Thank you for the quick reply Brad. One more question I forgot to ask on basically the same topic, how do a get Banks A-D to stop sending midi information out? Sometimes they are triggering midi instruments that I don’t want them to?
change their midi settings.
this is all in the use manual.
track settings, scroll down to MIDI. change the settings.

New here. Awaiting my S2400 to be delivered. Can someone explain to my why I need this DSP? I already have all these effects by running my SP404MkII through the S2400.
I kind of enjoy not having my Sampler full of bugs because of outside VST’s
Where do you see any documentation stating you “need” the dsp? no one “needs” it - its an option the devs made for those who want their efx in box. seems you have your bases covered with external gear, so the dsp ain’t for you mate…
I usually see people just running the main output of their sampler through the 404s effects, which is what the DSPs LiveFX on the 2400 is similar to. So this option seems covered for you.
With the DSP card though, you can also add several effects on individual tracks.
Personally I use it to e.g. eq and compress the kick differently from the snare or put reverb on one sample and something else on another. Also there are return busses for group processing og sending to wet effects and so on.
I don’t own the SP404MkII, so I am not sure if the last of the above is possible when combining the machines. Otherwise, this could be the benefits.

Thanks Dave. As a new customer and new member to this forum I was curious as to WHY I might want or “need” this upgrade and you’ve explained it clearly.
Once I’ve had a chance to play around with my S2400 I’ll decide if I “need” the DSP. It does sound enticing I must say….it will make my 404MkII kind of obsolete!
I’d also add that being able to connect a midi keyboard and play around with different virtual instruments all within the s2400 makes the DSP card pretty dope.

Has anyone successfully deployed a vst3 plugin? I have two (comb filter and fdn reverb) that work fine when tested on x86 but when I push the cross compiled aarch64 packages, sync and reboot I don’t see them at all on the s2400.
Just finished installing my DSP card and everything is working! Just a warning for those doing the install; I bent quite a few pins removing the ribbon cable between the two internal circuit boards but successfully bent them back with needle nose pliers to mount the DSP card and reattach the ribbon. I was sh#$ing my pants though…

Quick update on the vst3 front. I built an aarch64 development vm running arch linux to “natively” try building a simple comb filter vst3 effect so that I could run the vst3 validator on it from the steinberg vst3 sdk (can’t do this when cross compiling on x86). The validator ran perfectly and the plugin passed all 47 tests. Nothing obviously wrong with it. I transferred the vst3 directory with the .so to the S2400, sync’d and rebooted and still no dice. Not sure what to do at this point except switch to lv2… which is lame because rdf/turtle is just awful to deal with. Anyone have any ideas?

I just built an lv2 version of the comb filter and it works awesome on the S2400 so there’s likely an issue with the vst3 host. All good, I’ll just stick with lv2. Sorry for all of the noise.

Definitely signal, not noise.

So far I’ve successfully developed the following lv2 effects plugins:
- variable filtered delay
- feedback delay network reverb - with NEON optimized Hadamard matrix
- implementation of freeverb
- korg35 lowpass and highness filters (ms20 filters)
- suite of wave shapers (chebyshev, atan, wave folder etc)
and lv2 instruments:
- jp8000 polyBLEP 7 oscillator, detunable super saw mono synth with amp and filter adsr and ms20 filter
- saw/square/triangle polyBLEP based 2 oscillator mono synth with amp and filter adsr and ms20 filter
- saw/square/triangle polyBLEP based 8 voice, 2 oscillator per voice polysynth with amp and filter adsr per voice (so vca and ms20 vcf per voice).
Everything sounds absolutely incredible. After NEON optimizing the FDN based reverb I haven’t really hit any realtime limits (no dropouts or anything) but I haven’t stress tested much. I’m so incredibly impressed with the S2400 and the DSP board… This thing is literally the best piece of gear I’ve ever owned in like… 33 years of making weird music 
I’m currently working on a high resolution wavetable based band limited oscillator version of the mono and poly synth but I keep getting the dreaded “Insert error” message and I feel like I’m wearing out my power switch. It’s plaguing my development effort to the point where I think I need a copy of the sysroot from the linux distro on the DSP board to cross compile against. It would also be awesome to know what lv2 host is running (jalv or something?) and my dream would be to be able to ssh in to the board and generate/view logs or something. Anyhow… any info would be super appreciated.

This sounds awesome! Do you plan on releasing this stuff? I’ll go on record as an interested customer!

oh yeah totally but you can just have it for free as I’d rather it just be open source. I’ve created a ticket asking for a copy of the sysroot so I don’t have to play guessing games and convert everything from C++20 to C99 when I hit a snag. I have a convolution reverb that I’d like to try to port over as well.
