Brusmaskin is a pocket groovebox — an 8-track synthesizer, sampler and sequencer for making complete tracks wherever you are. FOUR SYNTH ENGINES FM synthesis with a subtractive filter stage, a raw mono synth with drive and wavefolding, a lush 7-voice supersaw, and a dedicated drum synth with FM percussion, filtered noise and attack transients. Plus a sampler with slicing, key-mapped chopping, non-destructive trim and a start offset for ghost notes. DEEP STEP SEQUENCING Per-step trig conditions, probability, ratchets with pitch rolls, swing, and patterns up to 128 steps with independent speed and length. An arpeggiator with chord pools, inversions and free-run mode. Sound locks put a different sound on any step, and per-step parameter offsets shape your sounds over time. SONGS, NOT JUST LOOPS Chain patterns into parts, phrases and full songs. Perform live in the performance view, mix with per-track faders, and glue everything together with chorus, delay and a rich plate reverb. Sidechain ducking built in. HANDS ON MIDI learn maps any knob, fader or button on your controller to sounds, mixer faders, mutes and solos — with soft takeover so nothing jumps. 512 factory presets cover every engine, and an INIT patch per synth type gives you a clean starting point when you want to build from scratch. YOURS Projects and sample banks are stored in iCloud Drive as plain files you can see and back up. Three clock-syncable LFOs per sound, scale-aware note entry, and a built-in sample browser. No account, no subscription, and everything works completely offline.
