I wish your could support me on this. I bought this Primus A25 keyboard from ebay and I was so disappointed that the box I got from the seller does not contain the software installation CD. I contacted the seller who said he also bought this unit second hand similarly without the installation CD.

Does anybody know where I could purchase the installation CD or does your support include providing free software installation CD? I have tried using the driver downloaded from your website but it doesn't work (installation stops somewhere) and my Macbook doesn't recognise the device although it powers up with the usb connection. 

I'm using Mac OSX v10.11.6 and Logic Pro X 10.0.7.

I hope I receive good news from here and from anybody.

Thanks
