G081 Audio

Maker	Eric Brombaugh
Type	Reverb module running the Alesis MIDIVerb algorithms on an STM32G081
Mounting	SMD
Width	6 HP
License	Proprietary (MIT covers the code, no hardware grant)
Difficulty	🌋 Fine-pitch SMD

Clone of Alesis MIDIVerb reverb algorithms. Grew out of the maker's MIDIVerb reverse engineering project. The algorithms are compiled to C rather than interpreted so they fit a 64MHz Cortex M0+. PT8211 I2S DAC, a 64x32 OLED, two CV inputs and stereo audio in. No gerbers are published.
