Start with a world
24 curated arrangements and 64 role-specific sound recipes give AIR, MELODY, ROOT and SPARK a musical starting point.
OUR INGREDIENTS / OPENLY CREDITED
A new way in.
Deep roots underneath.
Bunker Evolved combines curated ambient worlds and simple, reversible composition gestures with Felucca’s deep sound editing. That combination is its focus.
The Bunker difference
Keep the melody yours
24 motifs, 32 scales and GROW’s TUNE / SOFT / FLOW / NEW turn a phrase into editable notes. Keep a variation, undo it, or let EVOLVE continue.
Go deeper when you want
The approachable HOME pages sit beside Felucca’s synthesis, modulation, sequencing and project tools. The sound remains yours to shape.
Compared with our Felucca 1.6.1 base
| Area | Felucca foundation | Bunker’s addition |
|---|---|---|
| Sound | Engines, factory presets, filters, envelopes, modulation and effects. | 64 ambient sound recipes and 24 curated worlds. Recipes use and reshape existing sounds. |
| Composition | Four tracks, step sequencing, patterns, chance, conditions, arp and scale tools. | 24 scale-degree motifs; seven bounded sequence transformations with per-track chance, interval and LOCK. |
| Harmony | 16 scales in the pinned base. | 16 further established scales, bringing the menu to 32; a friendly GROW workflow with undo. |
| Interface | Hardware controls and full editing infrastructure. | Six ambient HOME pages, four musical roles, Bunker colours and note animation. |
| Browser | A web editor, simulator, installer and the MIDI/SysEx protocol already exist upstream. | A focused, modular ambient editor and Bunker’s release website, instrument, guides and tests. |
Compared against Felucca 1.6.1 at the exact source commit used. The base scale table records its 16 entries. This is a description of differences, not a claim that Bunker sounds better or is safer.
Good ideas have neighbours
| Project | What it already explores |
|---|---|
| AMB-1 | Generative ambient, four musical layers, curated pieces, editable scale notes and grow/freeze gestures. |
| Sloop | Three synth tracks plus drums, scales/chords and detailed sequencing with chance, ratchets, nudge and parameter locks. |
| MAKU | Random in-key ambience, four roles and musical macros. Its design removes deep Felucca editing; Bunker retains those editing paths. |
| UnholyUnion | Shared-key ambient arrangements, timed evolution, checkpoints/undo and a browser editor. |
We did not invent generative ambient, musical scales, random walks, undo or a browser editor. Our contribution is the particular library, composition code, musical workflow and presentation. We make no “world first” claim.
