AB Compare for Pedalboard Parameter Tweaking

Andrea Del Signore edited this page Oct 19, 2025 · 3 revisions

How to use

Suppose you want to adjust some parameters on a pedalboard and quickly compare your changes with the previous state.

With this feature, when you load a pedalboard, you’ll notice a new A/B Compare section in the upper-right corner of the interface.

This section contains three buttons:

  • A – Switch to the A parameter slot
  • Take – Capture the current state and store it in both the A and B slots
  • B – Switch to the B parameter slot

AB Compare section

At first, all controls are disabled except for the Take button (represented by a “photo” icon).

When you click the Take button, all plugin parameters are stored in both the A and B slots — essentially creating two in-memory snapshots.

After this initial capture, A and B are identical, and the Dwarf automatically switches to the B slot.

Initial capture

You can now start tweaking the knobs while switching to the A slot to compare and listen to the differences.

Switching

You can move back and forth, editing each slot independently and switching quickly between them to hear the differences.

Each time you switch slots, the current state is automatically saved to the corresponding A or B slot.

Once you’re satisfied, you can save the current state to the pedalboard or as a snapshot, just like usual.
