I am trying to create square waves with specific lengths of pulse width.
I think that this tool is the best option. I have read the passage in KymaX about it.
I thought I had the concept down, however once I start modifying the values, It ceases to entertain my experimentation.

I took a wee 22k jpg of the parameters I had used, but it won't let me upload it.

SO..

Duration = total length in s or samp

Points : 0 1 1 0 (Start, Full, Full, Stop)

Segment Proportions: 0 1 0 ( we have one less of these than the number points!)

What am I missing?

Many thanks

Charlie

Hi Charlie,

I think it is choking on the 0 as a segment proportion. Maybe if you use something very small in place of zero, for example:

Points: 0 0 1 1 0 0
Segment Proportions: {1/3} {1/4096} {1/3} {1/4096} {1/3}

Ohh Nice, curly brackets!

Next problem;

I can make it 1 s = 1000 ms! Great, 0.1 s gives you 100ms

My goal = 10 ms = 0.01 s
Does not seem to allow me to create it.. I think this is to do with the values in the segment proportions. Mmm still missing the conceptual link here somewhere.. samples vs ms i guess the segments expressed in samples would breach the total length.... errrr

Just for a bit of context...

I am firing the pulses from my daw, I have it all working, but (as the video explains) the length of the pulses is important, i guess I should try to make a sequencer in kyma for it.

Many seasonal thanks for your never ending support.

Could you use the PulseTrain Sound in Kyma? Specifying Period as a duration and DutyCycle as a fraction of that duration?

Or a triggered FunctionGenerator with live control over the Duration and SmoothedRectangular as the waveshape?
