Fold, and Comb/Sub.
