Envelopes Extras
VEL > FM
Controls the amount velocity will affect the output level of the FM envelope. At a setting of
zero, there will be no effect - it won’t matter how hard or soft you play the keyboard, there will be
no difference in the sound. At values between 1 and +63, the harder you hit the keyboard, the
brighter the sound will become. At values between -1 and -64, the harder you hit the keyboard,
the softer the sound will become.
Note : For this control to have any effect at all, the FM LEVEL knob (discussed on Page 56)
has to be set to a value other than zero. If FM LEVEL is set to zero, the VEL > FM control has
no effect.
VEL > AMP
Controls the amount velocity will affect the overall output level of the selected sound. At a
setting of zero, there will be no effect - it won’t matter how hard or soft you play the keyboard,
there will be no difference in the sound. At values between 1 and +63, the harder you hit the
keyboard, the louder the sound will become. At values between -1 and -64, the harder you hit
the keyboard, the quieter the sound will become.
VEL > MOD
Controls the amount velocity will affect the overall output level of the MOD ENV. At a setting of
zero, there will be no effect - it won’t matter how hard or soft you play the keyboard, there will be
no difference in the sound.
The effect other settings will have on the sound depends very much on where the MOD ENV
is routed.
If the MOD ENV is controlling the filter’s cutoff frequency, at values between 1 and +63, the
harder you hit the keyboard, the brighter the sound will become. At values between -1 and -64,
the harder you hit the keyboard, the softer the sound will become.
Note: With positive values set for this control, if the filter cutoff frequency is set quite high, you
may not notice much difference in the sound even when extreme velocity is used. In this case,
you should reduce the filter’s cutoff frequency slightly until the desired result is achieved.
If the MOD ENV is controlling oscillator pitch, at values between 1 and +63, the harder you hit
the keyboard, the pitch sweep will be greater (higher). At values between -1 and -64, the
harder you hit the keyboard, the pitch sweep will be less.
If the MOD ENV is controlling pulse width at values between 1 and +63, the harder you hit the
keyboard, the more the pulse width will be affected. At values between -1 and -64, the harder
you hit the keyboard, the less the pulse width will be affected.
ENV TRIGGER
These functions only apply to a sound which has been set up to behave in a monophonic
manner (see Voice Mode on Page 60).
When the Voice Mode is set to any of the Mono options, different envelope triggering options
are available for legato playing styles (notes overlapping).
When the first note of a musical phrase is played, it might be desirable to have both the Amp
and Mod envelopes trigger. For the remaining legato notes, just the Mod envelope re-
triggering would create the effect of the phrase becoming quieter and quieter.
When these are set to SINGLE, the appropriate envelope will only be triggered when the first
keyboard note is played. Any subsequent legato style key presses (i.e. playing another note
whilst holding down the first note pressed) will not re-trigger the attack/decay stages of
envelope. Single triggering is useful when emulating certain solo instruments such as
woodwind - it is also good for emulating older analogue synths such as the MiniMoog that had
single triggering.
