Hi everybody,

I'd like to suggest a new function, where an increase of the resonance
setting also increases the VCA Level.

Why this?

If you raise the resonance of a filter like in the JX-3P, then the level
of the signal below the cutoff frequency seems to become lower. People
tend so say: "If I increase the resonance, then the sound is loosing bass"
This is not a fault, but technically correct. The overall energy of the
signal is always constant. If you put more energy in the frequencies
around the resonance peak, then you have to take it away at the other
frequencies - which are lower frequencies in a low pass filter.

To avoid this "the sound is loosing bass"-effect some synth
manufacturers implemented in their synth simply dual potentiometers for
the resonance: One half controls the resonance, the other half of the
potentiometer adds signal level to the VCA, when the resonance is
increased. Most well known examples are the Roland TB303 and the Roland
System 100.

I'd like to have this for the JX-3P also. In fact I want that the
effective control voltage for the VCA is reduced to 66% if resonance is
at minimum and provided with 100% if the resonance is at maximum.
Of course this would not be necessary if you only think of static
settings in various tones. But I use the resonance control in realtime
for climaxes, and controlling both parameters coordinated at the same
time in a live situation is an overkill (not to speak, that I usually
need one hand for playing the keyboard ;-) ).

So, what do you think about this "System 100"-like behaviour?
