Hey, quick question. Why is it not possible to route the DSP mixer to USB? Given that it’s all internal digital signal, it should work.
I don’t mind it for reapplying reverb but for other fx and sound sculpting it’s really annoying to have to recreate it in the daw recording.
Main mix out to usb is possible, right?
I you meant the individual outs I agree. Few months back this was already mentioned but hasn’t seen any attention since.
Thanks. Yeah main mix is possible, which means recording the channels one by one with mutes. Doable but not ideal (since there’s also multiple patterns to consider).
I think this should be an fx board level feature: route the individual mixer tracks to usb channels. Fx board could likely handle this on its own.
We’d need a toggle (usb out channels vs usb out mixer channels, and the latter option would not exist if there was no fx board installed).
Any input on the viability of this?
@bradholland ? @isla?
@bradholland I am also wondering if individual outs over USB to DAW is on the roadmap? It would be a great timesaver. No sweat either way. Love using my S2400, this would be a Brucey Bonus 
It’s there, just not from the DSP mixer which means that any effects applied cannot be routed to daw over usb…
Hi Jean,
Thanks. I forgot there was a separate DSP manual! I just read in it (page 6) that
“DSP Main to USB Check to send the DSP Main signal to USB audio main out. If unchecked, the USB audio main out will be dry (pre-dsp). The eight individual USB audio outputs are always dry.”
Cheers.
Yes, what I am hoping for is that eventually, we’ll be able to route the individual DSP mixer channels to usb audio as well.
Maybe someone from ISLA, maybe @bradholland , can explain the reasoning behind the omission…
I’m delegating this one to @av500
There is a reason why it hasn’t (or maybe can’t) be done. but the reason eludes me right now.
Cheers Brad
Cheers Brad!
there is only one free stereo channel to route audio back from the DSP to the main CPU and that is taken already by the DSP main mix
OK, noted, thanks!
So that means that it’s definitely never going to work?
Why did you design it like that?
That’s a bit of a disappointment to be honest. Either going to go all-in the box, record channels separately and/or buy an external mixer with usb multi-channel out.. 
I agree, makes the DSP less of a must have…
Totally didn’t expect this tbh. This kills a considerable chunk of my FOMO.
Yeah don’t worry about it, I have it and never use it. For me it’s much more convenient to just wire everything into my daw over usb and use lean vst fx. For sound design and resampling I just bounce back and forth between a 404 anyway.
Currently the DSP board is just a collector’s item with little added value and a firmware that is more buggy than the one before the DSP release.
The DSP board is great, how it works has never been a secret. Think of the DSP board as an analog mixer with channel inserts and two sends, built into the S2400 audio path, and under control of the S2400.
Check out this post, there’s a lot of useful info in the thread in general. It explains the DSP hardware architecture.
If you remember way back when, the initial discussion of FX were that they were going to run on the S2400’s own CPU. If that had been the case, those FX would have been in the digital domain.
Instead the DSP card sits in between the main board and outputs. The built in analog filters aren’t part of the DSP audio, either.
lilbrimstone explained a useful workaround,
“with the current firmware it’s possible to record DSP in a live loop if the live loop input is set to USB. No cables required! I can do pretty much exactly what I’d like to do, it’s just cumbersome like I said. The sequencer has to be running and you only get the length of the pattern to record, then you have to convert to wav and delete / add to track.”
You can also do it if you have a mixer via the live looper.
There are all kinds of options for what you are monitoring and how.
Later in the thread av500 said that resampling with dsp via a menu is in the roadmap
Yeah I know how it works.
It’s not an analogue but a digital mixer, but a digital mixer that can’t output its digital signal to the digital output interface of the main unit.
Wiring the S2400 to Ableton Live over usb is also making use of a digital mixer. And it’s more convenient for me as I actually get the fx just the way I have set them up in Live and can record right away.
I think the DSP board is useful for people who have an actual analogue mixer going direct to recording, but no fx in their analogue signal path, or for people who have something like the Model 12 wired to their daw and record their model 12 in the daw but don’t wanna use their daws fx…
The beauty of usbc recording is that you can cut out the middle man, apply fx directly on tracks in the daw, record everything right away, bounce, be done…
With the DSP you don’t get any of those fx on the usbc channel outs. So why even bother applying them in the first place?
I read about the resample perhaps coming up at some point in the future. Good idea for people who do not have a 404 next to their SP, setting everything up in the DSP takes about as long as simply going roundtrip through the 404.
I stand by my point that it’s more of a collector’s item than an actually useful addition for anyone who also has a computer. The 2400 isn’t really portable so there’s really no use setting up fx for shows either.
Who is it for besides people who rely on vintage tech (analogue boards) without themselves being vintage (no outboard fx)?
