Overview of the Jupiter-8V user 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 (VCO) deliver the basic audio signal thanks to the waveforms (triangle, saw
tooth, square and triangle) and allow the tuning of the sound (the frequency).
•
A mixer to mix the 2 VCO’s
•
A non resonant high pass filter 6 dB/oct
•
A resonant low pass filter 24 dB/oct
•
An LFO
•
1 amplifier (VCA) Allowing to amplify the signal going out of the filter to direct it toward 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 “1_Osc" in the bank "Templates". The synthesis structure of this
sound is comparatively simple: the saw tooth wave form of VCO 1 is active and the signal is directed
through the low pass filter. Afterwards it is routed through the mixer, and finally into the amplifier.
An ADSR envelope modulates the cutoff frequency of the filter and a second ADSR envelop
modulates the volume of the amplifier.
