SMS to Serge Converter Panel

"very rare Serge to SMS converter panel. What this panel does is convert Serge Modular CV signals to Salamander Modular Synth signals. At its core, this module is a banana jack to 1/8" jack converter, however it is an active module and also provides for voltage attenuation via two switches. For every input, there are two outputs and the module contains two discrete sections: one specifically for going from banana to 1/8" and one for going from 1/8" to banana connectors."


Buchla Original Quad Voltage-Controlled Envelope Generator Model 284

"Rare Buchla Original Frequency Quad Voltage-Controlled Envelope Generator Model 284.
Historical Vintage Series 200 Synth System.

Dimensions approx. 8.5" x 7" x 3"

Adds voltage control and variable delay and duration times to the capabilities of the Model 280 (Four independent envelope generators with variable attack and decay times (range is .001 to 10 seconds) and a choice of sustained or transient operation. Input pulses initiate envelopes and optionally control duration time; output pulses, activated at end of decay, are particularly useful for advancing sequencers or looping to inputs to generate repetitive functions.).
All times are internally variable from .002 to 10 seconds; control voltages may be used to extend this range and control overall time while preserving envelope shape. http://www.buchla.com/historical/b200/284-vcenvgenerator.html"

"Rare Buchla Original Frequency Quad Spatial Director Model 204.
Historical Vintage Series 200 Synth System.

Dimensions approx. 8.5" x 7" x 3"

Voltage controlled quadraphonic distributor for determining the spatial location of sounds with pan pots or externally applied voltages. Monitor switches and voltage controlled attenuators are included.

The 204s features include:

4 electronically isolated 2-dimensional joysticks with output voltages proportional to lateral and vertical displacement. Generally used to control sound location, but may be used to control other parameters.

4 gain controls for signals applied to inputs. Control voltages may alternatively be used to control amplitude.

Control voltage inputs for defining positions of sounds. Increasing voltages move sounds from rear to front and from left to right. Voltages are generally (but not necessarily) derived from adjacent joystick outputs.

Monitor switches for use in conjunction with the Model 226 Quad Monitor Interface.

"Rare Buchla Original Frequency Shifter/Balanced Modulator Model 285.
Historical Vintage Series 200 Synth System.

Dimensions approx. 7" x 4" x 3"

Shifts frequencies contained in input signal by an amount equal to externally applied or internally generated reference frequency. Internal reference generator is voltage-controlled, frequency-modulated, and provides the capability of continuous shifting through zero. Raised and lowered frequencies are simultaneously available. Unit incorporates a separate, voltage-controlled, balanced modulator, providing continuous transition from unmodified to amplitude-modulated and ring-modulated signals."

"Rare Buchla Original Dual Oscillator Model 258.
Historical Vintage Series 200 Synth System.

Dimensions approx. 7.5" x 4" x 3"

Two independent voltage-controlled oscillators, continuously tunable from 5 Hz to 20 kHz. Each has two processing inputs and a frequency modulation input. Waveshapes as well as frequency can be voltage controlled. Model 258 oscillators feature low sine wave harmonic content, negligible settling error, and high short and long-term stability, even with rapidly changing ambient temperatures.

Controls and I/O

Processing inputs
Two processing control inputs permit multiple control of pitch without need of separate external processor.
Processing controls
Used to set desired range of frequency control. Expansion, compression, and inversion of scales are accomplished here.
Frequency modulation control
For adjusting vibrato depth or creating clangorous or bell-like tones, rich in non-harmonic partials.
Output
Signal amplitude is +4 dB. Output impedance is 600 ohms.
Oscillator frequency control
Spans the audio spectrum of 5 Hz to 20 kHz with no range switching. (Applied control voltages can extend limits to .1 Hz and 30 kHz.)
Waveshape control input
Waveshapes can be varied from sine to saw (osc 1) and sine to square (osc 2). Voltage control of waveshape enables powerful dynamic control of timbre."
