The filter Eldorado

Basically, the compact desktop device consists of four sections comprising Envelopes, Filters 1 and 2 and Main. The two filters share an identical structure. Filter Type lets you choose from eight different filter characteristics. The GEN R-8 types are derived from the in house synthesizer GEN R-8, each featuring a 12dB slope and covering lowpass, bandpass, highpass and notch characteristics. Under 2045 you will find a 24dB lowpass with a sound reminiscent of the Emulator II E Mu 1984, as well as three mixed modes consisting of 12 24dB Bandpass+, Notch+ and Bandstop+. A noise generator can be inserted instead of or in addition to the input signal. In combination with a lowpass filter, this allows the creation of classic 70s wind and space sounds. In addition to the standard controls for cutoff, resonance and modulation depth, there are threshold and trigger behavior controls for the envelope, as well as switches for filter bypass, VCA on off, envelope inversion and modulation source.

The envelope section

The section on the left is dedicated entirely to the two envelopes. A switch determines for each envelope whether it operates as a classic ADSR or as a looped AR envelope. The curve characteristics can also be switched between linear and exponential. The envelopes are triggered either via the adjustable trigger threshold or via the gate input. The envelope voltages are internally normalized to the filters and are also available as control voltage outputs.
