EVERYTHING SYNTH




Previous Roland drum machines had offered only a selection of preset rhythms. The CR-78's key new feature was that in addition to offering 34 preset rhythms, it provided four programmable memory locations for storing patterns created by the user. These could be created by using step programming with the WS-1 box, which was available as an optional extra. [4]

Voltage: Two voltage outputs are available and separately adjustable, but both are subject to the same time control — i.e. the steps of the staircase occur at the same time from both outputs. At zero, there is no voltage variance at all, and as the setting is increased the variance about the mean voltage (set at the device being controlled) becomes greater, excursions being both positive and negative of the mean voltage. In addition, a trigger pulse is sent whenever a random selection is made, and a lamp on the panel glows at the same time.

"Out of nothing more then curiosity i wanted to know the fundamental differences between the Moog Voyager & Minimonsta. The filter is obvious so i didn’t even want to have that in the equation. I wanted to look at the raw building blocks, the oscillator waveforms. Here are my results."

The sound then travels from the VCO to the VCF (voltage-controlled filter) where it can be shaped and sculpted, adding resonance. Next, the sound travels to the voltage-controlled amplifer (VCA). The term "amplifier" can be a bit misleading to novices who might be thinking of a stereo amplifier with a single volume knob. In a modern synthesizer, a VCA actually has 4 separate volume knobs that control four different stages of the sound. For example, the first knob - the Attack volume - controls how loud a sound is when the key is first pressed: does it start immediately like a string being plucked? Or does it fade in gradually like a violin being softly bowed?

Amazing Sounds and Expression Possibilities
Roland V-Synth GT at a Glance:
"The Roland Jupiter 6 was release in 1983 at a list price of $3,000, measuring 42" wide, 4 ¾" high, and 17" deep. It tips the scales at 35 lbs. The Jupiter 6 ("J6") is a 6 voice synth with a splittable keyboard, memory for 48 tones and 32 patches (two tones set up in a split combination). Each voice consists of two voltage controlled oscillators, a multi mode filter, two ADSR envelopes, and LFO. The unit has a second LFO which is shared by all six voices. Oddly enough while the unit can do splits it does not have a dual mode (due to the way the voices are split up). There are two separate synthesizer boards found in side the board a two voice unit and a four voice unit which are under separate control and allows for the splits..."
