Problem all solved. Bought a stereo DI with mono line and instrument out. Which will come in handy sending soft Synths to an amp as well as my piano.
Many thanks to Happyrat for getting me to look at direct boxes in the first place. Never would've thought they'd have the stereo to mono market cornered
