Stereo bouncing

Hello everyone, I’m new to the op-1 and have tried the 2 bouncing methods, one via lift all tracks and place in the Sampler, and the other way via recording to the album then listening using ear and re recording to tape but both methods result in a mono recording, is there a way to stereo bounce?

Just realised all tracks are mono until they are recorded to the album arggg oh well mono bouncing it is then lol
