I spent the last month making my own home-made USB control surface: a Velleman USB IO board, a multiplexor board of my own, some home-made pressure pads/ribbon controllers, and various pots, switches and plugs for external pedals and controllers. Looks good in a brown leatherette upholstered box. I'm working on programing the USB to MIDI software so that it can be an input for VSTs. Lots of fun.
Then, I return to the office this week only to discover that while I have been away, our friend Gilles from Cordanova had popped over from France to Sydney to deliver a Cordanova VMX Studio MIDI/USB control surface. Gilles used to work at my office when he started designing the VMX, so it was interesting to see which of the ideas that people had floated about had made it into the final design: I had suggested that it should have at least one big knob and a slider so that it could function as a DJ control surface as well as for synths and mixing, and also have a variety of switches and knobs, and I am happy these made it through.
But it is embarrassing to see how much better build quality the commercial product has over my home-made one.

I used a Velleman kit 8055 which uses USB. The schematic comes with the kit, and is probably in the PDF manual online from them. The software on the PC is a simple polling loop, which converts the results to MIDI. Not really efficient.

Have You got a schematic of MIDI/USB interface? Or where I find it, please? Regards
