DOH1: Synthesizer 303 Bassline

Turn your iPhone into a hands-on groovebox for basslines, beats, melodies and evolving electronic music.

DOH1 combines a 303-inspired bass synthesizer, drum machine, melodic sequencers, chord tools, atmospheric sound generators and a flexible mixer in one focused music production environment. Build patterns, automate parameters, arrange musical ideas and record your performance as a WAV file.

CREATE EXPRESSIVE BASSLINES

Design deep bass sounds and classic acid-style sequences. Shape your tone with cutoff, resonance, envelope modulation, decay, accent, slide, drive, tuning and multiple bass models.

PROGRAM DRUM PATTERNS

Build punchy rhythms with a step-based drum machine. Choose from multiple drum kits and adjust the sound of individual instruments with dedicated controls for tuning, decay, tone, drive and level.

SEQUENCE SYNTHS AND CHORDS

Create melodies with the polyphonic synthesizer and step sequencer, or play notes using the integrated keyboard. Add chord progressions and arpeggios to develop richer musical ideas.

ADD TEXTURE AND MOVEMENT

Use pad and ambience sections to create spacious layers, evolving textures and atmospheric backgrounds. The FX section provides additional sound design with filters, delay, reverb, drive, pitch and width controls.

AUTOMATE YOUR SOUND

Bring patterns to life with parameter automation. Set individual automation speeds and define custom movement ranges for precise control over evolving sounds.

BUILD COMPLETE ARRANGEMENTS

Create, name and manage up to 32 patterns. Combine them in the Pattern Chain to develop longer arrangements and continuously evolving performances.

MIX EVERY ELEMENT

Balance your project with dedicated channel controls, volume, panorama, mute, solo, three-band EQ, reverb sends and sidechain ducking.

IMPORT YOUR OWN SAMPLES

Load short audio files and integrate your own sounds into DOH1 patterns.

RECORD AND SHARE

Capture your performance as a WAV recording and share or save it through the iOS share menu.

DOH1 is designed for electronic musicians, beat makers, producers and sound explorers who want an immediate, tactile way to create music wherever inspiration appears.
