The FM Aid module makes it possible to produce the great and very deep sounding linear Thru-Zero frequency modulation with any VCO. The module works with arbitrary signals as carrier and modulator. The module copies FM in how it is done in digital implementation, but in a completely analog circuit free of digital aliasing artifacts.

The Super Sawtor produces a unisono effect with plenty of harmonic content from the incoming waveform. It adds a number of detuned harmonics to the original signal and sounds like Roland's supersaw from the JP-8000.

MMM VCF stands for M°°g Multi Mode Voltage Controlled Filter and is a dual filter featuring common controls for both filters. For that reason it can be used as a stereo filter but you might as well use it in different filter type combinations as it features individual low pass, band pass and high pass outputs for each filter.

In only six HP Happy Nerding's 3 x MIA module unites three mixers, inverters and attenuator channels, using dual contrentic polarizer controls. Each group of two inputs can generate offset voltages, can be utilized as a 2:1 mixer or as an polarizer for scaling signals. Switches sum the groups's outputs and expand the mixing functionality by different mix configurations.

The 3x VCA comprises three high-class amplifier circuits, which can be used with audio and CV signals. Thanks to its dual potentiometers, the module is very slim. However, in terms of functionality, the 3x VCA leaves nothing to be desired. Each channel comes with level control, a control voltage input plus bipolar attenuator, routing functions and LEDs to visualize input and output signals.

PanMix is a compact stereo mixer featuring six input channels. Volume and panorama position of incoming signals can be adjusted via dual concentric knobs. Furthermore, there is a routable CV input plus attenuator / inverter per channel. The stereo master section comes equipped with LED level meters and another volume control. Besides L/R outputs, the module offers a headphone jack. High-grade components guarantee clean, distortion-free sound.

The HN VCF is a multifaceted state variable filter with drive section. The circuit offers a high-pass, a band-pass and two low-pass outputs with varying slopes and distortion ranges. In result, the module can be used for smooth as well as aggressive sound processing. Thanks to its concentric potentiometers, the HN VCF takes up very little space in a modular system.

Good-natured equalizer with beefy overdrive – The TriTone comes equipped with three semi parametric bands, which work with shelfing respectively bell characteristic. Frequency and control ranges are wide enough to not only allow small adjustments but creative sound design as well. CV inputs plus bipolar attenuators enable the user to modulate the application point of each band. Hi levels result in strong saturation effects. Thanks to separate inputs and outputs, it is not only possible to use the bands in conjunction, but individually as well. In terms of sound, the TriTone shines with a gentle character. – At least as long as the signals fed to the module are rather low. High values lead to fierce, yet musical distortion.
