If it's a stereo piano patch with stereo reverb already added at the keyboard then record in stereo. Examples: If it's a lead synth you plan to pan and add stereo effects to later then record in mono. It all depends on the patch you are using. He had a Yamaha keyboard, around $1200, it had two outs, mono or LRĭid I miss something here.
Just did a recording, see Dolphin Dance in the songs forum
