Thanks for the nudge, @jimmarchi1.
I actually wrote a reply to @iplaykeyboard's post the day it dropped, but the site was having forum technical issues that day, and my post wouldn't err... "post"... so here we go:
I remember that day, I tried to reply to someone else and it failed so I saw this and just shelved it hoping someone else would have a better idea than I did.
As for my personal experience, I got burned by wobbly keyboard stands in college and quickly switched to the nuclear option of that era, which I am eternally happy with and will surely outlive me. It folds to fit in a bag, but I wouldn't want to have to carry that bag very far -- MFer is beyond heavy.
those Z jawns are solid... there's this guy Jim Daneker I know who does Arcade Orchestra who has some new stand he's always into, I should check his facebook or give him a hollar
I do have too many keyboards, but i'm never using more than 2 at once.
you and me both, but I can't part with any of them, every time I think of dumping a few I use them and remember why I love them... it was big concession to abandon all my FM keyboards and go down to modules and rack units, but needs must, too many analogs and hybrids that don't come in module form... the keybed on the proph600 is so crappy but I like having it and the behringer clone is so much less buttery, its close but harsh and shrill unless you keep your patching conservative, and my 600 was recently serviced
But to Jim's point, I personally go for the approach he's leaning towards at the end of his reply: with 2 keyboards, I keep them both at the same level/height and arrange them side-by-side, in an wide "L", or just one on each side of me. Elevating my arms dramatically to perform on one, then lowering them back down to perform on the other just always feels unnatural to me. People do it, but it's just never been my thing.
I use 2 tiers when I must, but I pefer to build an L or U with a tier here or there for a mono where it bothers me less to reach up for single note runs or tweaks while I'm running a sequence or arpeggiation. I'm not a great keyboardist, its my 4th or 5th instrument, so having my right and left hand at 2 different heghts throws me off on all bust the simplest parts. During peak trash godz before mike got cancer when we had the commercial space behind his row home for our base of operations I had thise enormous C shaped rig setup with various keyboard, sequencers and modules and it was BLISS. I had a 2nd teir on 1 stand with my polysix and prophet stack but I was using the p6 as the master controller and had the proph tilted so I could tweak it. I ahd this whole stacked pad thing happening or soemtimes I would have 1 running the arp. then I had an odyssey, circuit monostation, some korg Q1s, the pittsburgh modular and often something mid sized like my mopho or prologue 8 for options. I had a rack under the big 80s polys with a tx81z, mks50, rack eared modal argon or yami with the physical modelling engine and bass station rack and some decent fx units into a rane rack mixer for when I wanted to get stupid. I had one of my edirol midi patchbays in there to distribute from all the other other devices as needed and it was also my clock distributor, I would take my clock from mike's squarp pyramid, midi went there for distribution and I after a brief flirtation with the squarp gate out and a clock filter module I just started taking my analog pulses from the circuit because its hella stable. Most solid analog clocking I've ever used.
