Subject description: How to do this without a filter phase module.		 Reply with quote  Mark this post and the followings unread
Hi Guys,

I really love the StringVariations patch it works very well with a midi guitar, and I would like to try creating this patch on some other synths.

From what I can see the sound is being created by the the Filter Phase module being frequency modulated by an audio signal.

I have had a hunt around to try to work out what this module actually does (in idiots terms) and am having some difficulty, can someone give me some pointers to what this module is actually doing and how you could get this effect without a module like this?

Thanks once agin for any help.

Andy

Sorry, lazily I had hoped Rob would have jumped in Very Happy

Meanwhile, from the help file :

Quote:
This is a 14-pole phase filter with peak spread control and adjustable feedback. It features six allpass filters which displace the phase 180 degrees each. It is possible to select the number of allpass filters (1-6) to be used, giving from one to six notches/peaks.


So its allpass filters with feedback, so just an "ordinary phaser" without a builtin LFO. The spread probably works by spreading the "resonabce" frequencies for the allpass elements. Not sure how the "type" control is done, I'd think it to be some trick with signal inverters, but that's just a guess really.

Hey Andy

I read your post but have long since overwritten a lot of the factory presets, including the one you mentioned sorry.
