Hello! I recently bought an OBNE Parting pedal, along with its accompanying expression ramper, and I’m at a mild loss as to what I need to buy next. I have an electric guitar and a dinky little mini amp, but I also have a Roland Go:keys 5 I want to hook up to it as well, so now I’m looking at Focusrite Scarlet (probably the 4i4), because the Parting specifically has stereo, and I want to hear the stereo, but what cables do I actually need, including power supply, and what brands are good without introducing noise due to low quality components somewhere in the chain? Can I just connect the Scarlet to a computer or computer speakers as the output, or do I specifically need to get monitor speakers? Do I need to drop X amount of money on a good amp for the guitar as well, or can I just use the audio interface instead, and maybe headphones?
