I really like the pattern chaining implementation added in version 1.3. In particular, being able to put a separate chain (or simultaneously enter the same chain) on multiple sequencers is wonderful. There is just one bit of odd behavior with certain settings that can hopefully be addressed:
I have "Wait to Load Pattern" set to "On," so the pattern should change at the end of the current measure. If I stop the sequencer and create a pattern chain, then hit 'play,' it will always play the currently selected pattern once before beginning my chain from its beginning.
I can imagine why this is happening, but it's musically undesirable (and doesn't match other step sequencers' chaining behavior,) since frequently you'll enter a pattern chain and hit 'play' to start a song. This makes it sound as though you've entered an extra loop of the currently selected pattern and that you've done your chain incorrectly. It also throws off looping songs, which you'd like to start at the beginning of the chain you've entered. It's unfortunately exacerbated a bit by the fact that you also can't change the pattern without wiping out your new chain >
For example, if I'm on pattern 1 and set up a chain as: 1 1 2 2 3 3, I'll get: 1 1 1 2 2 3 3 when I hit play, and when it loops it will be 1 1 2 2 3 3.
