Hello,
If you use the “P Act/Byp (M)” option, this will allow you to send separate active/bypass messages depending on the CC value (0-63 will be bypassed, 64-127 will be active). This should resolve the issue of toggling when you want to bypass both presets. More information can be found here: https://cdn.eventideaudio.com/manuals/h90/1.3.0/content/appendix/global.html
Let me know if that works.
