Synthstrom Deluge Firmware Now available as Open Source

Synthstrom Audible has announced that the Deluge firmware is now available as open source.

The Deluge is a grid-based instrument that’s a portable sequencer, synthesizer and sampler. It features 128 RGB pads, arranged in a 16 x 8 grid; a built-in synthesizer; up to 12 minutes of sample playback from SD card; and sequencing of up to thousands of notes.

What they say about it:

“The Synthstrom Audible Deluge Firmware runs on the Deluge portable sequencer, synthesizer and sampler, produced by Synthstrom Audible Limited.

The Deluge Firmware’s codebase is written mostly in C++, with some low-level functions in C, and even the occasional line of assembly. The program is “bare-metal” – it runs without any higher level operating system.

The firmware runs on the Synthstrom Audible Deluge’s Renesas RZ/A1L processor, an Arm® Cortex®-A9 core running at 400MHz with 3MB of on-chip SRAM. The Deluge also includes a 64MB SDRAM chip.

The firmware is built using a GNU ARM Embedded GCC toolchain.”

Two online events are also planned to introduced the open source project:

  • Saturday, June 10, 11am, CEST – Open Group Zoom session with Rohan. Will be recorded and made available on the GitHub following.
