Octatrack FILL Mode - Bug or user error?

[Clancy]

Just plugging my alternate fills approach (though all methods have their pros and cons):

Copy paste patterns without stopping the sequence

Just to make it brief - if the link seemed convoluted: Set master length to 16 but track lengths to 64, then there are three pages on each track that you can work on without affecting audio. Paste them into page 1 when you want to hear them. It’s one track at a time just because you can’t paste on all tracks - but ‘develop’, sure further: “Paste” again at any point to perform an instant undo - i.e… back to original page 1 pattern - good for fills dropped in anywhere ie. this is also the on…
