I've got a KN930 that I'm trying to come to terms with.

The manual details are a bit sketchy and I'm trying to work out if I can add to a One Touch Play recording.
If I record a song using One Touch Play is it possible to hold this in the Sequencer and then add another track (instrument) to it?
Can I do this if I have used Easy Record to make the original recording or do I have to use the Sequencer from the start?
Is it possible at all?
This probably seems fairly basic stuff but I guess we've all got to start somewhere!!!
