This echo/delay module uses external ADC, external DAC and external RAM (2Mbit)
This video is proof of concept, the ADC is very noisy (no filters used at this moment) and I use external modules for feedback.
I plan to add a filter, feedback added to the module and figuring out a way to use this module as a sampler. I will probably add a hold switch for that...
And a trigger/gate input for if I use this as a sampler, I can trigger/gate the replay.
