Multiple synth layouts: updated to the latest slider script. (#13422)
* Explicit configuration: Using add_* functions, instead of scanning through the layout for sliders. * Separated the copy-pasteable portion of the script. * A no-op for the DMX and LinnDrum layouts. * Fixes multitouch and slider "drift", and adds support for relative adjustments to the D70 sliders (they were using an older version of the script).
