SYSTEM-500 505 FAQ
  
Q:The openness of VCF 1 does not sound sufficient.
A:
	In consideration of safety, the CV-controllable range for Key Follow is set to be somewhat narrow.
	The FREQ slider is also adjusted so as to match this. This achieves natural filter opening during keyboard performances.
Q:Raising the LEVEL slider makes the sound quality change.
A:
	The characteristics of audible sound are also changed using the LEVEL slider. The level is distorted when the slider is near the topmost area, but this is by intentional design.
Q:Strange sounds are heard when FREQ or RESONANCE is adjusted to certain positions using the VCF 2.
A:
	GAIN is set high with the aim of producing distinctive effects.
	It has intentionally been so adjusted to produce such sounds.
