It's linux only, and MIDI only, and it needs GTK2, but yeah, it should work on modern linux. You can use jack[1] to connect the midi output to a softsynth, or another drum software (e.g. Hydrogen[2]) or to actual MIDI hardware. There's a video demo[3] of my program I made 3 years ago. The pasting of drum tab is demoed at 6:20 in the video. [1] https://jackaudio.org/. - Source: Hacker News / 9 months ago

Im pretty sure that asio4all drivers dont run on linux, I think its a windows exclusive driver. But I think that JACK is something similar, Im not sure though, since all I have ever used is windows so I havent had a reason to look into it. Source: 12 months ago

If you're looking for a realtime VST Host, I use Carla with the JACK Audio Connection Kit for low-latency EQ and other FX which are realtime on my Microphone, which then get redirected to a virtual microphone (all on Linux, should still be possible on Windows). So far that worked greatly. Source: about 1 year ago

Jack is supported on main platforms . Make sure to read the wiki . Also, some Realtek drivers has the Stereo-mix option that allows you achieve what you want. If yo have the default audio driver that Windows install it may be missing. Source: about 1 year ago

Wonder if a virtual audio cable would help. https://jackaudio.org. Source: about 1 year ago

Also, for software/hardware check out Native Instrument's Traktor Pro 3 and SeratoDJ. Source: over 2 years ago
