MAKE magazine wrote about this low-cost MIDI interface
The MIDITRON, basic version only $149. Up to 20 inputs for keys or buttons, or 10 analog inputs. They even have a wireless version for $399. If only it had more like 32 digital inputs.
Ray Wilson makes his own “Stylophone”.
Yves and his “Ivanhoe I” homebrew modular synth
His website hasn’t been updated since November 1998…. Does anyone know what happened to him?
His site’s continued existence is a miracle–it ought to be preserved.
“Winnipeg is a Frozen Shithole” by Venetian Snares.
Song titles are (no, I’m not making this up):
1. Winnipeg is a Frozen Shithole
2. Winnipeg is a Dogshit Dildo
3. Winnipeg is Fucking Over
4. Winnipeg is Steven Stapleton’s Armpit
5. Die Winnipeg Die Die Die Fuckers Die
6. Winnipeg as Mandatory Scat Feed
7. Winnie the Dog Pooh
8. Winnipeg is a Boiling Pot of Cranberries
9. Die Winnipeg Die Die Die Fuckers Die * Spreading the Hepatitis SKM – ETR Style
Heh. Perhaps he doesn’t like Winnipeg.
It’s amazing what you sometimes find on Deviant Art…….
…….in between thousands of badly-drawn furry and anime comic characters.
BTW, I don’t think Matrix or Music Thing have featured this guy yet. Good panel artwork, esp. for a 16-year old kid from Chicago. Looks like a FatMan board inside. Wonder if he ever finished it.
More on this later…..
Daddy, what did “Electronic organ” mean in 1950?
Well, dearie, it meant something like the Baldwin Orgasonic:
Thirty-six 6SN7s as oscillators and dividers.
(I estimate that the tube heaters alone consume about 200 watts.)
A 6L6 amp with a field-coil speaker.
Total weight about 500 pounds.
One of the rarest pieces of vintage 1950s hi-fi
It may not look like much to you. But this is one of the first-ever products of the Fisher Radio Corporation, and is so rare that no hifi collector that I know has ever seen one–or even an ad or catalog listing for it. This particular one was found recently by John Eckland at a Palo Alto garage sale. Made circa 1953. It is a copy of the more-common HH Scott dynamic noise suppressor, made with miniature instead of octal tubes. The “Eye” tubes on each side of the panel display the operation of the bass and treble noise gates, respectively.
There was a special amplifier for it, but John didn’t find the amp chassis. So he will pair it with the Fisher 60 triode amplifier seen in the 3rd photo, for some historical parity. Imagine a home hi-fi system using this stuff, plus a large rackmount preamp, perhaps a rack-mount REL Precedent FM tuner, and a Rek-O-Cut turntable with a GE variable-reluctance magnetic cartridge mounted on a massive Gray tonearm. All feeding a huge Altec Voice of the Theater horn speaker. Top-end for 1953.
Last Sideman photo–a major weak point
An old organ technician told me something amusing. He says that the relay shown here is a MAJOR weak spot in the Sideman’s design. It was custom made for Wurlitzer, it’s a high-impedance coil that burns out easily, and replacements are impossible to find.
It has 12 poles–ever tried to buy a 12-pole relay?
The fix is even more stupid. All this relay does is to enable the drum pattern (via the START knob on the panel). Simply hold the relay closed with a rubber band, and control the output with the volume control. But people who find old Sidemen rarely think to try this….
Wurlitzer Sideman – another view of the “sequencer”
If only one could buy such a mechanical monster today — preferably with MIDI output. I was told that lots of Sidemen got scrapped simply because that rubber belt broke, and the owners were too old/senile to get it fixed…..sounds like ageism to me.
My question is: 50 years from now, will you be able to plug a modern digital drum machine, and find it still works? Hah.
closeups of Wurlitzer Sideman
The electronics chassis. Tube complement is one 6AV6, two 6C4, one 6BA6, and five 12AX7s. The trimpots control the resonance of the bandpass filters that make the drum tones. “SHIMMER GENERATOR” controls the decay time of the noise-based cymbal sounds. The inside of this chassis is quite impressive. Maybe later. (Does anyone out there have the schematic for the Sideman? Just curious. Repairing it is straightforward, but how this thing works is becoming interesting to me.)

This is the control panel. It’s quite difficult/costly to get that kind of chemically-etched brass panel made today. The BLOCKS and CYMBALS knobs are rotary selectors that provide five different variations for block and cymbal patterns, plus totally disabling them. I must assume some of those home organists found a use for this–because the amount of switching required to implement the function is frightening. Above the start and volume knobs are two neon lamps that flash in time with the rhythm.
More of the Sideman internals
Here is the left side. 9 tubes in the sound section, and a power amp made with a 12AX7 and two 6BQ5s. 2-way speaker with two tweeters, one coaxial with the woofer and the other on the front of the cabinet, under the control panel. The big aluminum disk turns the contact arm–it is driven by the motor thru a rubber belt and a rubber idler wheel. The speed slider on the control panel drags the idler on the disk, closer to the center and the rhythm runs faster. Power is shut off by pushing the slider all the way rearward. All the tubes in this thing were original, dated 1958, and still good.
The world’s first electronic drum machine–the Wurlitzer Sideman
I’m fixing this one for a friend. Introduced 1958. In this view we see the “pattern sequencer” — a large printed circuit board (the only one in the unit) with a set of contacts on a rotating arm. The contacts close circuits and generate trigger pulses, which hit vacuum-tube ringing filters to generate most of the drum sounds. This unit was in remarkably good condition, if you don’t count the ugly black padded naugahyde someone put all over the outer cabinet.
old circuit-bent keyboard
This was a horrible Chinese combo keyboard (no brand name) I found long ago, at a Longs Drug store for $5. It contained exactly one chip on a tiny PC board – plus a lot of buttons and a 3-octave keyboard. I cut it down and installed it in a small box. Switches allow you to misconfigure the scanned function-selector buttons, the knob drags the pitch waaaay down. Instant Skinny Puppy happy pop music. Runs on 4 AA cells.
