Hi @nicklovn – a belated welcome to the forum, and thanks for your post.
In Scaler 3.1.1, ‘Scale White Keys’ Keys Lock mode now sends Mod wheel data.
The update is available now and includes a range of improvements and critical fixes. We strongly recommend it for all Scaler 3 users. You can download the 3.1.1 installers from either Plugin Boutique (under My Account) or Scaler Music (under My Products).
For full details, check out the latest version thread for the changelog. Cheers.
