4.4OVERVIEW OF THE JUPITER-8VUSER INTERFACE

The interface of the Jupiter-8V has 54 synthesis parameters and a programmer that allows you to navigate quickly through the 44 factory presets of the original machine. The knobs and associated switches to these parameters will allow you to create a nearly infinite variety of sounds.

These parameters consist of:

2 oscillators (VCOs) that deliver the basic audio signal thanks to the waveforms and allow the tuning of the sound (the frequency). VCO1 can produce triangle, saw tooth, variable pulse or square signals while VCO2 can produce sine, saw tooth, variable pulse or noise signals.

A mixer to mix the 2 VCO’s

A non resonant high pass 6 dB/oct filter

A resonant low pass 12/24 dB/oct filter

An LFO

1 amplifier (VCA) allowing amplification of the signal between the filter to the stereo output.

Two envelopes (ADSR) to modulate the low pass filter and the VCA

The synthesis parameters

See how to quickly create a polyphonic sound with the Jupiter-8V:

To be able to understand the principle of how to program the Jupiter-8V, we will take a very simple sound. Select the preset “UJ Brass» in the bank “KUJIIE” / “Brass”. The synthesis structure of this sound is relatively simple: the sawtooth waveforms of VCO 1 are 2 are active and their signals are directed through the low pass filter. Afterwards the signal is routed through the mixer, and finally into the amplifier. An ADSR envelope modulates the cutoff frequency of the filter and a second ADSR envelope modulates the volume of the amplifier.
