Synthesizer TB 303 Bassline

DOH1 is a hands-on music production app for creating electronic beats, drum patterns, acid-style basslines, synth sequences, chords, effects, pads, ambience, and sample-based ideas on Android.

Build layered patterns and loops with a flexible 16-step sequencer. Program each section separately, combine patterns, adjust tempo and swing, and use randomization when you want a new starting point.

Create and shape your sound:
- Program drum patterns with multiple kits and individual sound controls
- Write bass, synth, and chord sequences with step editing
- Add transitions, impacts, pads, and ambient textures
- Import up to four samples and edit them in a waveform view
- Trim and split samples, change speed and pitch, add fades, normalize, reverse, and use zero-snap editing
- Automate sound parameters and control how quickly they change
- Mix every section with level, three-band EQ, pan, reverb, ducking, mute, and solo
- Protect the output with the master limiter

Capture your work:
Record your performance, create a WAV file, and save or share it from your Android device. Save projects in slots, reload ideas, and copy patterns between positions to build variations.

DOH1 combines sequencing, sound design, sampling, automation, mixing, and WAV recording in one focused workflow for electronic music creation.
