I want a new A4 pattern/kit etc with pattern/part change on the OT. Reading the OS1.1 spec it seemed the mappings were a neat way to do this.

Doing it in the old way has never worked for me, where changing from A01 to A02 on the OT triggers a similar change on the A4. It just doesn’t work, despite rigorous review of MIDI settings in both boxes! And anyway my existing OT projects don’t lend temselves to this 1:1 correspondence in the pattern numbers. I was very pleased when I read about the mappings in the update - I thought I’d be able choose which A4 patterns were called as a song progressed. Sounds ideal!

My programme change pain with other synths had a similar objective, only the note data was all in OT MIDI sequences. It was simply unreliable - I could achieve programme change with the Virus, but half the time it just wouldn’t work. I’m used to the idea of pressing Play and the right sounds all coming up on external synths, and doing so predictably. But sometimes it would and well, sometimes it just wouldn’t!

I don’t know whether OS bugs are responsible for all this or whether it’s me.
