Add the “Play N/Skip M” and “Skip N/Play M” as step effects on the Tracker as explained in the Play manual (Polyend Play - Manual). This should be very easy to implement and will be a great enhancement of the Tracker.
What is the problem?
These effects are not currently available on the tracker and would expand the flexibility of Tracker tracks.
What do you want to achieve?
Are there any workarounds?
Yes, to some extent by creating longer tracks. Or copying patterns and changing the few parts you want to skip/play.
