Re: [Csnd] [EXT] CSOUND Digest - 10 Feb 2026 to 11 Feb 2026 (#2026-31)

Hey Jeanette:

While the code may not be that elegant, you might try my MVerb or MVerb3D. These are physical models using waveguide meshes (MVerb is a 5x5 mesh while MVerb 3D is a 4x4x3 mesh). Rather than providing room dimensions one tunes the waveguides by providing resonant frequencies as well as control other aspects (reflection coefficients, filtering, and an overall size coefficient applied to all of the delays). I have found that I can get a great variety of room sounds as well as some interesting experimental “reverbs.” It also may not be the most efficient effect, but I do like the sonic results. You are, of course, welcome to have at it–this is coded in Cabbage. You can find it here:

along with a few other things I have been playing with here:

I would be curious to hear if this is of any use for you,

Hi Jon and Thorin,
@Thorin Hm, it might work with the stereo mic mode.

@Jon Thanks for sharing these. I do remember that I have come across them before. I don't think that MVerb might fit my current use-case, but the reverb looks interesting enough. From what I've seen, I'll have to do a bit of recoding though, due to a different scenario, i.e. no Cabbage. Still: never look a gift reverb in the early reflections! :slight_smile:

Best wishes and thanks,

Jeanette

Aman will work on a binary version for this, I think it should be added to Csound with due credit to Jon of course.

Hi Thorin!
thorin kerr, Feb 13 2026:

There's an 'uncabbaged' version of Jon's mverb in here if it helps:
cslc-csd/Sounds.orc at main · ErrorThink/cslc-csd · GitHub

Thanks for reminding me of your great collection as well. I already had
it and forgotten about it. So much material. But yes, this might be of
help.

Best wishes,

Jeanette

Hello Csounders,

It would be great to have jon’s mverb opcode in csound. If this is the plan. Hope so.

Thorin,

I would love to see some performance videos of you live-coding with all this amazing stuff.
I would love to see some tutorial videos of you stepping us through how you use it.
Maybe there are some links, and I missed them.
This all seems like such a wonderful collection for music-making.

I have been a fan of your work and shared it with my students for years.

FANTASTIC! I (and we) can’t wait. They (and I) are always blown away by your super cool stuff!
