Thanks for suggestions. The only way I can work it is to make a very short song sheet say 4 or 8 bars so it is quick to generate the song. Now take a style from Stylepicker and OK so that style will play and you can solo or mute instruments in the moxer. Then call up stylepicker and try another one out. However it is nowhere near as neat or quick as Pipeline's mock-up. I think the developers should bring his mock-up page into reality as this such a cool and quick method of auditioning parts.
