Porting Madrona Labs' Reverb to 301?

recently madrona labs released a very lovely reverb plugin called altoverb.

i think it sounds great – and apparently it’s pretty lightweight…

the developer, randy jones, was kind enough to make the code available for anyone who would like to port it to other platforms:

I’ve just updated the madronalib source with a couple of new sound examples based on RtAudio. One of these is an Aaltoverb example. If anyone’s interested in porting it to norns (or anywhere), feel free to ask me any questions you have.

The basic algorithm of this is something that I’ve been playing with for a long time, since I made the yafr~ example for Max/MSP (in 2001 or so?) based on the Dattorro paper that gave away the idea behind one reverb “in the style of Greisinger.” (Lexicon)

My newer take on it is that all the allpass delay lines are smoothly modulatable using an idea proposed in “A Lossless, Click-free, Pitchbend-able Delay Line Loop Interpolation Scheme” (Van Duyne, Jaffe, Scandalis, Stilson, ICMC 1997.) So the size can vary from small to large without clicks, which I won’t claim is unique but I don’t hear most reverbs doing.

i’m wondering if a version of this could make it’s way into the 301? i know the C++ layer is currently only accessible to @odevices - so i guess this is a bit of a direct request :wink:

I love this idea!

(Just adding to the chorus of enthusiastic supporters.)

+1, I’ve just listened to the demo. Would be cool to have this in the 301

this, if possible. would just be an extra layer of awesome…tom erbe has a few freebies and any new designer would be very wise to offer a few to er301 users to try their algorithms before buying their “x” product, its just how accessible it is to us on the 301

+100.

Brian: would this be possible ?

It would really make sense as er301 is a “sound computer” ! :slight_smile:

So should i take the lack of response as being an answer no ? :wink:

EDIT: i mean regarding open source code for fx…

Im sure there’s lots of potential for these type devices such as the er301, but often wonder if they are only mostly meant for people that have the time to learn to program them.

Sorry. I have no concrete answer on this at the moment.

I obviously don’t know the big strategy/paradigm of ER301 - is it closed system for 3rd party components, allowing them with some trust, or even future marketplace :slight_smile: but some quality and music reverbs will help. From the other side, I don’t know how much cpu power is needed for quality reverbs. If so much, I will stay with mine OTO BAM and Axe-Fx outside of modular case (I can’t see any quality reverbs in eurorack now).

Glad to see this bumped…and yeah, good points. I just hope that good stuff will be shared for the people who arent lucky enough to have had the time/money/ education to learn code.

Seems like porting(is this the right term?) open source code to er301 seems like it would be good for everyone.
Am i right ?
