Re-triggering effects

A fragment's 'rEtr' parameter governs how (if at all) the chosen pattern's steps should be re-triggered.

Having a pattern re-trigger for the duration of a fragment, can quickly and conveniently create fills, stutters or variations without having to change the pattern itself.

The following re-triggering types are available;

• 'OFF'; re-triggering off. No re-triggering.
• 'Loo.1'; keep looping/repeating step 1 (keep repeating step 1).
• 'Loo.2'; keep looping/repeating step 1 and 2.
• 'Loo.4'; keep loopoing step 1 through 4.
  
• 'Fill'; play step 1 through 12 as normal. Instead of playing step 13 through 16 as normal, play step 1 four times.
• 'Stu1; stutter 1 step duration (e.g. play step 1, play step 1 again, play step 3, play step 3 again, play step 5, play step 5 again, etc.)
• 'Stu2; stutter 2 step duration (e.g. play step 1, play step 2, play step 1 again, play step 2 again, play step 5, play step 6, play step 5 again, play step 6 again, etc.)
• 'Stu4; stutter 4 step duration (e.g. play step 1 through 4, play step 1 through 4 again, play step 8 through 12, play step 8 through 12 again)
• 'rvSE'; reverse the pattern. Plays the pattern in reverse, starting at step 16.
  

All re-triggering effects assume a step length of 16 steps for each pattern.

All options have a second variant (with a dot/'.' at the end). This variant will, at the end of the relevant playback time, apply a note off and a hard mute. This mimicks a sample-based buffer lock, making sure that notes don't ring out.
