Something you can do with almost any synth is appropriate a standard MIDI source parameter as your “macro.” For example, Digitone, like many modern synths, allows sources mod-wheel, breath, pressure, and aftertouch to be assigned to multiple parameters. Since you’re likely not using breath as a source, that can be your “macro.” Assign up to 4 parameters (max on Digitone) and send automation to CC2 from the Hapax. You can do the same with mod wheel if you’re not using one.
