• Filter ENV controls
An envelope follower tracks the amplitude of the cutoff signal and generates a control signal from
this, which can be shaped by attack/decay controls. In the Filter ENV effects, the control signal
modulates the cutoff frequency of the filter.
Each ENV filter unit features the following controls:
Freq (-48 to 72 semitones)
The cutoff frequency, tuned in semitones relative to A4.
Res (0 to 100%)
The resonance of the filter at the cutoff frequency.
Mode (L6, L12, L18, L24, B12, N12, H6)
MG-Filter:
L1, L2, L3, L4, B2, N2, H1
SV-Filter: L2, L4, H2, H4, B2, B4, N2, N4, P2, P4, A2, A4
Phaser: P2+, P2-, P4+, P4-, P6+, P6-, P8+, P8-
Comb: positive / negative
Attack (1.95 ms to 8 sec)
The attack time of the control signal generated by the envelope follower.
Decay (1.95 ms to 8 sec)
The decay time of the control signal generated by the envelope follower.
Type (RMS, Hilbert RMS, Peak, Hilbert Peak)
The type of peak detection algorithm used in the envelope follower.
Depth (0 to 100%)
The depth to which the resulting control signal modulates the cutoff frequency.
Modtype
(stereo +, linked +, stereo -, linked -, stereo +- linked +-)
This control allows you to choose between several types of stereo modulation.
Bitcrusher LFO and ENV effects
• BIT-CRUSH-LFO
• BIT-CRUSH-ENV
These are similar effects to the bit-crushing units in the Pad effects, although they possess
built-in modulation features. The samplerate frequency can be modulated by an LFO or envelope
follower.
