0.2.1 Mar 28
New House Mode for chord generation
A major musical upgrade to the progression engine.
Long press the KEYS or CHORDS tabs to activate House Mode.
Chords now follow house-inspired progressions with richer voicings — including 7ths, 9ths, and suspended chords — along with groove-focused phrasing. Instead of static block chords, patterns now feature offbeat stabs, syncopation, and evolving variation across bars.
Improved multi-bar generation
All randomizers now respect the full CHAIN length.
This means:
• Chords, keys, and drums generate across multiple bars
• Patterns evolve over time instead of repeating a single bar
• Melodies and chords are linked together, sharing the same key and musical direction
The result feels much closer to building a real track — not just looping patterns.
