Setting the sample rate to 8*48kHz increases the meter percentage by about 8x on all modules compared to 48kHz for me. (e.g. Audible Instruments Modal Synthesizer goes from 1.8% to 10.5%.) What modules are you testing that don’t seem to change their CPU percentage with different sample rates?
VCV Rack Studio Edition comes with Core and Fundamental just like Rack Community Edition. All other VCV modules are à la carte.
I’ll check again. Perhaps I was just mistaken. tx.
OK, I found it. If you have no audio module installed, start up rack and turn on the CPU meters, they are quite low. If you then set to 8X it doesn’t change. But if you quit and then reload the session they jump to the right values.
It’s that if no audio device is in the patch sample rate changes make no difference to the cpu meters.
In VCV 1.0 it worked “as expected”.
So, the multiple audio interface thing in the VST has been discussed a few times, but how does the VST handle multiple MIDI interfaces?
If I have 1 instance of the VCV vst, with several voices (drums, synths) can I let several Ableton tracks send midi data to each of these voices in the single instance? how does the VST handle this?

Hi everyone … I can’t choose my Focusrite sound card in VCV v2 … it doesn’t even work with a similar audio configuration as in VCV v1 … I’m on Windows 10 … is it because some things are still changing until November? Thanx
You might want to give your topic a better title, such as: “Focusrite audio interface not working in Rack V2”, and maybe give some details as to what model of Focusrite interface you’re talking about
thank you for the reply … my message was also a reply, so I couldn’t give a title, or do you mean that I should create a new topic?
it is a model: USB sound card Focustrite Scarlet 2i2 In VCV v1 or in DAW it works properly via DirectSound, only in VCV v2 it does not … VCV v2 sees my card, but when I select it via the DirectSound driver as in VCV v1, the program crashes.
Sorry, too little cofee, the wording and the way my browser showed it looked like it was a completely new topic, which of course it wasn’t 
… I am mainly interested in whether VCV v2 is still in the development phase, and when it is done (allegedly in November) then whether everything will work as in VCV v1. Because I’ll wait calmly until November, I just don’t know if I’m not pointing out too early to some problems (which I described above).
If something works in V1 and the exact same thing doesn’t work in V2 it could be a problem, so I think it’s great you’re pointing it out.

ok … thanx … so I guess I wrote in the right place

Probably best to create a new topic so it’s gets seen by the powers that be. Call it something like “My Focusrite interface is not recognised in V2 (but is in V1)”

Mine works
- Windows 11
- Focusrite 2i2 Gen 1
- driver Focusrite_Usb_4.65.5.658
- VCVRack 2.git.042a9ce0
I noticed that focusrite ASIO defaults to block size 192 on a fresh install. Rack2 changes the block size to 256.
Hi and thanx for reply … ok … I tried and this works for me, but I’ll probably have to rewrite all my previous patches in notepad if I want to open them in the future. It was better if the DirectSound driver worked, if it can already be selected in VCV.
I can select directsound - but it doesn’t sound right - crackling - like a sample rate mismatch.
In windows 11 sound settings, I can only select 16 bit 48000Hz or 24 bit 48000Hz for the Focusrite. I didn’t see that before. Everything else sound ok - perhaps using WASAPI.
In Rack2 - Focusrite sound is OK using WASAPI and ASIO - but Directsound is crackling.
BTW, the new .vcv format is binary - I don’t know of any text editor for it. Perhaps some incanation of unzstd and tar can open it. I don’t like binary patch files.
tar --use-compress-program=unzstd -xvf patchfilename.vcv
extracts "patch.json", which must then be tar'ed and zstd compressed to .vcv to load in Rack2
hmmmmm …
WASAPI - sees my card, but when I select it, the program crashes … only the internal REALTEK can be selected.
ASIO - Asio4All only works. When I choose the Focusrite USB 2.0 Audio Driver (1-2 in, 1-2 out) directly, the text pops up: Device sample rate could not be changed becouse the following applications are playing audio. But no sound or music or web have played.
DIRECTSOUND - sees my card but I can’t select it at all. here also, only the internal REALTEK can be selected.
please discuss the driver issues here:
