A place to talk about whatever Scope music/gear related stuff you want.

I mostly interested in tinkering with something that can do this in modular or in the sdk.

If I get stuff up and running I’ll investigate further.
You won't be able to achieve a full 1second of variance in Modular, as far as I am aware. Meaning, I don't know how to create an addressable range of delay that is variable in time across that many samples, it's certainly possible to have a delay line that's more fixed up to that length with a small amount of variance in terms of samples or milliseconds. But I would simply use pitch tools to emulate this or look elsewhere.

Where else? Well you might try finding some of Strymon's offerings and putting them through an external effects loop: https://www.strymon.net/product-categor ... ts-pedals/

Yeah that was my understanding all along. That it can’t be done, or at least was hard to do, since being able to do something like this is a relatively new addition in scope. But will have to check modular IV tape delay and BBD as people have mentioned in this thread. And see what the max delay time is.


Thanks.

It can't be done with what is currently exposed in the SDK and Scope itself, that isn't the same as saying it isn't possible to create something in tandem with S|C using the tools that they have from Analog Devices. In the Xite era, I don't actually know all of the architecture of the newer chips that are used, so it could be the case that it could be more directly implemented. I do have an Xite with an SDK key here, and haven't used it to the depth that would be necessary to properly answer that question in that context.

In the PCI era, too much use of the host system (which is what you would need to do to address that amount of a sample-addressed buffer array) was a stress on the host PC. This is what was established before, and why attempts to even keep the STS samplers working fell by the wayside. There was just too much of an advantage for native software implementations, and so most of us focused on using Scope where it's strengths were (realtime processing of signals passing through it, and low latency reliable synthesis with sound quality and resources that didn't vary once allocated--unlike host PC's from that time).

I've previously had the Roland RE 201 and still have a Phonic PDD 3000 which can also create the effect you highlight in the original link

There's a research pdf on emulating the Roland RE 201 digitally
And in the manual for the Phonic PDD 3000 there's a block diagram and circuit diagram, send a pm if you're interested.

Wondered if these may help in recreating this effect in Scope SDK

In addition, I know this isn't Scope but there's this from Roland

Thanks. I already have a tape echo and a bbd and a digital echo. I just love echos. And if possible, would love to great one in the sdk, if I ever get that far.

But first I have to get my card up and running and I will take things from there. But thanks Rafe.
