First recordings of POP through a Fender Blues Deluxe 40W A/B tube amplifier. Camera is a GO Pro HERO. The amplifier is looking towards the wall in order to save our ears. Guitar is a Yamaha Revstar 420, I love it.
Sound quality looks promising, though still I can hear some computing noise, specially when configuring a compressor or a distortion/overdrive. When using delay type effects, or reverb, noise is quite bearable.
I am using a 512 bytes buffer, and getting around 20ms of latency, still too much.
Some more research is needed to get the best from this unit, keeping in mind the limitations: CHIP board works at 1GHz, and sound card is integrated in the SoC, as long as I know.
Stay alert for new tests.
I have also still to publish some documentation about the project. More details can be found here: https://www.hackster.io/manolonte/pop-programmable-open-pedal-9acddf
