4-track sampler / sequencer Naive tracker is a modern, minimalistic implementation of the vertical sequencer concept known as "tracker", designed specifically for small screens with touch interface and optimized for a fast and easy workflow. - single screen editor: immediate access to everything - sleek monochrome UI - ready to use: comes with a collection of synthetic lo-fi and acoustic instrument samples - sample browser: load / play samples super fast from anywhere in the file system - record samples - sample editor: select, trim, normalise, reverse or draw the raw wave form - random: shuffle parameters for new inspriration - pattern list: switch patterns live, chain patterns in a loop or arrange a song - export / re-sample: save complete songs as wav file - Ableton Link: plays in sync with any Link enabled app/device The two-dimensional note editing with instant transpose function enables a clear and compact sequencer where everything happens in a single layer. Patterns can be selected manually, play as looped range or in linear order so that the pattern column is suited for live performance as well as song arrangement. The 16-step sequencer grid may be extended with meta step, variable track length or by looping a chain of patterns. Specs - 4 tracks - 16-step sequencer with variable track length - 8 samples, max. 2.7 sec. each - 16 patterns - 256 patterns song length Sequencer parameters - note value (octave / semitone) - pitch envelope - pitch LFO - AD / gate / D envelope - volume / panning - offset / loop length - filter high / low pass - meta (play steps conditionally) No in-app-purchases, no subscription, no ads, no AI.

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.
