Hello Florian,

the A-196 is not the right tool for clock multiplication because the A-196 VCO works only in audio range. But the new A-160-5 clock
multiplier will be the right choice. With the control knob you can adjust the multiplication factor (static application of the
module).

For a reliable and clean frequency multiplication in audio range divider and PLL should be on the same board (like the high speed
VCO of our old sound sampler) as the PLL circuit used in the A-196 (CD4046) is very touchy. There are plans for such a module
(A-196-2 with on-board divider) but I have no idea when it will be realized.
