Atmosphere machine. Texture generator. Harmonic workstation. A dual-engine audio sustainer with intermodulation, advanced filtering, support for custom samples, and more – all in the service of adding depth and character to your music. Coastline uses a combination of additive and granular synthesis to stretch sounds infinitely. It creates complementary ambience for any sound or composition. It brings a textural “je ne sais quoi” that makes your tracks stand out and feel more alive. Move as quickly as you want: slap it on a track for instant atmosphere, or use it as the recording and processing hub of entire compositions. All recordings happen immediately and automatically – set one volume threshold, and sit back. ENGINES AND EFFECTS • Tide – an additive synthesizer for reimagining sound. Control which frequencies of the input are mapped to oscillators, rebalance them to highlight harmonic or inharmonic characteristics, and introduce new frequencies with waveshaping. • Glade – a granular synthesizer that stretches sound forever with no clicks or transients. Balance the original timbre of your sound against Tide’s distillation of it. • Audio Matrix – route any channel in Coastline to intermodulate another. Create unique harmonic distortions, or load samples to introduce a completely new texture. Includes built-in field samples for naturalistic textures. • Filter – a multi-mode filter for all audio in Coastline, featuring feedback modulation, stereo spread, and independent per-channel controls. • Reverb – a downsampling reverb with a highly configurable chorus section for blending the results of Coastline and introducing another layer of texture and modulation. FEATURES • Modulation – modify any control in Coastline with multiple LFOs, sequencers, smooth random sources, and performance effects. • Presets – full preset control over every parameter in Coastline. Cross-platform preset format for sharing with friends. • Waymaker – connect to Coastline’s sibling application, Waymaker, for sequencing and additional control over the pitch of Coastline’s output. Includes 20+ presets by Peter Bark and imago meri. Also available for macOS and Windows in VST3 / AU / AAX formats from Aqeel Aadam Sound.

We rebuilt the legendary micro composer of 1983, then gave it everything the original owners wished for: eight voices, MPE, a sequencer worthy of the name, and a couple of new dirty tricks. The voice is the one you know: a single fat oscillator with sawtooth and pulse (manual, LFO, or envelope PWM), a three-mode sub oscillator, and a noise source, mixed and driven into a classic four-pole lowpass filter. One snappy ADSR, switchable env/gate VCA, and an LFO with triangle, square, stepped random, and noise shapes, complete with onset delay, tempo sync, and retrigger. Portamento with the proper on/auto/off modes, and gate, gate+trig, and LFO trigger modes, exactly like the hardware. And the a sequencer: eight patterns of up to 64 steps, drawn right on the panel, with accent, slide, and octave per step, follow actions and repeats, swing, and tools to randomize in a key and scale, mutate, copy, and rotate. Play a pattern from a held key, transpose it from the keyboard, lock it while you browse presets, and run it from its own clock, the host transport, or an Ableton Link session in the standalone. Sequences save with your presets. • Eight-voice polyphony, or the original mono behavior with the flip of a switch • MPE support with per-note pitch bend and pressure, four aftertouch destinations (VCO mod, VCF mod, filter freq, LFO rate), and adjustable pressure smoothing • MTS-ESP microtonal tuning, retuned continuously while notes sound • SPREAD for stereo voice panning, and AGE, which drifts each voice like forty-year-old components • A full drive section: pre-filter saturation, filter drive, post-VCA distortion, and a tilt EQ • Velocity to filter and amp • A chicklet keyboard with latch and octave shift, playable right on the panel • Full preset manager with favorites and a factory bank • Five faceplate colors, including one for console cowboys • AUv3 and standalone, with an interface that fills whatever window your host hands it AD-202 works everywhere iOS makes noise: AUM, apeMatrix, Logic Pro, GarageBand, Cubasis, and any other AUv3 host, plus a standalone app with its own audio and MIDI settings, Ableton Link, and background audio. No subscriptions. No accounts. No nonsense. Buy it once, own it forever.
