Intro/Ending looping
Main sections reordering
The current section (the one that is playing if the sequencer is running) is highlighted. The next section (that will play at the end of the current one) is identified by the flashing led. If a section loops forever (i.e.: a Main) then the led will flash on the current section (the playing section is the successor of itself).
If no further button pushing happens, an Intro will play till the end and then automatically leads to a Main (the target Main has the led flashing). An Ending will play till the end and then the sequencer is automatically stopped (no led flashing anywhere).
A Break will return to the playing Main (or will end a playing Intro or Ending and will lead to a Main). A Fill will lead to the Main section at its right. Sometimes a Fill is automatically inserted before a Break or Ending, where musically appropriate.
A new section will usually takeover at next measure start (you can therefore select it in advance); Breaks and Fills instead play immediately till the current measure end. If you play a Break or Fill very close to the measure end, the Break/Fill will start at the next measure start, playing for a full measure.
With the SYNC F/B (sync fill/break) button you can force the next Break or Fill to always be delayed until next measure start (and play for a full measure). The SYNC F/B button will automatically disengage itself when you play a Break/Fill. It must therefore be selected each time you need it.
You can move from Main to Main without a Fill (just press the new MAIN button), or with a Fill (press the FILL button corresponding to the Main section you want to go to). A BREAK/FILL button will always lead to a Main section with its note pattern played from its beginning. Keep reading to see how you can override this.
Clicking a MAIN button while it is already playing, will trigger an automatic Fill till the measure end, but will not reset the playing loop to its beginning. This is sometimes useful to spice up your execution without interruption of a musical phrase.
This is called an "inline fill" and it is often triggered also through the velocity of the played chord. See here for a detailed explanation of how to set up this mechanic of interaction.
