cwejman vc forward compressor

via this auction

"The VC-FC is a unique forward compressor in the sense that all compressor parameters can be voltage controlled from the external modulation sources by CV inputs. It gives a lot of possibilities for an instant change of compressors character by CV signals from analogue sequencers or other CV generating devices. The external devices, such as filters can be also inserted in to the Side Chain of the compressor for frequency dependend gain reduction.

MODE/ variable threshold
The threshold from which incoming signal is compressed is variable in the range from -15 to +15 dB.

MODE/ constant threshold
The gain of the compressor is variable in the range of +24 to -6 dB with a fixed output level at +6 dB at maximal ratio.

KNEE
Knee can be set for a sharp or soft character of gain reduction ((imitates the vintage opto compressors gain reduction) by manual selector or by CV signal with two states; 0 for sharp knee and +2 Volts to 10 Volts for soft knee.

RATIO
The compression angle is variable (by knob) or by CV signal from OF (no compression) to limiting (almost infinite compression)

ATTACK and RELEASE
Attack and release time are controllable by knobs or by CV signals in a wide range for all possible musical applications. The Attack Time; from 200usec's to 250 msec's and The Release Time; from 20msec's to 8 sec's.

MAKEUP GAIN
The Makeup Gain is controlled by knob or by CV signal in the range from -15 dB to +15 dB"

Verbos 258v dual oscillator (buchla format)

via this auction

"
This is apparently one of the early 258v's that Mark Verbos made. There are two flaws with these early models.

- The screen printing is slightly off, so the lines don't line up with adjacent modules as can be seen in the photo. Not really a problem except for those who are OCD about such things.

- Additionally, it's a very tight squeeze on some cases due to the screw holes being a tiny bit off. It fitted in my 201-4 rack without any problems, but in my 24 space system, I couldn't line up the top holes (as can also be seen in the photograph). This may or may not affect other peoples systems, as there seems to be some very slight variation between spacing, and tolerances.
Worst case, you can use it like I have the last year by just screwing it in with 2 screws, and holding it down when removing jacks.

Other than this, it works just fine, and sounds fantastic. It's amazing for deep boomy bass noises, and the FM sounds that come from it are crazy.
I'm only selling it because I have several similar oscillators in my eurorack system, which I turn to for this kind of sound.
I'd love to keep it, but 200e boat space is at a premium :-)"

Livewire Dalek Modulator

via this auction

"the first module in the alien modulator series, the dalek modulator contains 2 linear cross-modulating vcos and a ring modulator in one module.

the ring modulator's carrier and modulator inputs are normalized to the internal vcos, but either or both can be replaced with any external signal. vcos feature internal cross-modulation, horizontal symmetry control, sine and square wave outputs and can be used independently of the ring modulator.

specifications:
inputs: cv modulation of frequency with attenuation, carrier signal input, modulator signal input.

outputs: carrier vco output, modulator vco output, ring modulated signal output.

controls: carrier & modulator vco controls for frequency, horizontal symmetry, hi/lo speed selection, waveform selection and cv modulation attenuation. each external input has selectors for ac/dc coupling. modulation can obey or destroy"

VTECH MUSIC MAJOR

via this auction

"This super cool electronic piano was designed to teach children music. It has 23 keys, 6 different keyboard patterns, 10 sound affects, 5 learning exercises, 12 different rhythms, and a tempo control . When you press a key, a corresponding red light appears representing the note on the music tablature screen.

Sounds:
This electronic piano TALKS!! Much like a speak and spell, the machine will ask you to perform tasks. When you first turn it on it asks, "Please choose an activity." Some tasks it will say "NO, try again." or "YES, you are right."

There are 7 different overall sounds the piano can perform as, piano, organ, flute, cello, trumpet, and voice.

Along with the regular piano keys, there are 10 sound effects keys. You can make a sound like a dog, fish, cow, goat, bird, and various percussion sounds.

But the COOLEST SOUND this piano makes is the voice function. If you press the little red button that looks like a face, the piano will function as the scales. Press a key and the piano will say, in a human-like voice, "Do, Re, Me, etc..."

The piano also has 12 different rhythm you can choose, including Bassanova, Disco, Rock 'n Roll, and others. There is also a tempo button that fluxuates the speed from pretty mellow to normal to super fast, nearly machine gun fire quality.

The demo function is cool. You can choose a song and the piano will automatically play the song and the corresponding notes lighting up on the screen.

Mechanics:
Manufactured by in the year 1986 buy the company Video Technology Educational Electronics or VTECH.

Takes 6 C batteries. there is no corrossion in the battery compartment. It also takes an 9V 500MA electronic adaptor.

Apparently, this machine holds some memory capacity; there is a record function...

If you're into circuit bending, the keyboard seems somewhat easy to get into."

HQ Disco Video Clip - DOCTOR WHO TV THEME

YouTube via funkyboymark | January 24, 2009 |
Some synth spotting.
"From British TV Show Top Of The Pops from 1978 this was the disco version of Ron Grainer's theme to the DOCTOR WHO TV series by MANKIND, produced by Don Gallacher and arranged by Mark Stevens. The late 1970's period was very strong and competitive for music as record sales of the whole top forty were massive back then compared to today and although this only managed number 25 on the UK charts it still sold a fair few copies and hung around for 12 weeks and was aired on the show two or three times. This particular clip is from 31st December 1978.

This video is uploaded only for promotion of the disco era and the music of Mankind, Ron Grainer and Doctor Who and I will gladly remove the video clip if requested if it's in breach of any copyright."
