Bunker Evolved

• Four tracks called AIR, MELODY, ROOT and SPARK share eight voices across 64 sounds and 24 worlds.
• Press PLAY and a world unfolds, with seven bounded mutation modes plus LOCK developing the pattern as it loops.
• GROW fits, nudges or regrows a phrase to a chosen root and scale, and OCT− undoes one step.
• MOTIF builds rhythms from 24 templates with density, length up to 64 steps and adjustable step rate.
• ALGORITHM picks the track, HOME and SELECT move through the six pages, and KNOB 1 to 4 match the display fields.
• STEP and DETAIL let you edit single notes, chords, ratchets, timing and velocity, and record chords from the keys.
• EDIT, ENV, LFO, FX, SCL, ARP and GLO open the full engine, envelope, modulation, effect and scale editors.
• SAVE keeps projects in four slots and sounds in 32 user slots, and the installer backs music up over USB MIDI.
