Multitype Morphing Filter

8 Step Clock

The positive transition (low to high) of a Clock signal

at this input advances to the next step of the current

chain.

If step 32 is reached the next clock switches back to

step 1 of the chain.

If an external Step CV and Step clock signal is

applied the effects of both signals will interfer.

Whenever the step control voltages changes the

step corresponding to this voltage is addressed

immediately !

Therefore we recommend to apply no varying

control voltages to the Step CV inputs in the

clocked mode unless the interfering effects are

intentional.

9 Step Reset

The positive transition (low to high) at this input resets

to the step of the chain that corresponds to the

momentary step CV (manual + external). The manual

step control has to be turned to zero if a reset to step 1

is desired. A slowly varying external control voltage at

the step CV inputs can be used to reset to different

steps.

System A - 100

The step reset input is also helpful to synchronize "filter

sequences" by applying a sequener generated reset

signal to this input (e.g. .

0 Morph

This group of controls serves to define the morphing

time between succeeding filters. It contains a manual

Morphing control and two Morphing CV inputs (one

with attenuator, one without attenuator).

Applying a slowly variable control voltage at one of

the Morphing CV leads to modulations of the morphing

time.

A control voltage of 0V at Morphing CV input 2 corre-

sponds to a few milliseconds (~ switching), +5V to

about 10 seconds morphing time.

The effects of the manual morphing control and the

external morphing CV inputs are added up. The ma-

nual control can be used to adjust an morphing off-

set. The external control voltage (e.g. from a LFO or

sequencer) could modulate the morphing time the

offset. For bipolar control voltages (e.g. from an LFO)

an offset is required to take advantage of the full

voltage range. For positive control voltages (e.g. from

an ADSR, sequencer or MIDI-to-CV) the offset control

may be set to zero.
