Texas-based Syntaur is one of the better sources in the nation for synth and keyboard parts from vintage to new. If you're a vintage gear hound and no one else has that unique knob or custom chip you need to get your eBay find sounding like new, chances are they do. They also do repairs for clients all over the world in-house.
A story about a repair shop normally wouldn't be very exciting, so they countered this by bringing some exciting custom synths to NAMM. First up is a 1975 ARP Odyssey that's been fitted with sub-oscillators on not one but both of its VCOs. The result is bass you'd associate more with a Moog, underneath the signature tweezy ARP sound that people seek out precisely because it's not a Moog.
Next is a Roland "Juno-107." Upgraded voice chips create a fatter sound, and then there are those cool led-tipped sliders. But the real killer feature is patch sweep, which makes the machine cycle through the eight patches in any bank. Hold a chord and you get a wave-sequencing-like effect, which could be further optimized by intentional ordering of your patches. The rate is adjustable, but no word on whether it syncs to MIDI clock, though I'm sure they could make it do so if they wanted.
The 107 is a one-off for trade shows, but if you asked them really nicely, maybe they'd make one out of your old Juno-106. More synth news from NAMM is yet to come!
