Yeah that's by design, and kind of a nifty byproduct. The demo tune on the landing page was actually generated by the DSP engine running on macOS. For me, it's mostly a development aid but you can use it that way if you wanted.
Just wasn't part of the motivation. I wasn't looking for another standalone macOS app or VST. Wanted something tactile (controller I already have muscle memory with) and a touchscreen UI.
I certainly don't mean to minimize the work - you've done a fabulous job! I went off to find the hardware to assemble and the prices are kinda nuts... It's awesome having the option to run it on something I already have.
