Hello.
Just a question about this dac: https://www.hifiberry.com/
I know that this is far more expensive than a cheap usb dac, but would it work with sampler box?
Some modifications required? Not at all?
Best Regards,

Hi André,
I really think it will work, because it will be recognized by Linux as a standard audio device, which can be used by SamplerBox. (But I never tried myself this DAC, so I cannot confirm 100% that it will work).
The only problem I see with a DAC connected as a hat on Raspberry Pi's GPIO is that the GPIO pins are not free anymore! And we do need GPIO pins for:
Now that I looked at the pictures of these DAC mounted as a hat, I see that I might be possible to add pin headers on them to replicate the GPIO pins? Never tested myself...
Anyway the 6€ DAC is really excellent, it is based on a good Texas Instrument PCM2704 chip (and I compared to lots of soundcard audio outputs), that's why I didn't investigate more on more expensive DACs.
GPIOs on the DAC can be used also for buttons and stuff if you make sure you don't use a GPIO that is in use already. These are documented here;

Hi Joseph,
Thank you for your reply. I have been out for a while and only now I was able to respond you.
My question was focused on how "easy" would be to build your project with different parts (as I live in Brazil, sometimes you can't find all you want). I found your DAC recommendation selling on Amazon, but the seller does not ship to Brazil.
I have this wack idea of assemble a harpsichord mockup using keys from a local luthier but putting a samplerbox inside, instead of hundred brass wires, felt and wood pieces.
My wife plays several keyboards (harpsichord among them) but we can't afford to buy (and specially maintain) a real one. As I said, just an weird idea...
By the way, GREAT PROJECT - many thanks for sharing!
