Modulated Verb in Spincad

I'm really enjoying the exploration part of SpinCad! I have been able to create some cool sounding effects and have a couple real killer verbs. The only thing I can't figure out is modulated verb. I have tried adding a chorus block on the output of a verb block, adding chorus in a feedback loop, etc, but I still can't get anything decent sounding. I'm starting to wonder if I know how to use the chorus blocks correctly. Do you need to feed them an lfo or are they self contained?


Also, is there a list that outlines what all the design blocks do? Any help would be awesome. Thanks

You should probably look through all the reverbs at Spin's "free programs" and in the different projects they have, like "OEM Mixer".  Most of these have some sort of modulation built-in.  Look for "CHO RDA" in the code, it's a dead giveaway.  I've seen a couple different methods used.  My takeaway on this is not so much that one is better than the other, they are just different ways to do the same thing.

You might see an "LFO frequency" in a reverb control panel, but this is not full control.  The reason I suggest this approach is that SpinCAD Designer is not really set up to build reverbs.  A few full blocks are included as a convenience.  If you want to deep dive on modulated reverbs I'd suggest asking over at the Spin forum.

I have given some thought to making blocks etc. that would in fact lend themselves to reverb design, but it's a lot of work for (in my opinion) fairly low ROI as, in order to really understand what you are doing, you might as well work in the Spin ASM anyway.  Also, I think people think they are going to come up with a "better" reverb than the ones offered as samples by Spin themselves.  All I can say is... "good luck"!  I have, however, been able to extend reverb times into the 90 second range (by hand editing Spin ASM), which is really strange.

Since you asked, I've set up a Patreon site to go deep into what SpinCAD Designer is, how the program itself works, and how best to use it.  Some of the articles are available to the public, but of course many of the more interesting ones are not.   I do actually occasionally talk about what I know about Spin ASM and all of that independent of how they are handled in SpinCAD Designer.  My goal is to share what I know with people who are interested in that sort of thing.

Thanks for the info Larry! I have been reading up on stuff for a while, so it looks like I'm going to have to learn ASM. I've picked up stuff along the way by looking at code examples. I was considering the FX Core setup, but their isn't as much support out there yet. Thanks again

The other point is that the "chorus" blocks in SpinCAD should probably be marked "vibrato" as it's only the modulated signal coming out.  The "exercise left for the reader" is to mix it with the dry signal whatever way you want, with/without mix level control or phase inversion or whatever.  Learn more than you ever wanted to know here:  https://www.patreon.com/posts/making-and-fine-68653734
