The Module Expansion Bus allows to connect several, additional control modules on the M800- Synthesizer Main Module. This enables a quick overview and real time change of the parameters to the synth-engine. In this case the M808 represents a multimode filter section.
It is possible to just use one module to change parameters for different instances of oscillators. To select the specific instance use the “Assign Button”.  In addition, for every instance you are able to use your own module.

The haptical feeling of the precise encoder with a LED ring gives you maximum control even for live setups.
The storing & retrieving of the parameters save your work.

RESO:              Value (0 to 100%) feedback amount (Resonance)

<MODE>:         LP = Lowpass, BP = Bandpass, HP = Highpass, NS= Notch.   

CUTOFF:          Value (60 to 17400 HZ) Cutoff frequency in herz (encoder input expontial) 

ENV-AMT:       Value  (0 to 100%) amount of ENVELOPE control signals to shift the filter cutoff frequency

<TYPE>:           BYPASS:

                          LP24: Lowpass filter (Biqaud) 24db

                          DIODE_LD12:   Diode ladder filter (Steiner Parker) 12db

                          MOOG_VCF: multimode classic state variable filter 12db

                          SEM:  multimode state variable filter (Curtis chip emulation)            

INPUT:              Value  (0 to 100%) input signal level

                          OFF kein keyboard track

                          3:1  30% keyboard track

                                                                                   2:1  60% keyboard track

                                                                                   1:1  100% keyboard track

Function on the M800:

Multimode Filter

This module controls the function of the analog filter which emulates several classic analog filters (FILTER) on the M800. The values are reflected in both directions even when you change the parameter on the M800 or on the M808 module.
