Tube Noise Generator
images via this auction via wattson.
"This is a tube noise generator, radio frequency, mute, audio frequency, LF, and ASA is some sort of other noise that im not sure what it is, you cn make some really cool hats and crashes with this thing, the VU meter tells you how many volts you are sending out and you can control that by output knob. the rear of the unit has a 1/4 line level out and a rca line level out. i took detailed pics of the inside, the way the noise is generated there is a tube placed between two magnets its a really neat circuit."
More of a bit of test equipment, but interesting nonetheless.
More info on these here.
"A device that produces electrical noise for use in electrical measurements. Electrical noise generators are commonly employed to measure the noise figure or noise temperature of radio receivers. They are also used in various other tests in radar and communications systems. Celestial noise sources are used to calibrate large antennas."
Update: here's a video of the unit by Shagghie previously posted here.

Oberheim OB-Xa
images via this auction via Matt.Be sure to check them out full size; they are fantastic shots.
via the auction:
"Personally, I think the OB-Xa holds more 80s nostalgia in its tone than any other synth of its era.. It has the most joyous and rich, vibrant signature. Aside from being most famous for "Jump" it can be heard on countless numbers of 80s pop records, as well as 90s club and electro/house/pop/italo recordings up to the present day.
This one has a quite rare Real World Interfaces Midi upgrade, built and installed by Robin Whittle, best known for his Devilfish modifications to the 303. The strip along the top of the keys is a guide for the midi features, and the switch and black button is to toggle midi mode. The manual for the midi upgrade is included. Its a clean professional modification, and anyone who knows Robin's work will tell you he is the best."
EMSA -- Electronic Music Studios of America

via David:
"Peter Forrest's post to AH about EMSA led me to do a little digging. I lived in Amherst, MA, years after EMSA but still love the area. Anyway, Everett Hafner's (owner of EMSA) daughter put up a page about him, including a seriously photo-laden picture of EMSA stuff"
Update: Be sure to check out the EMSA link below for all posts featuring EMSA - there are only a few including this one, however there is some fascinating history including the Ionic Performer.
Stribe 0.4a w/ 0.4g Max patch + DSI monosynth
YouTube via soundwidgets
"A mini-demo of the very basic Max patch I wrote for the Stribe. It's essentially a 'virtual stribe' that sends display messages to the Stribe, and receives sensor data from the touchstrips and displays that in rslider controls. You can actually play with the virtual stribe without a real Stribe, but it's just not the same."

How to Repair a Poly-61
"Welcome to my documentation of the odyssey repairing some Poly-61s, as i recently bought 3 of them with the intention to get at least 2 of them working perfectly. If you want to repair a Poly-61, i have to warn you - it is quite a lot of work to get it perfectly working again, if it has the full repertoire of usual problems of this synthesizer. First of all, if you don't want to do a full restoration, you should know a bit about the inner workings of the Poly-61. This is where i want to start. So let's have a look at the anatomy of the Korg Poly-61."

Continuous Signal Processing: The Fourier Series

via AH regarding the following question:
"Does anyone know the formula for calculating the resulting harmonics the formula for calculating the resulting harmonics of a pulse wave when the pulse width is varied? In other words, a square wave (or pulse wave with 50% duty cycle) has only the odd-numbered harmonics present; how do you determine the harmonics present when the duty cycle is 25%, or any other value?"
Dave Manley followed up with a link to this site.
"This brings us to the last member of the Fourier transform family: the Fourier series. The time domain signal used in the Fourier series is periodic and continuous. Figure 13-10 shows several examples of continuous waveforms that repeat themselves from negative to positive infinity."

Roland TR-909
"The Roland TR-909 Rhythm Composer is a partially analog, partially sample-based drum machine built by the Japanese Roland Corporation in 1984. It features a 16-step music sequencer and a drum kit that, at that time, aimed for realism and cost-effectiveness. It is fully-programmable, and like its predecessor, the TR-808, can store entire songs with multiple sections, as opposed to simply storing patterns. Only around 10,000 units were produced.
The drum machine is in perfect operating condition, all knobs work and buttons properly trigger drum sounds. Some drum sound knob pots are scratchy which is common with a synth of this age but can easily be cleaned or have knob pots replaced. Once you set the drum sound you want, and stop moving the knob, the sound output is loud and clean."

Note on Auction Posts
In the comments of this post, Mr. Array noted that a useful thing to have for auction posts would be the amount the item went for. I actually think it's a great idea, however personally I can barely keep up with the amount I currently post. I do have a solution though. If anyone happens to click on an auction that has ended, note the price it went for in the comments of the post. That simple and that easy. I'll do the same, but I can't go back and make a job of it myself. 20+ posts a day takes a LOT of time and the rest of my time goes to my day job, family and a little bit to myself for actually playing synths.
So... if its easy enough for you to do it, do it. If not, then obviously don't. Worst case, things remain the same. However, if we start getting the closing prices for auctions we will be able to use the site as a resource in looking up what things went for over time, just do a search for the synth and the word auction and all auction posts for the synth should come up. Check the comments and find the price as well as other people's comments.
BTW, does anyone know how long closed auctions stay up on Ebay? While they are up you can still search for what items went for on this site. I don't think Ebay let's you search on closed auctions.
Udpate via the comments: you can search old auctions under the advanced search in Ebay by checking "Completed listing only" however you do have to be logged on.
Also, this post applies to the auctions on Matrixsynth-b as well. If you feel like nothing the ending price in the comments, go for it.

Roland Ace Tone Top-1
"Fabulous-looking and displaying synth/organ made by Ace-Tone, the predecessor of Roland. This is the Top-1 organ, which utilizes what sound like sawtooth waveforms to generate tone. It is polyphonic, but I have no idea if it's analog or digital. I'm guessing the latter, since analog polyphony didn't really exist in the '60s. [I'm guessing analog divide-down technology - if you know, feel free to comment]. All I know is this thing looked great set up next to my tiki mug collection, but the girlfriend has decreed that it is time to make room her our ever-increasing pile of makeup and tampons or whatever.
I've seen a few of these organs listed over the last few months, but this is one of the few units that comes with a music stand and almost perfect operability. And as I said before, it looks great. I know that you are attracted, magpie-like to the shiny, shiny red brilliance of this vintage classic. Just bid on it and get it over with, so you can sleep tonight without obsessing."

LinnDrum II on Roger Linn Design
The LinnDrum II is now up on Roger Linn Design. via MG."In January 2007, Dave Smith and I (Roger Linn) pre-annouced BoomChik, a new drum machine product that we are creating together. Since that time, we received many enthusiastic comments and suggestions from musicians around the world that caused us to rethink and enhance the product's design. The bad news is that this design change (along with Dave's release of Prophet '08 and my release of AdrenaLinn III) has delayed our development. The good news is that the product has grown into a far more capable instrument. Also, we've decided to change the name to LinnDrum II, recalling an innovative drum machine from a bygone era. Please read on for more details.
There will be two models: the all-digital “LinnDrum II”, available from Roger Linn Design and the “LinnDrum II Analog”, which adds four voice analog synth voices and 27 dual-function voicing knobs, available from Dave Smith Instruments. We're currently estimating street prices of around $1000 for LinnDrum II and around $1500 for LinnDrum II Analog. Here's a brief summary of the product features:
Features common to both products:
* Operating system is optimized for realtime live performance, with the ability to switch between beats, drop in and out of record on different beats, switch in and out of song mode and much more, all without stopping play.
* Digital voices have nearly the same signal and modulation path--including modulated filters and resonators--as shown on the LinnDrum 2 Analog panel. Total number of voices is not yet determined.
* 16 standard 1.1 inch square velocity and pressure-sensitive drum pads, assignable to sounds, tunings, beats, track mutes, pad mutes or sequence steps.
* Both MPC-style real time and 808-style step recording are provided, and the 16 pads are backlit for visual animation.
* Real-time stereo digital effects on output mix--modulated multi-mode filtering, guitar amp model and bit/sample rate reduction distortion, modulated resonator, compressor, deley, reverb and EQ--with 6 dedicated on/off keys to switch them individually in or out in real time.
* Compact flash slot for data save/load/backup, or for expansion of internal sound storage.
* Internal RAM and flash size is yet to be decided; at least 16 mbytes for each.
* 128 x 64 dot graphic LCD.
* USB port for transferring samples and other files, MIDI messages and audio I/O to and from computer.
* 4 pushbutton soft knobs below the LCD, acting either as soft knobs or soft keys.
* 52 lit buttons for extensive real-time performance control.
* 2 sliders assignable to a large variety of real-time functions.
* HELP key gives descriptive text for any screen, data field, function key or knob.
* Pressing DETAILS key followed by any panel key presents a screen of settings related to the key pressed.
* 2 pairs of stereo outputs, with phones output fed from either pair.
* Stereo inputs for sampling, audio processing or triggering sounds.
* MIDI in and out.
* 2 inputs for either foot switches or expression pedals, assignable to a wide variety of functions.
Additional features on Dave's LinnDrum II Analog:* Four complex analog voices based on the same Curtis-chip synth voices used in the highly-aclaimed Prophet '08 and Evolver keyboards.
* Four direct ouputs for the four analog voices.
* 27 dedicated dual-function rotary encoders for voicing the analog and digital voices.
There's still a lot of work to do so late 2008 is our best estimate of when the products will be ready. If you'd like to be updated on the progress and informed when we're ready to ship, or if you have any comments or suggestions, please send us an email. And to all those whose comments and suggestions helped refine our design (special thanks to Noaka for help on the visual design), please accept our sincere thanks.
Thanks,
Roger Linn"
