Dave Smith Instruments SYNTHESIZERS

Hi group,
having returned to 'music making' after a few years adrift have only 
just got around to ordering my V3 PIC chip for the desktop Evo.

As I no longer use computers for music (hardware all the way baby!!)
what is the easiest way to load the syx file to update the DSP ?

Have a copy of Sonar LE that came with a keyboard controller, presume 
this will handle the operation - if so could anyone be so kind as to 
indulge my s/w illitirassy and give me a few pointers as to how to 
proceed. 

many thanks,

Graeme
