Hi you all.
Never tried the mod trick, until today, and it did not work.
The only thing I can say now is  mea culpa, mea culpa, maxima culpa.
Never believe annything before you've tried it your self I guess.

I got it from a synt repair tech back in 1987, and never doubted his
The theory was to have a sine one octave below the square and mix the result
with the square.
i.o. 1*(2,4,6,8,...) => (1,3,5,7,9,....)
It should explain why the D50 saw gets all kinds of holes in it when the
pulse width value is not set to zero.

As said I tried it to day, the results where intresting,
but Paul is right, it never produces a saw wave.

Just hope I don't have to put on some concrete shoes for this one
(you know go for a swim and stuf like that).

Cheers Theo.
