Several companies have asked this question over the years and the usual
result is a product that ends up costing significantly more than £2500.

However it is certainly possible to roll your own custom keyboard synth.

Ken Restivo has done it and had some success.

Boot time may be an issue if you want to load a full desktop environment.
However it is also possible to boot directly into X and run your UI there.
That also saves a few resources but means you are locked into a specific
application.

If you don't need a visual environment then you can run without X. I have
servers online running this way. They don't even have sound cards and use
jack -dummy instead. Everything can be controlled by external hardware
and/or command line fu.

If you want to save yourself time and hassle buy a prebuilt manufactured
solution. If you want to save some upfront costs but are prepared to spend
your time and efforts then you can build your own and make it work. You
might not get much appreciation from the audience as they tend to get
gooey over sponsorship agreements rather than self realised technical
expertise but you will solidify your tech cred with the gear head crowd
who do appreciate such things. i.e sound engineers, lighting technicians
and roadies.

Probably a good scene if you are into hairy, dirty, sweaty, boozy men ;-P
