Information

A full specification Keyboard synthesiser with the facility of instant push button patching - Temperature compensated oscillators with vernier tuning: - Two envelope shapers for extra effects - Stereo output with panning controls - External inputs, such as voice or instrument, can be processed INSTRUMENT DESCRIPTION The Minisonic II is a three octave Keyboard synthesiser featuring push-button patching of audio signal and control voltage options. Two temperature compensated log law v.c.o.s of greatly improved design offer, in addition, facilities for cross modulation and phase locking up to the ninth harmonic. These latter features considerably extend the range of sounds of which the instrument is capable and it is particularly easy to create close imitations of a number of reed or woodwind instruments. Two envelope shapers and voltage controlled amplifiers are incorporated with the envelope from channel 1, being made available in its normal and inverted form as a modulation source. The envelope state from each device is monitored by a light emitting diode which varies in brightness with the envelope level. The Keyboard Controller is similar in form to that which appeared in the original Minisonic but offers a number of improvements. Like the original it is possible to adjust the register and span of the Keyboard but, in the case of the Minisonic II, provision has been made for balancing the gain of the operational amplifiers in the Controller so that interaction between tune and span controls can be eliminated. Additionally, an equal temperament span is available at the touch of a button. The hold circuit, or pitch memory, of the Controller has been provided with a variable “Portamento” control so that glide effects of up to one second duration may be achieved. In addition an isolator has been incorporated to reduce drain on the hold capacitor thereby ensuring that an unvarying pitch may be maintained for periods up to 40 seconds. A voltage controlled low-pass filter having a passband variable in the range 3Hz-15kHz is incorporated. % V.C.F. can provide a vast range of sounds % Integral three octave Keyboard % 23 push button patching system
