I am confident that a monome module designed specifically to interface with Arc4 will make an amazing use of the Arc witmhout the need for push-button functionality.
When writing some patchs in Max for the non-push Arc4 I often wished that the push option was there, but with the module counterpart, additional functionality can be built/integrated with the Arc. As in: for example (and totally hypothetically) 4 gate inputs on the module can easily provide what pushing on each of the 4 knobs would have done…
