controlling pattern changes with Octatrack, to Digitakt
To get Digitakt to receive Pattern change from the Octatrack, make sure your auto-channel value is set to the same number on both devices. Leave the auto stuff on "auto", it seems to work as you'd expect with that on. Haven't managed to get it to work using the standard midi-message sends yet though... Digitakt seems more ready "out of the box" to send pattern changes as the boss.
