Filter
Argon8 has 4 state variable 2-pole resonant filters to choose from: Standard, Standard Notch,
Classic and Classic Notch (all capable of morphing from low pass, through band pass / notch,
to high pass).
• Cutoff: This parameter controls the low-pass filter cutoff frequency. This affects the
cutoff frequency of the filter, from 0Hz up to 22kHz.
• Reso: This parameter controls the amount of resonance of the filter.
• Morph: This encoder allows control of the shape of the filter: note that the filter is low-
pass by default.
- At it’s minimum value you have a low pass filter;
- We move through a sort of low-shelving;
- At It’s midpoint we have a band-pass filter or notch filter;
- At it’s maximum value a high-pass filter.
TIP: With this feature at lower settings you can dampen the low frequencies while
maintaining a rich high-end texture.
• Type: This parameter selects the current mode of the filter. The filter types available are:
- Standard
- Standard Notch
- Classic
- Classic Notch
Envelopes
Argon8 provides 3 separate 4-stage Envelope Generators (i.e. envelopes), one for the filter
(FILT-EG), one for the amplifier (AMP-EG) and one for modulations (MOD-EG). With negative
amounts only the attack, decay and sustain levels are inverted, the release phase will still tend
to 0.
The envelope generator represented on the encoders can be selected using the 3 dedicated
buttons to the right of the envelope depth encoder.
• Attack: This parameter controls the time passing from the moment you press a key (i.e.
‘MIDI Note On’ message) until the sound reaches its maximum value.
• Decay: This parameter controls the time passing for the envelope to drop from its
maximum value to a sustain level (see below).
• Sustain: This parameter controls the level of the sustain phase (i.e. the volume of the
sound while keeping the key pressed for AMP-EG). If there are no modulations active, this
volume keeps constant until you release the key. (The envelope then enters the ‘release’
phase)
• Release: This parameter controls the time passing from the moment you leave a key (i.e.
‘MIDI Note Off’ message) until the sound reaches silence.
• Depth: This controls the envelope depth amount of the selected envelope generator (i.e.
FILT-EG, AMP-EG or MOD-EG.) This gives bi-polar control of the amount of modulation
the envelope has over it’s destination/s.
• FILT-EG, AMP-EG, MOD-EG: These buttons selects which envelope generator the above
controls are representing.
Pressing the MOD-EG button again latches the assign mode - you will notice the LED
blinking to indicate you are in assign mode. Press again to exit assign mode.
TIP: Holding down any of the EG select button and changing the ADSR parameters will
alter all three envelopes simultaneously and is a useful shortcut to quickly change all
envelopes at once.
