Here's what KMA say about the HorizonT:
The Horizont’s mission is to push way beyond the classic phasing sounds of yesteryear, and take you to uncharted phaser worlds the second you plug in. By combining lush analog JFET phasing with digitally controlled dynamics, Horizont creates a vivid and expressive modulation experience, all while providing experimental and creative features that’ll kick phasing well into the 21st century.
Besides the more common phaser controls, the Horizont offers a plethora of new and exciting options for all the interstellar tone chasers out there. To greatly broaden the range of phasing tones available, we implemented a digital LFO with no less than eight different waveforms: Ramp Up/Down, Sine/Triangle/Square wave, a sweeping waveform, Sample & Hold and a random slope waveform going from 20s down to 40ms.
The implemented envelope generator is one of Horizont's absolute key features. It transforms your input signal into a control source to modulate the speed of the digitally controlled LFO or lets you manually phase for a resonant touch wah-like sound, depending on the state of the SWP- and SPURTCONTROL-Switch.
Set the SPURTCONTROL switch to LFO to let the SPURT knob adjust the internal phasing speed. However, by flicking the switch to ENV (Envelope) mode, it allows you to dynamically modulate the speed along the full LFO speed range, based on how loud the input source is (e.g. when you attack the strings hard). You can also combine the SPURT knob and the envelope by flicking the toggle to LFO+ENV where SPURT then sets the minimum speed. For even more control, you can even plug in an external expression pedal/CV-source (0-5V) to alter the minimum speed on-the-fly or you can use the TAP TEMPO switch (tap just twice) to set the speed to fit in with the tempo of your music.
The EXP-Mode switch also lets you choose between a manual phasing mode, controlled by an expression-pedal or an external CV source. Setting the EXP-Mode switch to the middle position will disable any external expression control. The SWP (Sweep) switch lets you decide to use either the LFO or the envelope of your instrument signal to control the phasing.
In order for you to levitate through spacetime, we’ve also added a stereo output to the Horizont. You can switch between a standard stereo output or a panning output, via the STEREOPAN switch. Synchronized with the LFO speed, the upper cycle of the LFO sends the signal to the OUT1 and the bottom cycle to the OUT2. This is without a shadow of a doubt the most liquid and astonishing phasing experience you’ll ever embark upon. But wait, there’s more! Stop and take a deep breath, set the MIX control to fully clean and the Horizont is transformed into a Tremolo on-the-spot, with all the other aforementioned features.
Last but by no means least, we equipped the Horizont with an FX-Loop right in front of the phase-shifting line. This enables you to add your own secret sonic weapons to this spaceship, seeing you create your very own unique phasing sounds. We’ve also increased the pedal’s headroom drastically by boosting the internal circuit voltage to 18V, from the regular 9V input, to give the cleanest phasing possible no matter what instrument or line source you use.
