25 Utility Pair

By Chris Johnson

Utility Pair splits the card into independent left and right utility engines. Each side owns one knob/control and one column of input/output jacks, letting two utilities run at once. In the 2025 multi-pack firmware, hold Z down at power/reset to enter utility selection mode, then choose left and right utilities and start. Specific jack behavior depends on the chosen utility pair.
