Problem with bit changers in control presets

Question

MIDI Target Manufacturer(s): Other/Unlisted Maker

I've got the following simple layout

Super A - button - bit changer, change bits 1

Super B - button - bit changer, change bits 2

These are both super controls of:

Sub - Knob, values 0-3, MIDI cc

In play mode this all works fine, and I can see the correct MIDI messages in the log

I can't get these to work correctly with a preset control, ie. I set up a simple preset control with store/recall buttons

Visually, everything works ok when recalling presets in this simple setup but the MIDI messages are all wrong.

For example, with both buttons off, if I recall a preset with both buttons on, I get two messages, first with Data2=001 and second with Data2=000

Even if by some chance the first message has the correct data its always followed by a second message with Data2=000

I've tried various things like using sysex instead of cc in the sub control, re-ordering subcontrols in the preset control, etc but can't get this to work... help!

Ignore this! Bit changers weren't what I needed!

Looks like a momentary button sending both on and off values.  You need to enable "send on only."  But as you say, there are few real uses of the bit changers.
