Felucca Sequences

Firmware for FM-1 (M-VAVE)

Felucca 1.5.1 fork with eight selectable sequences per track, optional chaining of them into longer runs, and per-sequence song choices, at the cost of the user sample slots.

Description

The sequences are stored in the flash that the three user sample slots used, so these builds have no user samples. A track plays one of its eight sequences, chosen on a SEQ page or with keys while SEQ is held, and can switch at once or at the end of the current pass. Chained sequences play in order, and a song cell can name which sequence it plays. The repository was renamed from Felucca_8_patterns; the README is Felucca's own with a section for the added feature at the end. The author says the changes were written with a free LLM.

Install notes

The project page forwards to the Felucca web installer in the repository (Chrome or Edge, USB), and the release carries a felucca-1.51.fwsc package. Projects saved with sequences may not open on firmware without them.
