New XPander Sides by James R. Coplin

Via James R. Coplin on AH:
"I have been annoyed that my Xpander has to sit flat and takes up a bunch of
valuable horizontal surface in my studio. I do have extra vertical space so
I though it would be great to make some new sides for the Xpander so that it
could "stand up".

You can see the results here:

Works perfectly! I made mine out of 1/4 sawn white oak and finished with a
Mission style / Stickley finish. The color is pretty much exact to my
original sides. The stainless screws are just temporary until the black
hardware arrives!

Since I know people are going to ask, yes I will make these for folks and
they are super easy to install. The price is $75 plus shipping for standard
hardwood (oak, maple, etc.). If you want some funky colors, it's not a
problem but will run an additional $16 for the dye. You can see the
available color options at:

http://www.homesteadfinishing.com/htdocs/TransTint.htm

The color on mine is the Dark Mission Brown. The red desk you see in the
picture is the Bright Red dye.

This is not a chump finish either, it is a traditional oil finish with hand
cut shellac and a hand oil rub out. The look and feel is silky and perfect.

I can make these out of more exotic or highly figured wood as pretty much
anything is available to me but expect about a $25 additional charge
depending on the wood you are interested in. I can also make standard
Xpander sides if you just want to spice up your Xpander or replace a beat
set on your current. The price is the same as there isn't much less wood
and most of the cost is in the labor. I can also make sides for any other
synth you would want, just get in touch with me. Thanks!

That looks like a Synthi to me.

Yamaha Electone "Synths"

Video of the Yamaha D-80 by Mattias. I always seem to forget that some of the Yamaha Electone home organs had synth sections and with the D-80, an arpeggiator as well.

Frank who is an Electone enthusiast posted the following on AH and gave me the ok to put it up here:

"I've got the 415: image

which is probably the last of their analogue spinet organs.

Very cool machine. The solo synth on mine sounds very SY-1 or SY-2'ish. You can have pitch and/or filter mod with left-to-right wiggling of the solo section keys too. It takes a little getting used to, but once you get the hang of it, it can be pretty expressive.

The strings, with soft attack and longer release, through the synphonic ensemble (BBD ensemble) or the rotary speaker (!) can be very pleasant.

Jeff Koepper tried mine a couple of weeks ago and got all sorts of cool un-home-organ-like things out of it.

Yamaha made a whole bunch of these kinds of miniature three manual organs with solo synths in them. Earliest is probably the DK-40, then at least there was the D-80, D-85 and 415. The D-85 and 415 seem to be nearly identical, feature wise.

The DK-40 is technologically not too distant from the earliest group of Yamaha analogue organs, and I suspect it shares similar circuitry to the YC series of organs.

Also, the DK-40 has a 'fourth' manual, in the form of a separate 'portamento' synth, which is played from a ribbon controller to the left of the solo synth keys. You can just barely see it in this image the green tabs control the portamento ribbon, which extends right in front of them.

I kid myself that the 415 is sorta like a cut down EX-1. It isn't really, but it's fun to pretend, and I don't anticipate ever owning an EX-1, for a number of reasons! :-)

Update via buckystoppz in the comments:
"I also have the 415 and use it to death! People are sleeping on these, I got it for $120 on eBay locally. They were about $8000 new in the early eighties."
