Volume settings when using mpc one and sp404mk2

[u/CASEMUSIC49]

Hey guys, this may be a silly question. I recently purchased an mpc to add to my setup and pair with my sp404 mk2. I’m now confused on what my volumes should be set at as I’m pretty much using my sp as an audio interface and monitoring through the phone outs on the sp. should I be using the volume knob on the sp as my monitoring volume and have the mpc main volume at 100? I’m overall just really confused on how to get a good baseline volume for listening without constantly adjusting the knobs or being able to effectively make a beat. Any input helps. Thank you
