Hi Wishbonebrewery,
I am not fully sure what you mean with no-HP modules, meaning you want an external solution? If that's what you mean, nothing pops up in my mind.
If you don't mind to consider a Eurorack module, then Make Noise - X-Pan module comes to mind but that's it, I think, not too many options out there.
Good luck for the search of this solution, please let me know if you found something, I also might want something into that direction and kind regards, Garfield.
