"Just a quick "run through" of some of the sounds of the elusive GS2 (Well, I tried to be quick about it anyway...). This is one of the 2 early "precursors" to the Yamaha DX line (DX-7, DX-5, TG-77, etc.)..."

"Original lid (legs), pedal assembly, and all the associated leg braces, power cord, and ORIGINAL magnetic sound strips (in their own booklet), and ORIGINAL FLIGHT CASE are included. The flight case is in very good shape, and holds the main unit AND the pedal assembly (please see pics). The included magnetic strips ("Yamaha GS2 Voice Library Vol. 2") are as follows: 1. Harpsichord IV Harpsichord V 2. Percussive Synth Marimba 3. Vibraphones II Glockenspiel 4. Harp Celtic Harp 5. Banjo Electronic piano V 6. Electronic Piano VI Electronic Piano VII 7. Electronic Piano VIII Acoustic Piano IV 8. Acoustic Piano V Honky Tonk Piano 9. Strings III Strings IV 10. String Ensemble II Legato Strings 11. Special Strings Staccato Strings 12. String quartet Brass V 13. Horns Electronic Organ III 14. Electronic Organ IV Electronic Organ V 15. Electronic Organ Pipe Organ 16. Church Organ I Church Organ II 17. Glass Harp Calliope 18. Pan Flute Concertina 19. Gong Splash Gong 20. Tubular Bells Untuned Bells 21. Cowbell/Agogo Bells Electronic 22. Piano-Add Strings Piano-Add Brass 23. Hand Clap Brass Split 24. Bass / Brass Vibe / Flute + 5 blank strips (each holds 2 programs) It's in good to excellent aesthetic condition for its age (again, please see pics), and is fully functional! This is a Pre-MIDI version (the GS2 "MIDI kit" can still be installed if you know where to find one. Due to the vintage of this piece, it is being offered AS-IS. Sounds great and plays nicely (nice keyboard action) [Sidenote: The previous owner told me that he aquired this unit from Bobby Caldwell (of "What you won't do for love" fame (remember him?), though I have no provenance to that effect] Apparently, he was a Yamaha endorsee in the 80's. Once patches are loaded, they stay in backup memory (even if it's unplugged, due to the battery backup) 2 fresh AA batteries installed. A PDF of the owners manual can be downloaded here: (Thanks to "Devicemanuals.com)"

"This is just a quick demo of my first impression with the app "XENON Groove Synthesizer" on my iPad. I was holding my iPhone 4 taking the video and playing at the same time so the video is not the greatest, but it gives you an idea of what the app is like"

The Magic Echo Music GEM Optical Theremin

via Magic Echo Music

"These GEMs are noise making art objects that are so much fun to play and perform with.

It is a single square wave oscillator that changes in pitch depending on the intensity of light exposed to it.

There is an additional LFO (low frequency oscillator) that can be switched on or off to modulate the primary oscillator.

The LFO is a Sawtooth wave that can create tremolo effects while oscillating at a higher speed. There is a speed knob to control its frequency.

There is also an additional CV (control input) 1/4" jack so you can use this with your other analog synthesizer outputs!

Outputs to both stereo headphones and your amplifiers. These GEMs get LOUD.

This video [below] was taken during its prototype stages, so the product looks different. You're looking at the real deal in the photos." Magic Echo Music formerly designed with Health Club Music that brought us the synth on a rope. You can see more of her new projects at www.magicechomusic.com.

EML sequencer refurbishment update

via George Mattson of Mattson Mini Modular. This is a follow-up to the EML Modular Restoration Project.

"The first pic is a repeat of the left module panel I'm making to add to the Sequencer compilation. The second pic is the cosmetically completed left module panel.

I had to take the 16" x 24" aluminum panel, lay out the module arrangement and find a point where I could gracefully cut the panel into two pieces. My oven isn't big enough to hold a 24" long panel. That makes the left panel two parts 'A' and 'B'.

The left ('A') side has two Syntar board PMS1's, a Syntar PMS4 and an MMM VC Filter.

The right ('B') side has another Syntar PMS1 board, two EML exponential amplifier modules, two EML VCO modules, an EML VCF module, an MMM 4x Mixer module, an MMM noise module and two MMM Buffered multiple modules.

The graphics were laser printed in reverse image onto Lasertran and applied to the panel. After baking for about 3 hours, I drilled the component holes then, applied 2 coats of satin spray-on polyurethane. After a day of curing, I added the panel components. I didn't melt off the decal this time with IPA. It was a PITA last time and I rubbed off large sections of graphics. The decal adds another layer of protection and totally disappears under the polyurethane.

Most of the circuit boards are attached. I ran out of mounting hardware and am waiting for their arrival.

The Syntar PMS1 boards consist of a Pratt-Read keyboard driver circuit, a gate generation circuit, a glide circuit, an exponential amplifier, a VCO and a slave VCO.

I made provisions for interrupting the keyboard driver and gate circuitry to allow patching of external 1V/O signals and external gates. I also provide 1V/O outputs pre and post glide simultaneously.

The Syntar PMS4 board contains a VC LFO and a sample and hold. The board will be mounted on panel 2-A and the LFO signals routed to Panel 1-A.

Once I have all of the boards mounted, I'll start wiring up the panel controls. Then, get started on the right panel.
