You can replicate anything achieveable with playlists, though if you have a
playlist with the same pattern used on a number of steps, with different
transpose values on each step, you would need to use duplicate bars to
achieve the same thing in a v4 pattern.
But unless you make heavy use of that, it shouldn't be a problem with the
improved flexibility of dynamic storage.

So far there are 255 bars of storage space because I'm only using single
byte pointers to the bar storage.
I will be extending the pointer size to 2 bytes soon, which will allow the
maximum available RAM to be used for bar storage.
Ultimately the current P3 hardware will be able to hold at least as many
bars as there are currently patterns, possibly a few more.
Though I do have a scheme to add memory paging on a RAM daughterboard that
would allow over 3000 bars storage.
That would depend on demand though.
