What would you like to see from ValhallaDSP in the future?
zDSP cartridges!

Thinking about it.

I need to get ValhallaÜberMod out the door first. The plugins are my bread and butter. Honestly, though, the Z-DSP cartridges might be pretty quick to develop. I'm already pretty fluent with FV-1 assembly, and the Z-DSP stuff doesn't require a GUI & all the other stuff that makes plugin development kinda slow.

I understand. Just having some fun on a slow day. I should be busy programing DREAM chips but again I'm waiting on someone else' deliverables.

Um...DREAM chips? What are those? Something useful? It sounds familiar, but I am having problems with my recall today.

Wow. Can you say more about your work with these? They look interesting...

I can't say much. M-Audio's Venom and their USB 2.0 audio interfaces use DREAM DSPs. I work primarily with the SAM2553 (for what/whom I can't say), which can act as a sample playback device, simple FM synth, signal processor, etc. with built in MIDI and audio CODEC. They are very easy to work with (in terms of programming your own algorithms and functions) and the higher end chips are extremely capable. I can't really compare it to anything else cause it's really the only platform I know. I'm still a noob with all this embedded stuff.

My view is that since you know so much about reverb algorithms, they seem to be what you care most about and since youre so good at developing them I'd suggest continuing in the same vein - it isn't easy to be world class in several disciplines if you're a small company.

Personally, some of the best reverbs I've used was from some true stereo impulses I made myself using a tool from Voxengo called impulse modeller, which produces impulses by raytracing. You get very silent and smooth reverb tails. (It isn't really meant to produce true stereo but you can position the emittor left and right.) Now, the problem of course is that these impulses will have the same problems as impulses always do, i.e. they gobble up CPU and/or produce latency and are basically set in stone, you can't edit them. The whole exercise also seems a bit idiotic, since the impulse is a product of an algorithm in the first place.

Now, my question is: would it be possible to use some similar kind of raytracing scheme in real time? Has anyone tried it? I'm aware of a software called Rayverb, but that appears to require an actual impulse anyway. To me, the classic early/late reflections principle seems to lack basis in reality (although it can obviously produce great sounding results).

I personally would love to see/hear a something with granular synhesis featuring host syncable LFOs/ADSRs (maybe even with user definable waveforms). That might either fall into the "Pitch Shifting things" or "Weird noisy texture things" category!
I just discovered the beautiful world of grains and would love to see an according processor done by Valhalla DSP

!

My second choice would be a dynamic processor.

Looking forward to it in any event

!

Take care!

I would really enjoy a dynamic processor in the transient sharper vein. There are a few options out there, but not a ton and the less expensive and free ones are not perfect.

Or a really musical, varied distortion box. Distortion/overdrive rules the guitar world, but the digital choices are limited, unless you want to run things through a big clunky amp simulator.

I wonder if you would be interested in trying mimic a lofi/circuit-bent reverb/delay. I have a few Boss Micro-Rack units; RRV-10, RPS-10, etc. and on each of these, you can replace a resistor in the circuit which generates the sampling clock to get much longer delay/decay times. As you get up to like 1 minute of delay time, the sample clock is so slow that the resolution becomes audibly degraded. It sounds amazing though. There are other mods you can do to these boxes that produce some dramatic effects (increasing feedback to get screaming self oscillation, routing audio to the switch inputs. I love these kinds of mods that leave a device functionally intact but allow you to manipulate sounds in ways that weren't intended.

I was hoping that Uber-Mod might be able to accomplish this kind of sound...

or the break down in the middle of this peice...

If not, would you consider building an effect that could do these kinds of effects?

ÜberMod will be able to get some cool sounds, and has a half-speed button for lower-fi delays. Lots of noise and distortion on tap. No aliasing, though.

Do you have any links for the Micro Rack mods? This could be something to explore for future plugins.

Amazing tracks as usual, Justin!

Regarding future Valhalla products: I'm still voting for a distortion plugin with a Valhalla twist. ValhallaTrash

It will need a bright and dark mode again though. That should become some kind of ValhallaDSP trademark.

Cheers

"Trashalla" !!! You can totally use that name Sean.

justin3am · Post by **justin3am** » Tue Dec 13, 2011 9:14 pm

Yeah, it's mostly the aliasing and the corruption that occurs when noise starts getting introduced to the sample clock, that I'm looking for. Thanks for the quick response!

I read about modifying the delay time of the RPS-10 here...
http://www.experimentalistsanonymous.com/ it's posted somewhere on their forum.
I found that the mods to the RPS-10 could be applied to the RSD-10, since they are pretty similar. Then with some exploration, I discovered how to do similar mods to the other units. I didn't take any note during the process, though. These boxes are all pretty primitive/simple so it's not difficult to learn what parts of the circuit do what.

I'll have to think about how to simulate that on the cheap for future plugins. The noise would change the delay time, as well as the aliasing frequency. Implementing accurate resampling would be way too CPU intensive, and wasted on an application where you want MORE aliasing noise.

I found the link:

And I have an RPS-10 in the basement. Food for thought...
