Since the OBXa offerred doubles and splits I've been trying layers of patches, but I'm often disappointed.
OB8 and DX7? Nope
CZ-1 and TX816? Crumbs what a racket.
While I can't say I had the opportunity to try 4 M1K together, I did have 2 plus a M6 keyboard, which was glorious enough.
I also had 2 OB8s at one time, which was superb.
Also 2 OBXa briefly together which was probably my favourite wobbly analog Obie monster.
Dual Kenton MIDI interfaces take some working though.
I managed to get the OB8 and an OBXa together for a while but failed to explore very far.
The Xpander and Matrix are, from my experience more likely to function correctly when you turn them on after a long rest, which is helpful, and the MIDI was sorted by then.
The combination of Xpander and Matrix wasn't as exciting as I hoped, but I didn't spend any time trying to reprogram either of them while they were coupled, which is probably what was required.
If it's not too upsetting for the die-hard Obie fans to hear, I was thoroughly convinced by the MemoryMoog I got to poke around with.
And of course the Kurz K2500 at least can offer a pretty convincing imitation of a few of the above single items.
I may give up on my Matrix 6 too,to provide the funds to get the old OBXa working again.
Curtis chips are not cheap as.
I'm not aware of anyone else commenting on this, but I find the Obie bend and mod paddles to be absolutely perfect for an old guitar player.
I'm up to four of them and their sound rivals anything you can find today.For less than $1500!!ebaYwins201 you can get 24 voices (48 oscillators) of unique analog goodness. While 6 voices in mono is pretty amazing, having 6 voices in stereo (one left and one right) is astonishingly awesome. Having 12 or more voices polyphonically (in group mode) is practically non-existent in modern synthesizers (except DSI stuff).My advice is to watch eBay for awhile and get a feel for what the offerings are, them just Buy It Now when you see one you like. -pc,___
