ForumsSoftware ← pitch signal output question

Just reading through the manual about the pitch output in key section of Aalto and see the following.

"When MIDI note C4 is played, the pitch signal
output is 0. This has the same result on a patcher input as when
nothing is connected."

Any idea why in my case it's A3? C4 influences the parameter either positively or negatively depending on the signal input setting. A3 gives no signal modulation as if nothing was connected.
No matter how I set the keyboard (novation remote 25SL) I get signal output 0 when press A3.

Tuning is set to 12-equal if that makes any difference.

Any idea why it works that way?

A3 is the real center. So there is a bug in the manual. Thanks for pointing this out!
