There are a lot of pioneers who had the vision and the skills but not the business savvy. Even Moog had trouble with the vision getting ahead of the business end.

There is no doubt that the 2500 as shown is a mighty impressive unit, but I did some “joe-jobs” for a musician in Toronto in the early 1970s, just for the opportunity to get some experience with the big ARP, and he had that cabinet full with an additional wing cab on the side. This thing was capable of blowing any previous synthesizer off the electrical grid! He eventually built a 64 step digital sequencer to replace the original ARP module.

He actually got so bored of the ARP that he designed a prototype digital synthesizer in the late 1970s.

Google “David McLey” or “Mcleyvier”

The story behind this modular is a bit strange to be honest.

These used to be from Klaus Schulze,former Tangerine Dream member.
Then to have been sold to a German guy who died about 10 years ago.
At that moment the family had these left in the studio and some other guy wanted to borrow these.In fact he wanted to keep them himself,or you can read “wanted to steal” them,from that poor family.
On their turn,the family asked somebody to get the ARP 2500’s back,and he managed to get them back and sold them to me for a very nice price.Allthough the other person who had these in his studio offered the family a ridiculous low price,wich they refused offcourse,thanks to the helping hand and information from their friend who got the ARP’s back in their possession.Now,these are in my private collection and i realy love them.Very versatile and nice sounding machines.
I’ll try to ad some more information in the future.

Can’t argue with that, but count the number of modules in that synth!
