[NTG-context] Possibilities for basso continuo figures in a text-line disappeared?

Hello, The code for including basso continuo figures in a text, added somewhere between may and august this year: \definelow[MyLow][style=\txx,frame=off] \definehigh[MyHigh][style=\txx,frame=off] \definelowhigh[MyLoHi][style=\txx,frame=off] \definelowmidhigh[MyLoMiHi][style=\txx,frame=off] is unfortunately no longer recognized in the minimals I installed today (29-10). They still worked in august (25-08). Have they been changed or accidentally deleted from the source? Could I have them back please? Thanks in advance. Best regards, Robert Blackstone
