3.2.11. Nth1 and Nth2

Parameter layers Nth1 and Nth2 allow you to create long variant patterns which change based on
mathematical rules. Nth1 will trigger the specified action the first time and then each nth bar, while
Nth2 will start triggering only after n bars, and then each nth bar.

The possible actions are: 1. Pl: Play each nth bar
2. Mu: Mute each nth bar
3. Ac: Accent each nth bar
4. Ro: Roll each nth bar
5. Fx: enable Fx each nth bar
6. Nx: disnable Fx each nth bar

The first selectable “operation” (– 2 etc.), before Pl, is actually a dummy value. It does nothing and
can be ignored. The final operation (“?? 1” etc.) is currently empty, and also does nothing.

Below is an example sequence and how it will actually sound. The operation for both steps is “mute”,
and because the parameter is Nth1, muting starts immediately from the first occurrence, and then
repeats every second (for step 2) or fourth (for step 4) time.

            step1     step2     step3     step4
note param. layer   C-3       D-3       E-3       F-3
Nth1 param. layer   ---       Mu2      ---       Mu4

This is the actual outcome of the settings above:

            step1     step2     step3     step4
note param. layer   C-3       ---       E-3       ---        first iteration
note param. layer   C-3       D-3       E-3       F-3        second
iteration
note param. layer   C-3       ---       E-3       F-3        third iteration
note param. layer   C-3       D-3       E-3       F-3        fourth
iteration
note param. layer   C-3       ---       E-3       ---        fifth iteration

With the same settings but with Nth2 parameter, muting would start only on the second time the note
is played (for step 2), and then every second time (for step 2) in the example above. If the Nth layer
was Nth2 instead of Nth1 in the example above, the outcome would be:

                    step1     step2     step3     step4
note param. layer   C-3       D-3       E-3       F-3        first iteration
note param. layer   C-3       ---       E-3       F-3        second
iteration
note param. layer   C-3       D-3       E-3       F-3        third iteration
note param. layer   C-3       ---       E-3       ---        fourth
iteration
note param. layer   C-3       D-3       E-3       F-3        fifth iteration
