Same with Roland...

Set a transposition, engage 'Hold' change anything you want and the t'pose stays on.

Plus, every now and again I get a guitarist that likes to detune a half step. There's a Global Transpose in the Tune master page that is independent of the front panel t'pose, so you can drop down a semi or whole tone (-6 to +5, actually) and still use the regular transpose buttons as well... Take Hold off, and the Global T'pose still is in effect.

Best of both worlds...
