VCV Rack is the most exciting thing to happen in the open-source audio world in years. The community support has been incredible: just do a search on Github for VCV Rack and you’ll find a wide variety of modules that have sprung up in just the past few months since VCV Rack's public debut. If you're new to VCV Rack, I would definitely start with the included modules, but when you’re ready to branch out, take a look through the directory at http://www.switchedonrack.com http://www.switchedonrack.com.

I managed to crash it on macOS by having a second audio interface. After that, there was no output signal anymore (even after I deleted the second). I was about to give up, but impressed that the project I made was saved pretty much till the state before I added the second interface. Do you know if its possible to get instruments like TB-303 and TB-808? Does anyone know a multi-platform MIDI keyboard to accompany this synth?

  Multiple audio interface support is experimental. This is a feature even AAA DAWs do not have, and if so, they are "amalgamated interfaces" rather than separate simultaneous connections. If you get into a crash-on-boot loop, remove the "autosave.vcv" file (or edit out the Audio Interface modules from the JSON with a text editor) and relaunch Rack. For TR-style drum machines, third-party company Hora has released a set of modules at https://www.facebook.com/Hora-Music-1826383014249093/ https://www.facebook.com/Hora-Music-1826383014249093/ and https://gumroad.com/horamusic https://gumroad.com/horamusic.

    ASIO4ALL has had multiple audio interface support for a long time.

      That would fall under the aformentioned "amalgamated" interfaces. In Rack you can (theoretically) plug or unplug new interfaces with a different sample rates and block sizes without rebuilding your virtual interface, since they are treated as individual streams (one per Audio Interface module) instead of being multiplexed and synchronized. But I haven't reviewed the source for thread-correctness and tested carefully enough to deem multiple interfaces stable, so in practice, you might get jitter, crackling, crashes, etc. if you use this feature. Some interfaces work flawlessly though.

  You could probably create a pretty 303-style voice pretty easily. One osc, a filter, a vca and an envelope should get you 80% of the way. For keyboards are you meaning a soft keyboard or hardware? There are a ton of high quality hardware keyboards under $100 available and they'll all use class-compliant usb midi so work painlessly across platforms.
