Note: I'm working towards patenting this idea so I apologise for the general nature of the details below.
Once the patent is secured more useful, 'build your own' information will be posted.

Basically I wanted something that I could link all of my sound hardware through, deal with signal
incompatibilities with and if possible 'play' and modify the sound in the process before piping it out to another effects box or a mixing desk.

It's amazing what you can make from junk and cheap micro processors and an old print server casing.

Like most effects units the Knob Box relies heavily on the incoming sound input to generate its output.
At its core are two oscillators and an array of fairly standard effects.

What makes this unit different is that it runs the sound from them through one to four channels depending on your needs.

When all BNC ports are terminated only the RCA in channel is in use and it's a basic effects box. But when you remove a terminator that channel becomes active and the effects selector acts on that new channel combining the previous channel's input with your new selections.

You can then layer or loop new or the same effect over or on top of the previous effect and control the amount of effect acting on that sound using the Effect Saturation control.

The really neat part is that unlike traditional effects boxes where you are stuck with running the same effect around inside the box, you can then patch new incoming sounds onto the three BNC connector channels on top of the existing mix to make some truly great, and sometimes horrible sounds.

Check out the demo movie, it might make more sense.

At the moment it's only mono sound in and out but I'm working to improve on that. It will take generic expression pedal input but it doesn't work quite right and seems to get 'stuck' so that needs to be fixed.

Due to the free 'add sounds as you go' architecture it's going to be an enjoyable process of finding out what exactly this little box can do!
