When I try to add my 257th multi-keystroke chord I get an error saying "Maximum of 256 of multi-keystroke entries. 257 found in chord list."
My understanding was that this is was a limitation of Twiddler 3 hardware and would not be present in Twiddler 4. See for example this archived discussion: Maximum of 256 of multi-keystroke entries [SOLVED] - Twiddler Forum (tekgear.com).
Is this a hardware or a tuner limitation? If tuner, is there a plan to remove it?
