This is a beautiful box of knobs and sliders. Hand built per order by Synthark and made specifically for the Ensoniq SD1 and VFX synths. This was just made for me and I paid about $700 for it but I have a lot more gear and just don't use this synth as much as a lot of my other stuff. I only used this for maybe 20 minutes total. NO SYNTH comes with this purchase. You get the freshly built programmer and a plug to power it. I can provide all the info that I got from Synthark about this programmer. These are not even listed on their website!!! Made specifically for my studio but.... yeah. One thing to note is Ensoniq synths need to be retriggered to hear changes made. I barely touched it and am not a big midi cc guy BUT if you have any questions, Synthark is pretty quick to reply and can answer you questions better than me.
