DESCRIPTION

v1.2 Changes:

- Fixed two wireless connections that were going out to the wrong stereo outputs
- Reset the global output of the ensemble to 0dB. No idea why it was turned down
______________________________

v1.1 Changes:

- Added unit delays to the feedback path within the tank and also within the feed-forward path of the allpass filters to maintain full resolution
- Added basic input information to the Core cell inputs for quick & easy parameter setup
- Fixed a hilarious typo on the front panel I didn't notice
- Simplified labeling of Core macros for a more elegant structure
______________________________

Standard Issue Plate is a modern reiteration of the classic “Dattorro Plate” reverb algorithm discussed in Jon Dattorro’s 1997 paper “Effect Design Part 1: Reverberator and Other Filters”.

I’ve added a few things like dual input diffusers acting on a stereo input (rather than the mono-summed input with a single input diffuser) and some additional modulation routed to the rear allpass filters in the tank.


Other than that, this is a tried-and-true plate algorithm that has been used in countless applications for almost 30 years. I just wanted to get my arms around it since I feel it’s kind of a “right of passage” algorithm within the reverb design community.

The delay times have been scaled from 29,761 hz to the more modern 48,000 hz sampling rate. You can still use a lower sampling rate, but the delay times will be somewhat longer. Aside from a few basic primary UI elements, everything is done in Core and is feather-light on CPU.

The structure inside the Core cell is straightforward enough to be cross-referenced with the original paper, keeping in mind the scaled delay times, so it can be useful as an educational resource for anyone studying this algorithm.

This is so wonderful. Thank you very much for sharing. :D

Bryan, this sounds amazing, well done. I thought this may be improved by setting all the delay times to a prime number of samples but this turned out not to be the case and I don't know why. Again, really good and super light CPU wise.

Okay, v1.1 is up and she sounds much better now at full resolution. This was my first Core ensemble and, though I've used unit delays within feedback structures in other programming environments, I forgot to include them in the first version. But that's all fixed now. Enjoy!

Thanks for letting me know, Studiowaves. This was my first Core ensemble and I completely forgot about unit delays. I'm working on an update. The overall resolution has improved significantly. Standby.

Sounds good. A (z^-1 fbk) then FBR at the end there to resolve feedback with take the red lines out. Nice sound all in all. Plates have always been my favorite.

it is not unchanging here... the river flows inexorably; unyielding stone is shaped/ the deeper beauty is revealed...

Thanks a lot man! It's gorgious. Very nice sound and indeed lightweight. Putting it to use in maschine. The GUI is also really nice. Love the look :D
