What's New in Patch Assist
1.2
August 11, 2026
Fine-tuning a DMX address is now faster and clearer: • Step by ±1, ±10 and ±100 — jump across big address ranges in just a couple of taps. • Cleaner button layout: plus on top, minus below, matching values aligned in columns. • In the patch list, just tap a fixture's address to instantly show it on the DIP switches. • Fix: the bottom tab bar no longer shifts up with the keyboard while typing.
