I recently purchased it with the plan of using Neyrinck's software and it does work fine, but I am starting to think its just too big for my space so will consider fair offers. Pics on request, but I can tell you its the cleanest of clean(been in temp-controlled storage for over 10 years). It received a new PSU when it came out of storage(in prep for sale). All the sticky stuff has been meticulously removed. I can deliver in New England and eastern NY(for a fair fee), or buyer can send a truck(I can also build a plywood shipping container with foam padding for safe travel on a pallet).
The full history is that it was purchased(new) for the Creative Arts department at Foxwoods Casino(in CT) and was used in a studio setting for around 3 years when the department was closed. At that point, all the gear went into temp-controlled storage. Around 1 year ago, the audio department received permission to sell the hardware(there was no need for it in the audio department). The Control 24 was tested and found to have a PSU issue, so a replacement was purchased(new) and installed. Then a package of gear was listed with one of the Casino's preferred audio vendors and I purchased thru that vendor 2 weeks ago.
Looking at eBay and Reverb.com, current prices for functional Control 24's range from around $1k, up to over $2K and none are this nice. All reasonable offers will be considered
Please head over the Neyrinck.com and check out how they have turned this into a fully viable HUI surface(I am running it on 2021.12 Ultimate).
