Hey there,
I’d like to suggest a small but very useful feature for the Hapax: adding a tuner that works with the CV input. On the Hermod+, this feature is extremely handy for calibrating oscillators or checking pitch, and it would be great to have the same functionality on the Hapax as well. Since the Hapax already has CV inputs, integrating a simple tuner could make patching and tuning analog oscillators much easier, especially in hybrid setups.
Thanks for considering it,
Cheers,
Tom
Seconded!
I would also like to request a tuner for the cv inputs, like the hermod+ already has. Although, I imagine that function will definitely be implemented once the official xp32 cv expander support with upcoming adapter/interface module release. 
Do you have insight on this being a real thing?
Yes. I recently messaged Squarp to ask about it, and they confirmed that Xp32 cv expander native support is coming to Hapax! It will require a new upcoming module to connect them together (without the need for Hermod+ in the system).
I imagine the module will probably have a port on the front for Hapax to connect to, then the Xp32 ribbon connects to the back. Hopefully, they are able to somehow add a few more cv ins on the front panel as well (since xp32 has 32 outputs, but no cv inputs).
Regardless, once the extra 32 cv/gate/pitch/mod etc outputs are implemented, it will definitely make Hapax the most powerful eurorack on the market imo. Cant wait!
I posted a topic here about the conversation I had with them here: XP32 cv expander compatibility definitely coming soon
