SpinCAD servo flanger center delay time

[changes]

Hello

Lately I am tinkering with SpinCAD's servo flanger block and I like it a lot but I would like to be able to change the center delay time

Any advice if that would be possible?

What is it that you are using to modulate the delay time?

I set it up with a ramp LFO with a volume to control depth

Take a look at this and see if any ideas come to mind.  Let me know if you give up.

Thanks for sharing that link, it helped understand a bit more on what's going on the LFOs but I think I'm still kinda lost regarding my issue

I get a nice modulation the way I have it set up but I want to change the center delay time.

For example I know that flangers have a delay line that gets modulated (I believe it usually is between 0-6ms)

I don't know what the unmodulated delay time of the servo flanger is, I mean how many msec of delay you get with zero depth of the LFO

I'd love to find out and if possible change the unmodulated delay time into higher values so I would be able to produce chorus and / or vibrato sounds with the LFO engaged

I don't really know how the control input maps to delay time either.  What I would do would be to take the 0 - 0.5 triangle output as you have and then run that into a scale/offset block.  You want the range 0 - 0.5 to map to -0.25, 0.25 (SOF 1.0, -0.25).  Run that through the multiply.  Then you want to add this to the offset, say, from a pot.  Use a 2:1 control mixer block to do the addition.  The offset would have to start at 0.25 so we don't send negative values into the servo delay's time input when the width is up full.  So from the pot, run it through a scale/offset mapping (0,1) to (0.25, 0.75).  That also leaves 0.25 on the top end.  Quite likely you will have to adjust all of this (and the servo gain) interactively.

This at least gets you to where you can set a fixed offset and then have the triangle scaled by the width control wobble around it.

Does that help?

I don't know if I got this right but do you mean something like this?

Anyone else care to take this one?  I've been busy job interviewing and doing a small amount of contract work, sorry I have not been back to answer.  Part of the delay is my desire to set things up to make sure what I'm telling you is true.

No rush at all. Feel free to get back to me whenever time permits. I will also try to work it out during the holidays

Merry Christmas
