Je n'ai jamais entendu ou utilisé de VCO pour modulaire qui sonnait fin. (A part certaines wavetables
)
A mon avis, ça n'existe pas. Si tu veux un plus gros son, il faut des formes d'ondes plus riches.
Comme dis Bruce Duncan de Modcan :
In recent years the pursuit of many analogue synth builders has been towards the development of VCOs that achieve accurate pitch tracking, and low drift tuning specifications. This has been seen as the Holy Grail of VCO design in answer to the complaints of users unhappy with drifting pitch especially problematic during live performance. It is now commonplace to have highly stable oscillators with excellent tracking over a wide range.
An unfortunate side effect in this pursuit of perfection is that some users find the results "sterile" sounding and lacking in musicality when compared with early VCO contributions from Moog and EMS etc.
There is nothing inherently "sterile" when comparing a single cycle waveform like a sawtooth from one VCO to the next. A sawtooth is a sawtooth no matter how it is generated. It would require a considerable amount of distortion to the basic ramp shape to change the sound significantly. None of the older VCOs do this in a meaningful way. It is more likely a consequence of subtle tuning errors that creates this perception of warmth in older designs. The "beating" effect of several VCO signals shifting phase against each other can provide a pleasant animation to a patch particularly if concentrated in the bass notes and to a lesser extent in the higher frequencies.
En gros une saw est une saw, sur n'importe quel VCO.
Sinon en cumullant les formes d'ondes de l'AFG, les formes animées et le sub etc... on peux facilement le faire sonner comme 3-4 VCO !
Très très costaud !
Par contre les formes d'ondes animées gagnent à être utilisé avec les SUB.
Perso j'ai remarqué que sur mon systeme, une Saw et une Ramp n'ont pas le même rendu, la ramp ayant un son souvent plus présent, auquel cas il suffit d'inverser la saw pour la mettre en ramp.. Mais cela vient certainement du reste du systeme : Lowpass gate etc... (peut-être à cause du circuit ac-coupled du LPG, je ne sais pas...)
