Oscillator mix

Osc Mix

Oscillator Mix sets the balance in amplitude be-
tween oscillator 1 and oscillator 2 .
Amp & Filter Envelopes
The Amp and Filter envelopes are used to control how the sound
changes over time . By modulating the amplifier and/or the filter with an
envelope, the sound can be given its basic "shape" and evolving tone
character . In fact, the "volume shape" is one of the most important
factors to how we identify the sound . By setting up a proper amplifier
envelope you can make a sound "soft", "hard", "plucked" "static" etc .

Attack

Amp & filter envelopes 2
amount
attack (time)
key down
Attack is the time it will take for the envelope to go from zero to the
maximum amplitude as soon as a key have been pressed .
Range: 0.5 ms to 45 s
A very short attack time could produce a click in the beginning of
the sound. To eliminate this, increase the attack time slightly.

Decay

amount
attack (time) decay (time)
key down
Decay is the time it takes for the envelope to drop down to the sustain
level after the attack phase has been completed .
Range: 0.5 ms to 45 s
If Sustain is set to the maximum level, a Decay time will have no
effect since the envelope "is already" at the Sustain level.
