KMA Audio Machines

Notes: The first outing for KMA's unique and custom AI driven True Double Tracker technology was in the ENDGAME, their powerhouse end-of-chain pedal. KMA designed their dead-simple-to-use, TDT Algorithm in ENDGAME to be as authentic to the doubling recording process as possible, but they realise that not everybody needs all the bells and whistles of such an all-encompassing device.

However, the processing power requirements required for TDT meant a simpler device wasn't yet possible. But as demand from the community grew, KMA's team worked hard to squeeze it down and make it happen.

So, meet GEMINUS - all of KMA's True Double Tracker goodness in a compact pedal that's suitable for any board. Whether playing live or recording with a single instrument, GEMINUS is the perfect solution for adding "fatness" and "width" to your performances - it really does feel like you are playing the same riff twice!


Enabled via the soft bypass footswitch, GEMINUS accurately replicates the minor differences that exist between two separate recordings. The TDT WIDTH control spreads your doubled tracks, anywhere from completely centred (0%) to 50% left and right (centre indent) and 100% left and right split.



KMA has carried out extensive research on how to make double tracking sound exactly how they think it should perform. In the process, they've spent thousands of engineering hours working on our own proprietary technology, even developing our own custom neural network AI with onset detection in the process for our algorithms.

The mode for the TRS input and output jacks is selected by the toggle switch. You can choose between stereo in and out, mono in and stereo out or mono in to mono out, so no matter your signal and tonal desires, GEMINUS will fit into your rig with ease.

For the most accurate performance (and just like the real double tracking scenario in the studio), their custom True Double Tracker algorithm should ideally be fed with a mono signal. Obviously if you are trying to emulate what traditionally happens in the studio, you wouldn't normally double up a stereo source. Having said that, the TDT algorithm has been optimised to still have a useful and very pleasing widening effect on stereo input signals, just take care that using too much doubling on some stereo sources may cause your carefully crafted reverb, delay or other modulation effects to turn to mush or even add phase issues.

To help tailor the Doubling to your own taste, the TIME control changes the timing range of the doubled AI-driven onset detection. Essentially, it's all about the tightness of the doubled signal to fit differing playing styles. Variable from an extra tight mode, that's perfect for extra fast riffs, to a looser timing that can just the right amount of density to more open playing styles, this control is a powerful weapon to make your riffs fit your musical goals. The centre detent is GEMINUS' default factory position, but turning the knob left will give a tighter feel. Crank the knob to the right and the doubled signal becomes much more relaxed.


While the LEVEL control affects the balance of the doubled signal against the original source. Useful for those times where you might want maximum width, but a little less (or even more) of the sound to be doubled against the original. Centre detent of the knob is GEMINUS' default factory position. There's some clever panning stuff going on under the hood here too, so neither the doubled or original signal is louder on one side or the other, when in Stereo.

Finally, the new PITCH selector switch can add some additional movement to your doubled signal, extending the usefulness of GEMINUS beyond standard doubling. When the switch is at the centre default position (-) there is no pitch adjustment, (~) adds some subtle modulation, while (?) adds even more wobble. In this mode, it doesn't mean that your second guitarist will sound like they are off on a quest for enlightenment all on their own (!), it is just super handy for those times when you want more chaos and instability in your ensemble.

To top it all off, they've added a switchable real True/Buffered bypass and 'silent' relay-based soft switching. When KMA were testing our new pedal platform, they really loved the clarity and signal integrity of KMA's Buffered Bypass, plus there are zero clicks and pops when switching in this mode, which is why it is the recommended and default mode on shipping. However, they know some players have some special devices like extra fussy vintage fuzz pedals and the like, so they added the ability to select True Bypass mode via an internal dip switch.

Phew, seems that there's quite a lot going inside GEMINUS then. We believe our True Double-Tracker in this pedal is the best sounding, yet easiest to use doubler you'll ever play - period.


Go forth and multiply your riffs!

Notes: Amazingly versatile phaser business in this brilliantly designed pedal. Watch the demo video to hear the amazing range of sounds this one can do. Best phaser ever? Might just be.

Supplier's Notes:

Jump into spaceship Horizont and begin your trek into star- filled galaxies, all while discovering the incredible vastness of the sounds created by this inter-dimensional multi-spatial stereo analog JFET Phaser. The unexpected is waiting for you behind the far away horizon and it will be a journey you'll never forget!

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, KMA 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.

The envelope can be set to upwards or downwards operation via the ENV switch, seeing the LFO either slowing down or speeding up, or flipping the orientation when phasing manually from lows to highs and vice versa. In conjunction with the FUEL (Sensitivity) and the DECAY controls, the envelope can be tailored perfectly to your needs.

The EMPH (Emphasis) mode from the original Astrospurt Phaser was kept, but have reworked and refined it extensively for the Horizont. The four toggle-switches determine the stage in which the phase-shifted signal is fed back into itself, while the REG (Regeneration) control sets the feedback amount. We also smoothed out the overall sound of the EMPH mode for a more pronounced, and crisp vocal-like tone. Each of the different switch variations and turn of the REG control will yield different results, seeing you discover new wild, fuzzy and noisy galaxies as you travel deeper down this sonic wormhole.

In order for you to levitate through spacetime, a stereo output has been added 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, the Horizont was equipped 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.The pedals' headroom was also increased 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.
