The Next/Previous menu item has a hierarchical sub-menu with four sets of commands corresponding to the four important elements in a FreeStyle song: sections, players, takes, and sounds. In each case, the next/previous command moves to the next or previous item in the list. If you are at the end of the list, the Next command cycles you back to the beginning of the list; likewise, if you are already at the beginning of the list, the Previous command brings you to the end. This lets you cycle indefinitely with either command.
(1) Next/Previous Section
If you are currently viewing a single section, these commands will cycle through all of the currently defined sections in the FreeStyle document. If you are currently viewing a song arrangement, they will cycle through only those sections which appear in the top row of the arrangement grid in the arrangement window.
(2) Next/Previous Player
Cycle through the list of players in the Ensemble window.
(3) Next/Previous Take
Cycle through the list of takes for the currently record-enabled player in the Ensemble window.
(4) Next/Previous Sound
Cycle through the list of sounds available to the currently record-enabled player in the Ensemble window. For General MIDI devices, you will hear a beep before cycling into drum sounds. That’s to alert you that you are about to change the drum sound on channel 10, which could cause your Riff Metronome to stop playing correctly if the Riff Metronome is using the same output device.
