[sdiy] Varying gate lengths (using a 4017 counter) for a simple sequencer?

[Julian]

Hi there,

I'm messing with a 4017 decade counter, as a simple sequencer.

Is there a simple way to take the regularly spaced outputs (gates) from
this, and vary the length of them - i.e.. both make them shorter then they
actually are, and longer then they actually are?


Basically what I'm thinking is a simple sequencer, like the one mentioned in
the 'simple sequencer' thread earlier, but with control over the gate times
too.

Ken stone's project using this chip offers a solution using switches to swap
between the gate signal and a set, shorter, pulse, but what id really like
is a completely variable time that can also be different for each step,
ideally being able to even have overlapping gates (i.e.. longer then one
clock cycle) although, i guess this isn't nearly as important as being able
to shorten the gate individually for each step.


So, any suggestions? (in relativly novice terms please - im still quite near
the bottom of the curve ;)

Thank you,

Julian
