Hi Ian,
Ten keyboards may have been a little excessive, but the more the merrier I always say. Truly though, I made use of all of them. Like I mentioned above, there were many times when I was playing one of the analog synths while programming one of the others for the next song coming up. The floor space I ate up did limit the clubs we could play, so there were times when I would scale it down. But man it sure looked cool when everything was there.
The Mellotron was one of the neatest instruments I have ever owned. And as long as you maintained them properly, they were fairly trouble free. The biggest problem I had was tapes wearing out. Which is why I installed the 1/4" tape kit. Instead of the 3 head block positions of a stock Mellotron (standard tape set was Flute - Strings - Choir) the kit allowed for 4 positions which is why I used a Tascam 2340 7" reel deck which was a 4 track recorder. Recording the tapes was easy. The lengthy process was cutting the tape to length and spooling it and installing the spools into the tape frame.
Yes, that's me with the Promega 3. It was and still is an incredible instrument. Thanks for the kind words regarding the demo video.
Dave
