ADSR
Crumar Bassman has 2 envelope generators:
ADSR1
for
VCF
e
ADSR2
for
VCA
,
they offer 4 parameters:
“ATTACK” , “DECAY” , “SUSTAIN” , “RELEASE” : release doesn’t have an
indipendent control, it is fixed or it follows “DECAY”: For change the behaviour
operate in this way:
Press and hold “RECORD” , the press “WAVEFORM” in
OSC2
section
;
you have
4 options:
0 = fixed release
1 = release = decay for ADSR1
2 = release = decay for ADSR2
3 = release = decay for ADSR1 & ADSR2
MODULATION – LFO
“
MODULATOR
” section or LFO (Low Frequency Oscillator ) of Bassman allows
modulation of suond with waveform of sawtooth, triangular or square.
4 associated controls: “GLIDE”, “RATE”, “WAVEFORM” e “DEPTH”.
“GLIDE” activates the Portamento function, a light “transportation” from one note
to another; the button regulates time of transportation with 4 defined periods.
Control leds will light with every pression of button.
a) no portamento – lo led light
b) ¼ - first led
c) ½ - second led
d) 1/1 – third led
“RATE” sets the oscillation speed between 10 sec & 100Hz.
“WAVEFORM button in “MODULATOR” section acts for select the waveform type
for the modulation: 4 selections controlled by the control leds.
e) Triangular – led 1
f) sawtooth – led 2
g) Square – led 3
h) Sawtooth - One Shot Mode ( the three leds will light ) – in this case the
modulation is not ciclic but it passes thru the waveform only one time.
“DEPTH” sets the modulation target and intensity. Turn from center to left you
can modulate the oscillator by pitch ( or pulse width) with increasing intensity,
turn from center to right, you can modulate the cutoff filter.
In center position the modulation is OFF.
