Sonically versatile analog filter in a double pack
The CPM DF-8 from Stylophone is a dual analog multimode filter that can be used in stereo or dual mono. The filter box is an ingenious tool for processing drum machines, can give "finished" synth sounds and static samples a new, dynamic character, processes stereo signals and can be used as a backend for the CPM DS-2 to create a complete synthesizer from both devices.
The filter Eldorado
Basically, the compact desktop device consists of four sections comprising Envelopes, Filters 1 and 2 and Main. The two filters have an identical structure. Filter Type allows you to choose from eight different filter characteristics. The GEN R-8 types originate from the in-house synthesizer GEN R-8, each have a slope of 12dB and cover the characteristics lowpass, bandpass, Highpass and notch. Under 2045 there is a 24db lowpass, which has a sound similar to Emulator II (E-Mu, 1984) and three mixes consisting of 12/24dB Bandpass+, Notch+ and Bandstop+. A noise generator can be inserted instead of respectively additive to the input signal. Together with a Lowpass filter, this can be used to create 70s wind and space sounds. In addition to the usual controls for cutoff, resonance and modulation depth, there are Threshold and the trigger behavior for the envelope and switches for filter bypass, VCA on/off, envelope inversion and modulation source.
The envelope section
The section on the left belongs solely to the two envelopes. A switch is used to specify for each envelope whether it should work 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 via the adjustable trigger threshold or the gate input. The voltages of the envelopes are normalized internally to the filters and are also output as a control voltage.
Main Out with mixer, delay effect, S&H & speakers
In the area on the right, you can set the level and or mono or Stereo at which the filters areoutput at the main out. The delay effect is located on the main Out. This is a rather crunchy sounding LoFi delay with a PT2399 chip. S&H aka Sample & Hold is the third modulation source of the CPM DF-8; this function generates random, stepped control voltages. The Sync In socket is very practical, allowing you to synchronize the S&H with a keyboard gate or an external Clock. The many patch sockets invite you to use the CPM DF-8 together with a semi-modular synthesizer, an analogue sequencer or a Eurorack modular system. The filter box can be removed from its housing and installed in a Eurorack housing, where it occupies 42 sub-units and is supplied with power via the system bus. The signal output is via headphones, line output or the internal loudspeaker.
