Installation
Before you start Morphor modules are designed to be used with an Eurorack-compatible case and power supply. We recommend you to use a case with an adequate high-quality power supply. Before installing the module in your case, you must ensure your power supply has a free Eurorack standard PSU connector (2×8 pin header connector) and sufficient available capacity to power the module:
1. Make a separate sum of the +12 V, -12 V and +5 V maximum current draws respectively for all your modules, including the new one. The maximum current draw is specified in the manufacturer’s technical specifications for each module. You can use a tool like ModularGrid to help you calculate the total values for your case.
2. Compare each of these sums to the specifications of your case’s power supply.
3. Proceed only with the installation if none of the total values exceeds the power supply’s specifications. Otherwise you must remove some modules to free up some capacity or upgrade your power supply to allow more capacity in your case. If you do not adequately power your modules, it may result in damage to your modules or power supply. If you are unsure, please contact us before proceeding.
4. Make sure your case has enough free space (HP) to fit the new module. To prevent screws or other debris from falling into the case and shorting any electrical contacts, do not leave gaps between adjacent modules, and cover all unused areas with blank panels. Similarly, do not use open frames or any other enclosure that exposes the backside of any module or the power distribution board.

Installing your module
Always turn off the power to the case and disconnect the power cable when installing or removing a module from your case to avoid injury or equipment damage.
The Morphor Multimode VCF uses the -12 V and the +12 V rail of the power supply (using a standard Eurorack 2×8 pin connector). The red stripe of the included ribbon cable (-12 V side) must be oriented on the same side as the “RED -12 V” marking on the module and on your Eurorack power distribution board.
The module draws a maximum current of 35 mA from the +12 V rail and maximum 50 mA from the -12 V rail.

Introduction
The Morphor Multimode VCF is an intuitive but feature-packed 8HP analogue filter module. Featuring a dedicated lowpass and highpass filter core, this module offers a lot of flexibility to create unique filter characteristics. To shape the sound exactly the way you want, both filter sections have cutoff control over the whole audible frequency range through a knob and bipolar CV jack. Additionally, resonance control and a switchable pole selection are available to offer a wide range of options. The second output acts as both a Bandpass and Highpass output, depending on the position of the BP/HP mixing knob. Combining all these features results in an easy-to-use but flexible module for all your filtering needs.
Happy morphing!

Controls & Connections

INPUT [ 1 ] Insert your audio signal in this protected input.

CUTOFF [ 2 ]

Set the cutoff frequency of the Lowpass or Highpass filter with

these controls. The cutoff can sweep through the whole audible

frequency range to get complete control over your sound.

CUTOFF CV [ 3 ] Bipolar CV jack to add extra cutoff frequency modulation.

RESONANCE [ 4 ]

Set the amount of resonance of each filter section with these

separate controls. Add enough resonance to make the module

self-oscillate. Dual sine VCO for free!

SLOPE SELECTION [ 5 ] Create unique and interesting bandpass filters with the flip of a

switch! You can change the slope of both filters separately with

these toggles.

BP/HP MIX [ 6 ]

By turning this control you can change how much Lowpass

filtering happens on the BP/HP output. Go for a strong bandpass,

a clean highpass, or something in between.

OUTPUT [ 7 ]

Your uniquely shaped analogue audio output.
