Navi
Parameter Value Explanation
PITCH DRIFT 0–255
Adjusts the slight pitch drift that occurs when notes are played on an analog
synthesizer.
PARAM
EXPANSION
OFF, ON
If this is “ON”, the range of change for LFO RATE, CUTOFF, RESONANCE, and FILTER
ENV DEPTH is wider than on the original model.
CONDITION 0–100 Simulates the changes that occur as a unit ages.
Chord Switch OFF, ON Turns the chord memory function on/off.
Hold Switch OFF, ON
While this is “ON”, the notes you play keep sounding even after you take your
fingers off the keyboard.
Category
Selects the tone’s category.
No Assign–Vocoder (*) The GAIA-2 does not have a built-in vocoder.
MIX MIX
PW LEVEL 0–255 Adjusts the volume of the pulse wave.
SAW LEVEL 0–255 Adjusts the volume of the sawtooth wave.
SUB OSC LEVEL 0–255 Adjusts the volume of the sub oscillator.
SUB OSC
Specifies the SUB OSC type.
1OCT DN
One octave lower
2OCT DN1 Two octaves lower
2OCT DN2 Two octaves lower (small pulse width)
NOISE LEVEL 0–255 Adjusts the noise volume.
LFO LFO
LFO RATE 0–1023 Specifies the speed of the LFO cycle.
LFO
WAVEFORM
TRI, SQR, S&H Selects the waveform of the LFO.
FILTER FILTER
VINTAGE FLT
TYPE
R, M, S
Selects one of three response curves, each modeling the LPF of an analog
synthesizer of the past.
CUTOFF 0–1023
Specifies the cutoff frequency of the low-pass filter. The frequency region above
the cutoff frequency is cut, producing a more mellow tonal character.
RESONANCE 0–1023
Boosts the region of the filter’s cutoff frequency. Higher values produce a
stronger result, giving the sound a distinctively synthesizer-like character.
FLT ENV DEPTH -1023–+1023 Adjusts the amount by which the cutoff frequency is controlled by the envelope.
FILTER MOD 0–100 Adjusts the amount by which the LFO modulates the cutoff frequency.
FLT KEY
FOLLOW
0–200 Varies the filter’s cutoff frequency according to the position of the key.
ENV ENV
ENV MODE
Specifies what causes the envelope to attack.
GATE+TRIG
Attack each time a key is pressed.
GATE Attack when a key is pressed anew. No attack when playing legato.
LFO Attack repeatedly at each cycle of the LFO as long as the key is held.
ENV ATTACK 0–1023 Specifies the ENV Attack time.
ENV DECAY 0–1023 Specifies the ENV Decay time.
ENV SUSTAIN 0–1023 Specifies the ENV Sustain level.
ENV RELEASE 0–1023 Specifies the ENV Release time.
AMP AMP
AMP LEVEL 0–127 Adjusts the volume of the tone.
AMP TONE -63–0–+63 Adjusts the tonal character.
