R54 MetaSonix Eurorack Module

via this auction
"this is a brand new module, never racked. barely used. the r-54 uses a triode-pentode in a unique wien-bridge circuit, to provide clean sine-wave oscillation. using a vactrol, the pitch of the r-54 is sweepable from less than 20 hz to more than 5 khz, continuously, via front-panel control or a cv input. by adjusting the waveshape/resonance control, the sinewave signal produced by the r-54 can be trimmed to less than 10% thd (depending on operating pitch)---with none of the problems inherent in solid-state oscillators and sine waveshapers. because the wien bridge contains no piecewise sine shaper or amplitude-control circuit or component. the tube itself performs that job. so the distortion products are entirely low-order, unlike the "sine waves" that solid-state vcos or samplers produce.

turn up the overdrive control, and the oscillator output clips the output amplifier pentode tube, for a unique soft-clipped square-wave sound. the simplicity of the r-54 will fool you--its behavior is odd and radical, and it will take you months or years to fully explore all of its quirks.

now for the special trick. plug an audio signal into the audio input. instantly, the r-54 transforms from a vco into a bandpass resonant voltage-controlled filter, with the same range as in vco operation -- 20 hz to 5 khz. its behavior and sound are unique. again, you will be kept busy for years exploring all of its strangeness.

cv response: hz/v. use a suitable midi/cv interface, or use our r-60 interface to obtain perfect equal-tempered tuning every time. maximum output signal, 12 v p-p power requirement: +-12v dc, 250 ma. (all specifications are approximate and may vary from sample to sample.) tubes used: 19kg8, 6ak5"

Oscillosine - Coming soon from Hollow Sun - Vintage HP Oscillator

"Almost as though it was found in the back of a damp garage after decades of neglect, Hollowsun has created Oscillosine. Reminiscent of an oddball inventor's strange homebrew creation, Oscillosine is designed to conjour the sights, sounds and smells of a 1940s experimenter's laboratory... glowing valves, otherworldly audio and maybe a hint of pipe tobacco.

The samples for Oscillosine are taken from a vintage tube Hewlett Packard sine wave test oscillator estimated to date back to the 50s or 60s, maybe earlier.

The more voices (or notes) the thing tries to play, the circuitry seems to strain slightly and the valves glow brighter which is visible through the front panel aperture.

Oscillosine offers serious abstract synthesis for the adventurous to bring something different to your productions whilst also providing more conventional sounds for more mainstream work.

For safety reasons, be sure to wear a white lab coat when operating Oscillosine."
