Moog Prodigy Vintage Synthesizer

via this auction
"Way back when I was hot to get my first real synthesizer Moog introduced the Prodigy as an alternative to the Mini Moog. I bought mine around 1980 from Washington Music Center and it served me faithfully as a great left hand bass for many years. I used it only occasionally for synth leads so I never really explored it's capabilities but I can tell you it produces an amazing copy of the Hammond Solovox (which I also own) solo on

"Palisades Park"... Some of the Prodigy's I've seen have a reddish stain to the wood, mine is the earlier light brown finish."

Casio CZ-101

via this auction

"Casio's own take on digital synthesis from the mid-eighties and is found in all of their CZ series. You basically modify digital waveforms (sine waves) to create various sounds. It can create wild new sounds, notably percussive sounds."

ROLAND JUNO 106 Programmable Analog Synthesizer

via this auction
"The JUNO-106 is a 61-key, 6-voice completely poly phonic synthesizer that produces superb sounds comparable with that of the famous JUNO-60. The DCO keeps pitch exceedingly stable at all times. The JUNO-106 features a Portamento function for the first time in this price class. This allows the JUNO-106 to produce polyphonic Portamento. Like the JUNO-60, a Chorus effect is provided to re produce realistic string sounds or full-bodied organ sounds. Up to 128 timbres can be memorized. There are two groups (A and B), 8 banks in each group, and 8 patch memories in each bank. A cassette interface is provided for infinite data storage. Groups A and B can be loaded or saved independently so that the user can combine data as he wants. MIDl jacks are also provided. MlDl channels (1 to 16) can be assigned, and MIDI information can be selected by the Function switch. This operating information includes LFO Modulation, Bender, changes in patch memory, and keyboard information. The JUNO-106 can be connected with other MIDI devices to expand the system."

Doepfer A-127 VCRF filter

"the Doepfer homepage about the A-127 Triple Voltage Controlled Resonance Filter:

Module A-127 is a triple resonance filter unit. It contains three separate voltage controlled band pass filters. Each filter has it's own LFO (triangle waveform) with LED display and adjustable frequency and amplitude. Instead of the internal LFO an external control voltage may be used to control the filter frequency. In this case the external voltage is fed into the external CV jack (with integrated switch to turn off the LFO signal) and the amplitude control of the LFO affects the level of the external CV signal. Each filter is equipped with the following controls: LFO frequency, LFO/external CV amplitude, filter frequency, filter resonance and filter amplitude. In addition to the mix output for all three filters each filter has a separate audio output. The original audio signal can be added to the triple filter mix signal with a separate control. All of the 3 filters share a common audio input with attenuator. The filter audio inputs are very sensitive so that distortion may intentionally be used to create new sounds - if desired.

The frequency control range of the bandpass filters is about 40Hz...6kHz, the frequency range of the LFO's is about 0.02Hz...20Hz (= 1 min ... 1/20 sec per cycle).

Each of the three filters can used also as a 12dB low pass (with resonance control) instead of band pass. For this a jumper has to be changed on the filter board in question. In this case the module can be called no longer "resonance filter" but "triple low pass filter". It is also possible to modify only one or two of the filters to low pass.

The A-127 is a versatile module for sound modification. Here are some application samples:

* reproduction of resonances (fixed filter frequencies, resonances and amplitudes)
* triple internal or external CV controlled sweeps for very complex filtering
* filter effects similiar to vocoder and/or synthetic speech using specific external CV's to control the three filter frequencies (e.g. coming from the Sequencer A-155 or MIDI-CV Interface A-191)
* MIDI controlled filter settings or sweeps (e.g. in combination with A-191)
* random filter sweeps using random voltages (e.g. from A-118)
* triple S&H filter effects (in combination with S&H A-148)"
