Ah, now I think I understand you - you want to copy, not the patterns but the pattern-tracks (a.k.a. matrix slots) ? This is of course possible.
Similar recording features have already been discussed in this topic’s previous page (hello dby!!).
I think I would settle for an approach which copies any modification in the GRID PIE pattern to the originating slots, and vice versa (bi-directionally).
Edit: Sharing my development roadmap for all the major features that could arrive within the next few versions:
== Streaming output ==
Splitting the output into smaller chunks means that Grid Pie could avoid those dangerous CPU spikes
So, depending on the song’s tempo, notes & automation data output is being written to the pattern just prior to being played.
== Scheduling ==
Because the pattern is being written prior to being played, we are able to support pattern scheduling
(this feature depend on streaming output to be implemented first)
== Multiple-slot scheduling ==
Just like how you can schedule multiple patterns in Renoise, this feature will enable you to
schedule slots: on a grid controller, simply press two buttons in the same row, and any slots in
between will become scheduled
(this feature depend on scheduling to be implemented first)
PS: I moved the posts which dealt with Grid Pie into this thread
