It all depends on what you want to do. I usually centralise the Pan for each track and set the Volume to show about -6db on the VU Meter to avoid clipping. The Ketron sound module sets default effects for both Reverb and Chorus and these will be included in your recordings. If you wish to record dry tracks and then use DX/VST audio effects on the resultant Wave tracks at a later stage then open the Mixer, find the "ALL" Column and reset the two radials at the top of the column from 127 (default) to Zero. Note that these settings will remain until manually altered.
