Rare Early Model 1968 Moog Model 950 Modular Keyboard Controller with "Hold / No Hold" Switch


Here is an interesting bit of Moog synth history in via Mike Metz of Thesis Audio Service.

"Attached are photos inside a VERY rare Moog 950 modular system keyboard controller that we are restoring for a client.

This 950 keyboard, made in 1968 was one of the first 950 series keyboards ever made. It has a 'Hold-No Hold' switch instead of the "Glide- No Glide" switch found on later models made after 1969. The circuit has two reed relays nside, rather than the usual one. The first relay closes at key down and produces the standard Moog 'S' trigger for the modular system. The second relay closes at key down also. This relay's contacts are routed thru the 'hold' switch and sent to the sample and hold circuit where they short out the hold capacitor when the switch is set to "No Hold". This way, when you press a key, the standard CV is sent out, but when you release a key, the CV drops to zero, rather than be held by the sample and hold circuit through the release time. This sends the pitch of the oscillator from audio to basically zero when the key is released, making it appear that the note disappears, or "No Hold". Actually, the oscillator will drop to it's lowest frequency, perhaps around 1HZ, so you might hear a little 'putt-putt' noise from the oscillator, but not the correct audio output.

The later 950 keyboards changed the rocker switch function to the more common "Glide- No Glide", yet both keyboard versions kept the same 950 model number. There was no mention of this early version 950 in any of the Moog documentation that I have ever found.

The other fascinating thing about this keyboard is seen in the photo of the bottom of the circuit board. There are hand made scribe marks on the boards around the hand-laid PC traces, probably put there during inspection during assembly. We can't be certain who made these marks on the PC board, but being from 1968....???"

The serial number for this one is 1008.

These aren't common. Only three with the "Hold/No Hold" switch have been featured on the site before, one in 2007, one in 2010, and one in 2011.

New Korg Volca FMs Available in the US


It looks like the KORG Volca FM has hit the states. Several units are currently available via this auction.

"Welcome to the Korg Volca FM, a three-voice polyphonic synthesizer that works in Poly, Mono or Unison modes. It also features octave and transpose controls, along with a velocity slider.

There's also a rotary control for scrolling through different algorithms - to control the interplay between the six operators - and a rotary for selecting presets. Plus, there's an onboard arpeggiator, with a huge selection of patterns and rates available, along with a Chorus effect with just a simple on/off control.

The Volca FM features a six-operator engine attached to a ribbon-style keyboard/step sequencer, the same as the ones found on the rest of the Volca range. A simple set of controls gives users control of the attack and decay lengths of the carrier and modulator signals, as well as LFO with depth and rate controls.

Just like the other Volcas, there's a variety of interesting performance features, which include the usual Pattern Chain, Active Step and Motion Sequencing. This allows users to record automation. With the FM, even the algorithm and arpeggiator settings can be automated, which is very unique and enables the creation of some super out there loops and synth lines.

Connectivity wise, the Volca FM features a MIDI in and the same simple sync ports found on the rest of the range. The FM can be loaded with sounds from the venerable DX-7 via SysEx. While the engine architecture of the FM isn't exactly the same as the DX-7's, it will still load the operator and algorithm settings, which should closely approximate the classic DX sounds.

Features

3 voice polyphonic FM synthesizer
Poly, unison and mono modes
Octave transpose controls
6 operator engine
Ribbon style keyboard/step sequencer
Pattern chain
Motion Sequencing for automation
Algorithm and arpeggiator settings can be automated
MIDI in, simple sync in and out (the same as the rest of the Volca series)
Can be loaded with DX-7 sounds via Sysex"

[Battery Powered EP026] - Like Pixels In The Wind - Wrong Number


Published on Mar 28, 2016 Human Interface

"Complex waveforms like pixels in the wind... Today I tried out the new toy, namely the Teenage Engineering Po-16 which was quite fun. It is a strange little beast and makes you approach music creation in a different way than many other synths/ drum machines. Together with the classic sounds of the Boss DR220E I was able to get a nice little (though slightly sloppy) jam going with a pretty minimal setup.

Also, outside! For many of you on other regions of the planet this may not seem like anything special but way the f up here a nice day like this has been a long time in the waiting...

Oberheim OB-1 Analog Synthesizer SN 0536


via this auction

"The only problem is the OSC 1 Pulse setting doesn't work. There is one knob to choose between Saw on the left and Pulse on the right. No go on the right. It came this way when I bought it. Seller didn't disclose this fact, and I didn't make an issue of it (maybe should have). It doesn't really affect anything in the overall scheme of the sound design. With OSC 1 on Saw, you still get that analog Oberheim sound that's quite distinctive. I've always loved the big sound and versatility of the OB. I also have a Moog Voyager, so that will be handling alot of the sounds the OB can do, but of course, it's not an Oberheim."

MFB Nanozwerg


via this auction

"Real Analogue VCO with CV/Gate + audio in."

"The analogue VCO generates 4 waveform shapes: triangle, saw tooth, rectangle and needle-impulse. The base pitch can be switched over a 4-octave-range, while fine-tune can be specified within a range of one octave. The sub-oscillator with 2 mixable octave settings completes the Nanozwerg's sound foundation. The noise generator can alternatively replace the sub-oscillator to create non-harmonic sounds. Finally, a glide-control can be used to tie notes with portamento.

The state-variable multimode-filter runs with 12 dB slope per octave and offers Lo-, Hi- and Bandpass-modes as well as notch-filtering and resonance up to self-oscillation. Cutoff can be modulated manually, by LFO and by the ADSR-envelope simultaneously. In addition, pitch-dependent cutoff-frequency can be achieved using the key follow function. Finally, LFO modulation can be replaced by the VCO output signal.

The LFO offers 4 waveform shapes including sample & hold as well as a one-shot-function, where the selected waveform is played only once after a gate-trigger, thus imitating a simple envelope. Besides the cutoff-frequency, the LFO can also modulate the pitch or the VCO rectangle's pulse width.

The ADSR-envelope allows modulation of the filter's cutoff-frequency and the VCA-output, with positive or negative excursion. Selectively, the VCA can also be opened by a gate-trigger to free the envelope for exclusive filter use.

For integration into a modular system or use with an analogue sequencer, NANOZWERG offers several control inputs. There is CV/Gate for pitch control and note length as well as CV-inputs for cutoff-control, the VCA and LFO speed. The LFO also offers CV-output.

The audio-input allows signals to be fed into the VCF and VCA. NANOZWERG can be controlled by MIDI from any compatible keyboard or DAW. Note commands are received as well as pitch-wheel (+/- 2 semitones) and modulation-wheel data, the latter controlling the filter's cutoff frequency."

Homemade synthesizer song #1


Published on Mar 28, 2016 organfairy

"I have had a number of requests to do actual music on my homemade synthesizers and sound gadgets instead of just an assembly video and a quick demo.

So, Gentlemen and the occational Lady, now I have done it!

I wrote the music AND build the instruments. If it should be more homemade I should have carved the keys out of wood myself or cast them in plastic (we have a 3D printer where I work so it could be done - but I have used keys from scrapped organs instead).

The rhythm comes from my XOR based drum synthesizer, the bass from the little polyphonic system with sequencer. Both are controlled by the telephone exchange step sequencer. The melody is played on a modular system with a waveshaper I made in 1995, The envelope generator was made in 1996 but has been modified a couple of times since (the first version was not very good because I didn't know much about synthesizers when I made it). The filter was made somewhere in the early 2000s and is light controlled by LEDs and LDRs. The keyboard is only a couple of years old. The solo is played on a simple synthesizer I made out of leftover parts in 1999. It is not completely in tune but that is one thing that has improved over the years: My newest instruments are more precise in tuning. The chords are from a little Oz-inspired mini organ that runs through a stereo phaser. Both are made in the early 2000s.

I hope you don't dislike it too much :-)"
