Filter Box
The FILTER BOX receives its signal from the HARMONIC COMBE FILTER and is used to change the mono signal produced by the OBJECT GENERATOR into a stereo signal, and set the overall frequency range and gain of MoGi before further modification to the stereo image is applied using the post effects.

It does this by sending the mono signal through two filters, one high pass and one low pass, the ratio of low to high is adjusted with the EXCHANGE dial, as you move the dial from the left to right the cutoff point of the two filters will move upwards.

Think of it as a keyboard with a split point, as you move the dial the split point will move up and down the keys, the lower part is the low pass filter and the upper part is the high pass filter, and the split point is where the two filters crossover. (same as a crossover in a two way loudspeaker)

The two filtered mono signals then enter a stereo mixer with pan, by adjusting the FILTER LP-HP dial you can alter the placement of the high and low frequencies of the signal.

By using this combination of filtering and panning the two dials will give a pseudo stereo image based on the scale of the instrument.

The stereo signal is then passed on to the OCTIVE FILTER BANK via a fixed limiter (the limiter is always on).
Octave Filter Bank
The OCTAVE FILTER BANK receives its signal from the FILTER BOX via a fixed limiter (the limiter is always on).

The DISPLACE switch disconnects the filters from the MODUS ACTIVITY turning them into eight variable bandpass kill filters (all dials down no signal will get through), it can be bypassed with the small FB ON switch.

The 8 stereo filters are made up from 32 single pole high pass and low pass filters, the filters are combined to produce 16 band pass filters, the band pass filters are equally spaced from low to high spanning eight octaves, the position that each filter sits in the spectrum is set by the DISPLACE dial (above the switch), when DISPLACE is on the filters will move up and down the spectrum and across the stereo field following the MODUS ACTIVITY.

The signal is then passed on to the STEREO MOTION processor.
Stereo Motion
The STEREO MOTION effect receives its signal from the OCTIVE FILTER BANK, it can be bypassed with the small SM ON switch.

The top dials process the left signal and the bottom dials process the right signal received from the filter bank.

This is the second stage in the post signal chain and useful for adjusting the overall balance and movement of the stereo image before entering the time based effects.

MOTION will only have an effect if the BORDER dials are above zero.

MOVEMENT adjusts the speed of the panner and BORDER effects the width of the stereo environment.

INFLUENCE and EQUALITY alter the phase path of the Panner.

PLACEMENT is used to position the left and right inputs anywhere along the main left and right output paths.

The MASTER outputs are used to set the balance and feel of the stereo image.

The signal is then passed onto the BOUNCE DELAY effect.
Bounce Delay
The BOUNCE DELAY receives its signal from the STEREO MOTION effect, it can be bypassed with the BD-ON switch.

The flanger section of the delay is influenced from MODUS ACTIVITY, by adjusting the FLANGER and the RATE dials you can alter the amount of flanger effect present in the delay signal.

DEPTH, REGEN and DAMPEN effect the sound of the flanger and the BALANCE dial crossfades between the flanger and the delay.

The DELAY time can be adjusted from 0.001ms to 1,500ms for fine adjustment hold down the shift key, selecting the SL switch increases the delay time by a factor of 4, this gives the delay a maximin of 6000ms.

REGEN, BOUNCE, FLOOR and DAMPEN effect the sound and placement of the echoes, the EFFECT dial crossfades between no effect and effect only.

The signal is then passed onto the ATMOS SPACE effect if the parallel switch is set to off.

The PARALLEL switch is used to to change how the two effects are connected to each other, when off the output of the Bounce Delay is connected directly to the input of the Atmos Space, the two effects run in series, when switched on both effects receive their input from the Stereo Motion, both of the effects are then combined before being passed onto the Dynamic processor.
Atmos Space
The ATMOS SPACE receives its signal from the BOUNCE DELAY effect, unless the parallel switch is on then it receives it's signal from the Stereo Motion, it can be bypassed with the AS-ON switch.

The first process is the pre DELAY, this allows a small amount of space to be place to the front end of the ROOM, the pre delay is stereo and the left and right delay times can be offset with the EQUALITY dial adding a shift to the image.

Next are the three stereo equalisers, the equalisers are wired in parallel, the first is a 1 pole LOW shelf filter, the second is a 2 pole parametric MID and the third is a 1 pole HIGH shelf filter, each of the eq's can be set to cut or boost the signal.

The signal then enters the ROOM, this sets the overall size of the space, at the lowest settings and with careful adjustment of the equalisers and filters you can effectively reproduce the body of an instrument, as you move this dial to the right the reflections will become more spaced producing a larger ambience, to tame the room's reflections the DAMPEN dial is used to reduce the high frequencies, to limit the amount of boom that is present adjust the FLOOR dial to the right.

The signal is then passed onto an output limiter (the limiter is always on) and then last in the chain is the DYNAMICS processor.
Dynamics
The Dynamics processor is last in the signal chain.

The INPUT dial sets the compression threshold.

The OUT dial sets the Master Output Gain.

RATIO adjusts the amount of compression being applied to the signal.

The SHAPE dial is used to control how fast and the amount of time the compression takes effect.
