Special Hint Ø Filter Gain
If you like distorted or overdriven analog sounds, be sure to experiment with FILTER GAIN.
The filter can be overdriven very effectively, especially in combination with Q/Width.
Sensible programming is required though to avoid unpleasant side-effects.
FltSens = Sets the velocity sensitivity for CUTOFF and Q/WIDTH.
FltScale = Filter Scaling sets the relation between CUTOFF and keyboard position.
A Sample which gets more and more jarring as the pitch increases can be tamed by
combining Filter Scaling and Level Scaling.
EQ = This 1-band EQ does not really belong to the Filter section, since the EQ has an
influence on the Sample independent of the Filter, even if the Filter is set to BYPASS.
Special Hint Ø EQ
The EQ is separately available for each Sample and each Sample Bank. In a drum set for
example you can program a different EQ setting for each single drum instrument. In
multitimbral use the EQ can be set for each Part (= Samples and Sample Banks), which can
normally only be done with professional mixing desks.

F4 = EG
The A3000 uses the classic ADSR envelopes (Attack, Decay, Sustain, Release). For
the Rate parameters, higher values produce a faster envelope transition. In the
default setting all values are set to 127. This means that you must program lower
values for the envelope first to get useful results. This applies mainly for the DECAY
RATE: if in the AEG and with a low SUSTAIN LEVEL the decay rate is set to 127,
only a short click can be heard, as the Decay Rate is extremely short.
AEG = The Amplitude Envelope Generator controls volume change over time by
applying the ADSR envelope.
AEGMode = With RateScl the AEG Rates can be set to change corresponding to the
keyboard position. Vel>Rate makes the AEG Rates depend on the velocity. Attack
Mode changes the function of the ATTACK TIME parameter. The normal setting is
"rate". When set to "hold", ATTACK TIME will no longer determine the rise time;
instead, a HOLD TIME can be set during which the maximum level will be held.
Special Hint Ø Hold Time
Programming a HOLD TIME is recommended for types of Samples in which the sampled
instrument has a characteristic attack phase; e.g. the initial sound of a saxophone.
Without a HOLD TIME, the level would already decay during the initial sound if a
DECAY TIME is set and the sustain level is lower than 127. HOLD TIME is also useful for
Synthesizer sounds if no rise time is required for the sound. The important parameters
FILTER ATTACK RATE and FILTER DECAY RATE can then sound at full level, while AEG
DECAY allows the level to decay little or more later.
FEGRate and FEGLevel = In addition to the ADSR parameters, the Filter envelope
incorporates the LEVEL parameters INIT, ATTACK, and RELEASE. The Filter
envelope is only effective if FILTER TYPE is not set to BYPASS and CUTOFF is set
to a value lower than 127. A setting of zero for an FEG level corresponds to the
specified Cutoff frequency. The FEG Attack Level may be used in the same way as
the FEG DEPTH parameter familiar on other synthesizers. With standard analog
programming the other FEG levels can remain at 0.
