Okay, okay, but next time, learn french, doh
Virus KC Tuto :
Reproduction of the sequence of Chants Magnétiques Part 1 :
Excerpt :
Original Sequence
Introduction :
You need to keep in mind that the perfect reproduction doesn't exist, each instrument has its own tune and its own sound touch almost given thanks to the filter, the stability of the VCOs and the quality of envelopes.
So, same parameters between two different synths won't give (for most of them) same results.
It's really impossible to have the same heat of the sound of an ARP 2600 with a Virus KC for example.
Midi Sequence :
MIDI Sequence
Description of the patch :
VCO-1 :
Wave almost square
(still remains a bit of triangular component)
DEMO VCO1
VCO-2 :
Triangular wave (TRI)
Detune : 50%
Semie Tone : one octave up
SYNC : ON
(VCO-2 is synchronised on the period of the first)
DEMO VCO2
DEMO VCO1 and VCO2
(rem : you need to bring the VCO1 out in the parameters of the balance)
VCO-3 :
Slave of VCO-2 (as VCO-2 = triangular)
Permits to make the sound fatter and richer.
DEMO VCO1, VCO2 and VCO3
(The add of VCO3 is a real must, you make the harmonics warmer, the sound becomes interessant)
AMP Enveloppe :
Attack:9;Decay:61;Sustain:71;Release:0
(min value : 0 ; max value : 127)
Filter Enveloppe :
Attack:10;Decay:40;Sustain:0;Release:127
(min value : 0 ; max value : 127)
Filter LP :
Enveloppe Amount : 61%
Cut-Off : 39%
Modulation Matrix :
KeyFollow of 9% modulates the Cut-Off
The KeyFollow is a value changing in a linear way from the low to the high of the keyboard.
We want here with a Cut-Off to have a lightness of the sound more elevated in the high part of the keyboard.
This result in brighter notes in the high part of the keyboard and more muffled in the low part.
Mod Wheel of 10% modulates the Cut-Off
Could have been any other controller, here we can change the value of the Cut-Off with the modulation wheel, on the midi given in this post, the values of the wheel are different for each note. The sequence is richer and it has a huge influence on the quality of the echoes.
We limit a lot the unpleasant effects of recovering of identical notes.
JM Jarre metuculously choosed the values of Cut-Off in fonction of the echo for the whole thing to make a global sounding thing and not a sequence and echoes we could distinguish too much.
Other :
The legato is activated, if two notes are recovered, the envelope of the second note is not activated again (as the Minimoog).
Result :
Dry sequence
Sequence with echo (4)
I may have done some mistakes, if you don't clearly understand one part, just ask me to translate it again with other words
Just buy yourself osciloscope
