Not quite. Many, Many years ago... I wrote a book with exercises creating composers with pads using the sequencer. The majority of composers don't use all 8 tracks. I would copy the pad into the sequencer then merge into the style you are using in the composer.

Hey Presto! an automatic pad plays with your style when you select the next panel memory. Naturally it will cycle again when the 1st measure comes along, if you don't want this just make the next panel memory the unedited composer with the same registration setup and change to that during the composer duration - thus a single pad accompaniment triggered by panel memory alone.
