New Yusynth Quadrature VC-LFO

via Yusynth where you'll find more details - look for the red blinking led.
"The quadrature LFO is a special module that was not found on many modular synthesizers back in 1970s. Mostly, only companies like Polyfusion, Buchla or Serge would propose such a weird LFO.
Basically, it is a sinewave LFO with four outputs which are running at the same rate but are phase shifted by increment of 90°. That is, the first output has a shift of 0°, the second 90°, the third 180° and the fourth 270°.

What is it useful for ? Mostly it is for modulating simultaneously up to four sources at the same rate but out of phase. This makes it possible to achieve so called "Barber pole" effects or "Shepard tones". For example, imagine that you connect each output of the Quad-LFO to the V/oct input of four different VCOs, then you'll hear continuous though steady (paradoxical, ain't it !) rising and falling intermangled pitches (see ,).
It can be used also to drive four VC-panners to create rotating sound effects that fill the stereo space.

The core of the circuit is based on the quadrature oscillator circuit of Ian Fritz's ChaQuO chaos oscillator . I modified it in order to have voltage control of the frequency and also I added buffers with output LED indicators and a toggle switch that makes it possible to exchange the phase of the 90° and 270° signals in order to change the direction of the phase rotation. This simple trick is very handy when performing "barber pole" modulations.
Each LED show the positive part of the corresponding signal, they are organized on a circle to visualize the phase differences between the signals."

Organ Synthesizer Crumar Organizer T2

via this auction

"The Crumar T2 is a great tool. The sound is very special. While a relatively soft sounds of the Hammond Crumar T2 can be quite lively effect. The percussion will be a switch or turned off via a 9. With 2 drawbars to the strength and the echo of the percussion be set. It is not a single keyboard percussion which also has its appeal. The lower manual has no percussion. For Pedal Bassynthi is installed."
