Anyone using a PiPedal?

[tauzero]

Is anyone experimenting with a PiPedal by any chance? Just wondering whether to spend a bit of time putting together something else I won't use.

I looked at this before and it seemed a well thought out project. Sensibly the dev used decent and separate USB Audio hardware and a Web interface. 

 

If you have decent usb audio hardware and a pi already, I think it could be a cheap and quick project. The software looks OK as well. I've got the parts just sitting here doing nowt (by chance and not by design) but not really wanted another project to work on. 

 

I didn't look into the build tool chain to see what was needed but assumed it would work. 

 

I already have a ToneX and a mod dwarf so another modeller seemed overkill for me, especially as it had a separate USB interface, which might be an advantage to some people. Most pi projects seem to use an audio hat and these don't have the quality IMHO. 

 

Go for it, I'd be interested in how it works and sounds.

And to really mix things up as well

Never built either StompBox or PiPedal. StompBox gets some great writeups from people.

 

Perhaps a winter project over Xmas?

Tried the PiPedal on a Pi 5 with a Hifiberry DAC+ but it didn't want to know - not sure why, as I did the correct config amendments and it shows up in aplay. However, from the discussion forum it looks like USB interfaces are the recommended way forward, so I've decided not to waste any more of my life on that - it'll get put to other purposes. I've got a Presonus Studio 24c incoming to play with so I don't have to start unwiring the other USB interfaces I have littering the house. More news next week sometime.

Presonus Studio 24c connected to Pi 5 and recognised straight away. Configured to 48kHz sample rate, 64/4 for buffers, showing a latency of 5.3mS. Now I've got to work out how to connect something up to the input and the output, with everything precariously balanced on my desk and my chair occupied by my circular saw until I can get the new blade for it and take it back to the shed (the floor is fully occupied). Things will get better once Mrs Zero gives me the go-ahead to move into Sub Zero's former room.

How have you stolen my desk and all my stuff?  At least it's now tidier than when I had it.

Might be a stupid question but how does audio out work? You connect the USB interface to the Pi for input, are you then limited to the audio out jack from the Pi for output or can you configure the app to send audio to USB which you can then connect back to your DAW PC, essentially using the Pi as a pedal? The documentation doesn't seem to answer it or show a signal chain, and all the setup pictures just seem to show the USB input and power connected to the Pi....
