About hardware for live

Hello everybody.

My question is very specific in terms of extreme low latency using it to record and live performance, mixing and mastering it is not priority.

I am amused by the guitar ml plugins and i would like to use it in live performance, for example, neural pi, smart pedal or proteus with some eq and any other effect.

Is that realistic with a raspberry pi 4 with 8Gb ram ? There are a better option with another hardware ?

And hiberry pi is the best option for that? I know the out in that case is on for line but tha could be great also.

Excuse me if that was answered or it was an obvious question i didn’t pull it clear, but i know thera are some videos showing stuff like that but i think, neural pi if i add smart pedal is gonna crash ?

English it’s not my first language i ask apologies also about that.

Thanks for you attention.

Hi Petty and welcome to the forums. A Raspberry Pi4 is certainly enough to run GuitarML with some extra effects. You don’t even need the 8GB version, 2GB would certainly be enough.

I know the NeuralPi (GitHub - GuitarML/NeuralPi: Raspberry Pi guitar pedal using neural networks to emulate real amps and effects.) plugs the guitar straight into the line input of the Hifiberry, that works but I think you would get slightly better sound quality with a preamp in between. Guitars typically prefer a very high impedance input. But any preamp/boost pedal before would do. Even any boss pedal (or any pedal without true bypass and buffered input) in bypass would work.

Thank you so much for your answer Gustav.

In a few days i will receive a raspberry pi 4,

I would like to comment something else, it’s more a comment than another question.

I understand the need of some sort of preamp before the hifiberry, i have soundcard but it is not the typical with usb, this one works with a jack 3’5mm and i thought to plug it on the hifiberry.

It’s called Smart Rigg as yo can see in the picture.

If it doesn’t work i will try some preamp.

You’re welcome! I suspect the Smart Rig is meant to be plugged into a smartphone, or any other device with a 3.5mm TRRS connector and the mic audio is sent on the second ring of the connector, which wont match the TRS connector on the hifiberry, where you’d want the mic signal on the tip or first ring.

Thanks by that info.
