What Berlinan does
- Berlinan is a generative Berlin School sequencer whose voices repeat, phase against each other on uneven loops and earn mutations.
- The FM-1 makes no sound: each voice goes out on its own MIDI channel to your synthesizers over USB.
- The ensemble holds two plucks, a bass, a pad, a lead, a drone and a heartbeat.
- You play from the panel: voice keys mute and select, white keys move the harmony, other keys fire scenes and snapshots.
- PRESETS picks the template, ALGORITHM picks the mode, EDIT re-rolls unlocked voices and OCT+ rolls a new seed.
- MASTER is a density fader that thins the ensemble from full down to silence at the next bar.
- SAVE keeps the project and six snapshot slots in memory, and OCT- undoes the last twenty states.
- The FM-1 sends MIDI clock, Start and Stop over USB, or follows a clock from USB, the TRS jack or both.
Its modes
- HOME: Perform
- You watch the voice lanes, the horizon of coming changes and the convergence, and set tempo, the arranger, form and ambient mode.
- ENV: Voice
- You see the selected voice's strip, generation and lifecycle, and set its MIDI channel.
- ARP: Pattern
- You read the selected voice's pattern step by step and set the ratchet probability.
- LFO: CC
- You view the selected voice's controller lanes and the template's scenes.
- SEQ: Arranger
- You follow the arranger's phases, the bars to the next change and which voices are in.
- FX: Delay
- You read a note division and its time in milliseconds per voice for your own delays and echoes.
- GLO: Setup
- You set the root, the clock source and its input, and the lights, and read the seed.
