Jesusonic 1

Jesusonic Software turns your PC or Mac into a fully programmable realtime effects processor. If you are going to run on a Windows PC, we recommend you just install REAPER, since it includes the most recent version of Jesusonic, and offers a LOT of routing flexibility with very little downside.

General things to note before installing/running:
Remember that this is just a preview release--many things may be broken, and it may not work completely as you expect.
Be sure to turn your speakers down! If you run Jesusonic and it is sampling the input and outputting the output, you could get some nasty feedback if not prepared.
On Windows, set up your mixer settings accordingly. Once you run Jesusonic, it will let you choose the input/output method. For low latency, ASIO or Kernel Streaming is really a must. Kernel Streaming should work most of the time, though currently it just uses the default sound devices, so you may have to change this in the Windows control panel. If you have an ASIO driver for your soundcard, this is the vastly preferred way to go. A good ASIO driver for USB sound devices is available (though not free) from usb-audio.com. A good ASIO driver for all soundcards (it just wraps the WDM driver) is available at asio4all.com (and is free).
