The Moog 1125 Sample & Hold


Astronauta Pinguim has a post up on the Moog 1125 Sample & Hold. You'll find additional pics, some history on the module, and instructions on how to use it (captured in the bottom pic below).

"The 1125 Sample and Hold is a device that captures the voltage range of the synthesizer, creates a pattern and repeats it constantly. The waveform (sawtooth or random) of this pattern is controlled by a slider on the left side of the 1125 -the other two sliders are a glide and the scale controla. Two knobs in the center of the equipment, one for speed (rate) and other for the sample pattern are located above three on/off switches: one to record and the other two to start and stop the sample (a red light indicates when it is working).
Five switches on the right side complete the unit: one to control the extent of sampling, two on/off switches controls the outputs of the instrument, an on/off switch controls the trigger and another controls the size (short or long) of the gate."

"ARP 2500 and ARP 2600 improvisation
Nothing but analog synths.
i probably should have added some kind of compressor cause some of the sounds kinda jump out at you, but i wanted to keep it raw.. right??"

" weird 40 minute improv with arp 2500 and 2600 simultaneously...hope someone outthere likes it!"

Thaat #1

Thaat #1 by Ashen Actuaries of Asgard
Track featuring the Electro-Harmonix Ravish Sitar pedal with synth & keyboards only.

via Ashen Actuaries of Asgard: "On the structured 'melody' sections of the tune I'm playing a Minimoog Voyager through the Ravish Sitar. On the improv parts and outro, I'm playing a Hohner D6 through the Ravish Sitar. Interesting results.

You can also hear Mellotron Mk. VI, ARP2600, Fender Rhodes, Hammond XK3c and Nord Electro 3 on this one."

Korg PS 3100 Polyphonic Synthesizer

via this auction

"Korg PS 3100 semimodular fully polyphonic synthesizer for sale. Some cosmetic wear, but not more than you would expect on an instrument of it's age. Technically everything is working expect that one of the 12 oscillators (C#) is sending out noise instead of a tone. Probably easy to fix for a tech, and I'm sure that every country has one. Here in Norway there's at least 2-3 good tech's, and judging from the size of my country, every other country should have more of them. The instrument is sold as is. I can ship worldwide, and buyer pays for shipping. The fee will differ from country to country, and allthough I've stated $500, that's just an indication since it's impossible to cover every alternative. Note that the instrument is 230 volt, so you probably will need a converter if you are to use it on 110 volt"

Critter & Guitari Pocket Piano

Note: Auction links are affiliate links for which the site may be compensated. via this auction

"The Pocket Piano is a mini electronic synthesizer with a big sound! The synthesizer features six unique modes:

• Vibrato Synth
• Harmonic Sweeper
• Two-Octave Arpeggiator
• Octave Cascade
• Mono FM Synth
• FM Arpeggiator

The Pocket Piano is housed in a sturdy aluminum and hardwood case and also includes a built-in speaker, a 1/4" output jack, and wooden keys made for a refined touch. It can be powered both by a 9V battery or a 9VDC Power Supply (not included).

When you change modes with the right-most wooden button, a color LED above that button indicates what mode is selected with a different color for each mode. The entire keyboard may be tuned over a 2 octave range by turning the knob second from right. Volume is controlled by the right-most knob. The function of the remaining two left knobs depend on what mode is selected, and are described below. There is also a button that selects waveform (sine, square, triangle, sawtooth) in the first four modes, and shifts the keyboard an octave higher in the last two modes."

EMW-200 Improv by Atomic Shadow

EMW-200 Film from Atomic Shadow on Vimeo.


http://www.atomicshadow.com/
http://www.electronicmusicworks.com/

"An improvisation featuring the EMW-200 from Electronic Music Works. No external effects or processing was used. The main patch contains three sub-patches. The first is the S/H module controlling VCO2 and then fed to the delay module. The second has the triangle wave on the master oscillator and VCO 1 ring modulating in the wave shaper section. And finally the noise output is being low pass filtered and then being ring modulated by the dedicated LFO (which is also modulating the pitch of VCO 1). Each sub-patch is routed to the left and right channels of the six channel mixer.

I am struck by the warm and organic tones that can be generated by this instrument, as well as the sometimes unexpected sounds that can result from very small changes in the controls. In an upcoming video I will be pairing the EMW-200 with some external effects."

I think I spy a MATRIXSYNTH card on the very lower right of the video frame. :)

devsound SJS-ONE Synthesizer


"SJS-ONE is a software defined 8-bit mono synthesizer with a dual (series) MAX261, switch-cap filter, which we are, as far as we know, the only ones to use at this point in a DIY-synthesizer.

The synthesizer has some interesting history that has certainly colored its development and ultimately it’s sound. The initial version was developed as an instructional workshop for a synth-event called SyltJam in 2011. The workshop idea was to show people how quickly you can design the basic hardware and software required to produce a platform for versatile audio and music generation.

As it turned out, people liked it’s sound so much that we decided to refine the design – which more or less involved adding peripheral components to increase configurability and improve on stability and ESD, ground-mismatch and noise sensitivity while keeping the actual design minimal and simplistic.

It’s beginnings are as humble as it’s production – less than 50 of these have been made available and all parts are hand assembled and hand soldered, while the manual is hand drawn and cases hand painted.

Perhaps the most unique aspect of this synth is the choice of digital platform – the Arduino. We did not want to build something static and opted to keep the Arduino instead of adding an on-board microcontroller. Because this will make it so much easier to modify the functionality of the synth firmware provided by us, or to write your own software with a completely unique sound using the vast community support that is available for the Arduino platform.

All aspects of the synth can be fully controlled by designing your own custom firmware and we sincerely hope that people will share their firmware in the spirit of the open source and hardware that inspired us to drive this project from idea to final product.

Host board: Arduino Uno
ATmega328 16MHz
2KB RAM
32KB Flash ROM
Power supply: USB-B 5V DC
2.1mm center-positive barrel 6-12V DC
Output circuitry: 8-bit R-2R ladder DAC
Filter: MAX261
Analog output: ±2.5V signal level (external amplifier required)
Software defined parameters: Waveform
Filter modes
Filter resonance
Filter cutoff
Filter connection (LP, BP, HP)
Filter bypass

You can purchase the SJS-ONE from the DevSound Shop."

"Twentieth visit to the Garden. Composed for Virus TI, Little Phatty and Blofeld"

"The twentieth piece of the HR cycle. To celebrate this number, I decided to use various means of composition. After a small introduction with the Virus TI, the first part goes on with Little Phatty solo lines, 00:41 to 6:11, with a small touch of Virus TI, 0:59 to 1:17, and some drops of Wiener Philarmonik Steinway, 5:00 to 5:53.
From that point, some Virus TI elements of the 19 previous pieces appear in a new configuration to develop at the same time echoes and brand new musical forms. It runs during the second part - with a short background call,(as a night bird call), of Doepfer coming from HR XVII, between 1:39 and 1:45. At 5:27, the Virus Ti vanishes and the end of this part is exclusively composed for Blofeld. I wanted to do something special for this twentieth composition of the HR cycle, and I will of course go on this work in progress since this issue gave me many new ideas."

Inside a Roland Jupiter-4



via Abertronix on Facebook

"Inside of a Roland Jupiter 4. An old but beautiful 4 voice analog synthesizer. Its old so I need to replace most electrolytic capacitors and various other components...

The biggest worry with the Jupiter 4 is that it uses a rechargeable nicad battery to save your settings. The problem is that old batteries have a tendency to leak acid which eats away the copper traces in the circuit. Not impossible to fix but a pain. Im crossing my fingers with this one."

Vintage Synthesizer Sequencer SQ-01 1981

Note: Auction links are affiliate links for which the site may be compensated. via this auction

"Quite a rare quirky analogue synth/sequencer made in Japan by a company called Firstman, which was part of Multivox I believe. Made around 1981. Step or real time sequencer with 1024 notes in total with 16 non destructive memory locations.

This is pre-midi but has full CV control, which is where it works best. Quite a fat analogue sound which produces some lovely bass notes and sounds great in a mix.

CV In/out, clock in/out, gate in/out, footswitch in, Synchro out

Runs on 8x AA batteries or external 12v power supply (not included)

No noisy pots, althougn there are a few surface marks on the membrane keyboard it all works as it should.

A PDF of the operating instructions are available online.

This is built on a metal frame and weighs about 4kg, hence postage of £10 It will be well packed for shipping."

"Diagnostic test has revealed no problems. This was bought as an investment/instrument so I researched and found the first iteration of the synth (made in the US, in fact) because I knew that when it was manufactured overseas some issues came up (voices lost, people having to have to send them back to Alesis to get them fixed. etc.)

Cosmetically it's a 9 out of 10. The only issues are the scratches through the names on the back as illustrated, besides that it's very clean..."

Electronics Today International/Maplin 4600 Synthesiser

Note: Auction links are affiliate links for which the site may be compensated.
via this auction

"All components, pcb, keyboard, casing and internal hardware were supplied by Maplin in semi-kit form.

I personally constructed this in the late 70's , Maplin workshops set up all the boards that required it.

There is still a very small amount of work to do on this synth to complete it, the springline requires wiring in which is approx 4 wires, the joystick also requires final wiring up which is another small job. Anyone who remembers these synths will know about electronics and be able to follow the manual to complete it. The synth did play back in the 70's but I haven't used it since, I also don't have speakers etc now to listen to it on so I'm unable to run it now but there is no reason why it shouldn't work. You may find that some of the tantalum capacitors will require changing, it's usually the case with tants of this age, at least they would pop on my old Nascom which is from the late 70's. There is a very detailed manual which will come with the synth showing all the circuits and construction details, there is also a considerable number of pins for the patchboard. I have removed the back of the instrument whilst taking the photo's of the circuits for clarity, there is normally a back fitted."
