I cannot change the number of voices if I run any Creamware-Synth in XTC-Mode. If I double-click in the window which displays the number of voices, the value changes to 9 (which is too many). If I double-click again, it changes to 1 again (which is not enough). If I click only once, nothing happens. I cannot change by typing another number, typing the backspace-key or the delete-key.
Does anybody have a solution?
