TB303 quickie question and EG findings...

[Tony Allgood]

Hi,

I am wondering why the TB's accent control signal is controlled by the
slide control. The accent logic signal comes from the output of a D-type
flip flop, the rising edge triggered CLK is the slide control (high to
slide), and the DATA IN is coming off the control board. Anyone know why
there should be a d-type there??

The TB's EG is very interesting. The output to the VCF is the usual
exponential fall, but the odd thing is if the gate arrives before the
cap is discharged the output rises higher than before. If multiple gates
trigger the EG the output CV can be very big. mmm... there really is
more to this beast than I first thought. I like it.
