I was wondering how replacing the 150MIPS 56367 (https://www.nxp.com/docs/en/user-guide/DSP56367UM.pdf) with a 56MHz Cortex M3 (https://gd32mcu.com/data/documents/data ... Rev2.8.pdf) resulted in usable processing power.@Rwedelich
Eventide Dev here. I'll only comment on what you got wrong about the processing power b/c I don't want misinformation out there. It'd be amazing if we could squeeze all that DSP math out of a 108 MHz chip, but alas, that's just not true. The GigaDevices chip is not the main processor. It's just a board micro controller, and in fact, there are two of them in the box. The main event is an NXP imx8 mounted under the audio board. It's a quad core Cortex-A53 1.6 GHz per core processor (with additional Cortex-M4 coprocessor). The manual is like 4000 pages long. I DO NOT recommend you disassemble to access it b/c of the risk of damage to the unit.
