During the 80's the Ultimate support and Knights tube stands were the choices if you used more than one keyboard plus drum machines, table top sound modules and mixers..
For a while I needed to hold 2 keyboards , plus another for bass.. a couple sound modules , a drum machine and a mixer..
Uncle Dave and I came up with some interesting configurations..
BTW: my gear was split between Roland and Yamaha, and a Korg module..
Yamaha TX 81z for tine piano DX7 sound.
Yamaha rx123 drum machine.
Roland JX10 main keyboard
Roland Juno2 for color sounds.
Roland SH101 for bass.
This was my favorite set up at the time.
The keyboard stand was so adaptable .. changing keyboards was easy...and we did change often...ALL Brands...
