Control Changes

Usually M+O will try to follow the soloist, however, you may wish to override this behavior and have the accompaniment ignore the soloist during a certain passage.  For instance, this may be desirable when the soloist plays an secondary "accompanying" part.  You can set control changes either from solo to accompaniment, or from accompaniment to solo on the Set Tempo form. 
  • "To Accomp" control changes exchange the leadership role from the soloist to the accompaniment.  The accompaniment will ignore the soloist's playing after such a Control Change. 
  • "To Solo" control changes revert control back to the soloist.  After such a Control Change the soloist is in control again.  

    It is not necessary to insert a control change when the begins playing an "accompanying" part.  In such a case you can think of the soloist as playing the role of the conductor --- even if the soloist's part is not important, someone needs to lead.  Even though many musicians may not want to lead while playing a secondary part, this generally gives the best results with M+O. 

    During a section beginning with a "To Accomp" control change, the ensemble's tempi and other timing issues will result from any tempi you have set, as well as the initial training of our timing model.  This initial training, performed before you install the piece, is learned from the accompaniment-only recording distributed with each piece.  Thus when M+O is not trying to follow you, it will revert to the tempi of this original performance.
