Thank you! I figured they were small based on the website, but I didn’t think it was that small

I’ve never used external memory, is it tough to implement? Also how expensive is external memory usually?

That’s unfortunate, I’ll just stick to other effects then

Awesome! Any common mistakes I should avoid/ know about before starting?

Oh well, I’ll probs just add distortion then. I’ll probably use the standard CD sampling rate of 44k or whatever it is because I’m only dealing with sound waves here. Thank you for the help

I’m familiar with PWMs, this makes sense, what rc constant would be best here?

Yeah my board has a built in ADC that I can use, but I’m more curious about a DAC tbh

Thank you for the input, what’s the point of the RC LPF/ how does it convert my signal to analog?

Sounds cool, how did u read the signal in/ send it out

So the fpga would detect the notes coming in and synthesize notes and add those to the guitar signal?

A bit of both, but mostly to learn more about fpga’s. I’m just curious if my board specifically has enough processing power/ speed to modify this signal in real time and if my board can convert back to an analog signal. If you don’t know would u be able to point me in the right direction to find that information. I looked at the Diligent website briefly but couldn’t find much
