hmm everything should work with default settings on the minitaur. Can you try saving your current A4 project and doing an empty reset of your machine and re-setup the cv tracks? Also try doing a factory reset of your minitaur, if it wasn’t brand new who knows what has been tweaked and saved through the editor.

Also do you have any other gear you can try sending a CV signal to? If you are getting proper v/oct output from your cv tracks to another device then you know for sure something’s up with the minitaur.

also do the same sending midi notes to the minitaur to confirm the oscillators are working OK.

You should be able to isolate where the problem lies after this
