How to assign the Pioneer RX3 knobs to control stems (vocals, instruments, beats) without a PC?

Hi everyone,

I'm a beginner with the Pioneer RX3, and I’m currently using Virtual DJ where the EQ knobs are set to separate vocals, instruments, and beats (stems mode). I’m wondering if it's possible to configure my Pioneer RX3 in the same way but without using a PC.

I would like the knobs, which by default control highs, mids, and lows, to be set to adjust vocals, instruments, and beats, like in Virtual DJ, while using the RX3 in standalone mode.

If anyone could explain a simple solution, I would really appreciate it!

Thanks in advance for your help!
