POSITRON 16 is an analog polyphonic synthesizer concept that focus on morphing, with continuously variable waveforms, filter modes, arpeggiator patterns and more.

It features plenty of hands-on controls, from the three wheels, the Morpher joystick and a fullwidth ribbon controller to polyphonic aftertouch, macro controls, dual pedal inputs and even a CV antenna socket. This will make sure you are always in control of your sounds and performances even during improvisations, and the intuitive LED-collar encoders with push button function make creative sound programming a breeze.

Dual classic VCOs

The POSITRON 16 have two analog oscillators per voice, with 5 waveforms continuously variable between sine, triangle, saw, pulse and tone mod. The oscillators are classic 3340 VCOs, with a warm but powerful sound.

In addition to the VCOs, the oscillator section also features a dedicated Detune control for immediate fatness, both soft and hard oscillator sync, a very musical Ring modulator with its own modulation LFO and an easy-to-use FM control for more complex wave shapes.

Signal source mixer

The two oscillator outputs go to the 5-channel signal source Mixer, for balancing levels and routing them to either or both of the filter channels.

A powerful Sub oscillator is available with adjustable sub octave and either sine, triangle or square waves, for adding some depth to your sounds.

Pink or white noise can also be mixed in with the other signals and routed in the similar way, as well as an external audio in for running stereo sources through the filters, amp and effects.

Twin filter channels

The 5 mixer sources can be routed to either or both of the fully featured filter channels, each with its own multimode filter circuit.

Channel A is built around the Behringer Moffatt solid state filter, with filter modes morphing from lowpass to bandpass/notch and high pass. A highly visible red cutoff encoder makes sure you will always know where to adjust the filter, and resonance, envelope and LFO mod controls completes the section.

Channel B is identical to A but has a 3320 multimode filter instead of the Moffatt, for extra warmth.

In between the two filter channels reside the global filter controls, with a Cutoff Link button and an Offset encoder for convenient control of both filters at once. Next comes the routing encoder that let you morph from parallel to serial in endless ways, and finally a stereo spread/mix control for placing the filters in the stereo field.

Amp, effects and mod matrix

The two filters are routed to the Amplifier, where you can set the stereo width and/or pan of your sound as well as adjust the overall level.

Next in the audio chain are the 4 Multi effect engines, that offer reverb, delay, chorus, phaser, flanger, overdrive, compression, EQ, amp simulation and more. The engines can be combined in a number of routings, including serial, parallel or combinations of both, as well as feedback configurations for effects like shimmer reverbs and more. The comprehensive 16-slot Mod matrix that let you use any of the 38 sources, including joystick, ribbon controller and the optional CV antenna, to modulate any of the more than 175 destinations including sequencer, arpeggiator and effect parameters.

Morpher joystick

The powerful Morpher section, with its LED-collar joystick. allows you to completely change your sound by the movement of the joystick. Multiple values can be controlled by each axis for quick and easy sound design on the fly. The movement of the joystick can also be recorded into an XYZ-envelope, with optional loop-feature, for wavetable-like effects.

Envelopes

The POSITRON 16 have 4 high-range envelopes, with one each for pitch, filter and amp modulation as well as an extra mod envelope. Each envelope has 5 stages – delay, attack, decay, sustain and release – as well as a loop option for LFO-like effects, all the way up to audio rates.

The frontpanel has two identical sets of envelope controls to allow for tweaking two at-the-time, and 4 selector buttons for assigning any of the envelopes to any set of controls.

LFOs

Below the envelope section can you find the 4 powerful LFOs, each with rates from 30 seconds up to audio rate. The LFOs feature 6 continuously variable waveforms, including sample & hold, and a shaper control let you further tweak the selected wave shape by adjusting its pulse width, symmetry or smoothness.

The LFO rates can be synced to internal or external clock, and each LFO can be set as monophonic or polyphonic for anything from vintage polysynth behaviour to complex phase-shifting effects.

The arpeggiator

The onboard arpeggiator is very flexible and creative, and features stepless morphing between arp patterns, gate length, note density and randomize controls for endless variations of the selected pattern. Octave range can be set from 1 all the way up to 5 for full keyboard-with effects, and the tempo can be set to master clock or as adjustable beats like 1/4, 1/16, 3/8 and more.

There’s also a very creative Custom-mode, where you can define your own patterns with full control over note order, rhythm and velocity offsets. Using the graphical display, you can easily see and edit even very complex patterns with ease, making this a performer’s dream.

Step sequencer

The built-in 16-step sequencer is an easy-to-use but powerful tool, allowing you to create anything from simple looping sequences to key-triggered transposable musical phrases. The sequencer also features motion control, for recording and playing back parameter changes in sync with the music.

The Program bank and Patch select buttons double as sequencer step buttons, so that you can enable or mote steps in real-time for creative performances.

Dual mode

One of the most powerful features on the POSITRON 16 is the Dual section, with its intuitive Panel morph function. Each program patch consists of an upper and a lower set of values for all continuous controls, and the Panel morph encoder allows you to seamlessly morph between them. This can create anything from subtle effects to drastically different sounds available with a single control.

The 2 panel sets can be configured in layers for morphing from one set to the other or as spans across the keyboard for sounds that change from the lower end of the keyboard to the upper. Using Panel morph together with the Morpher joystick allows you to create sounds of incredible complexity that are still simple to control – and all while keeping the full 16-voice polyphony.

Voices

The POSITRON features 16 fully analog synth voices, with an optional Unison mode for stacking 2, 4 or more voices to create very powerful sounds.

The Voice detune encoder controls the amount of pitch detune between voices, which in combination with the Unison mode easily creates incredibly fat and wide sounds.

The Drift control will make certain parameters like pitch, filter cutoff, envelope times and LFO rate vary over time and/or across the keyboard. This will create anything from a vintage feel to your sounds all the way up to the effect of a neglected old synth in desperate need of a tune-up.

Connectivity

The POSITRON 16 comes fully equipped to connect to your existing (and future) gear. The backpanel holds sockets for MIDI of both classic 5-DIN and modern USB variety, and the stereo audio outputs are balanced for the best signal quality. Stereo audio in will let you run any of your other instruments or other sound sources through the POSITRON and take advantage of its powerful filters and multi effects.

Apart from MIDI, there’s also classic CV/gate sockets for connecting to vintage synths or modular systems, and a clock in/out will let you sync with your drum machine or analog sequencer.

The twin pedal inputs accept both expression and switch pedals for maximal flexibility, and last but not least there is also a BNC connector for attaching an optional analog antenna for Theremin-like effects.

Keyboard and controls

The POSITRON 16 comes with a semi-weighted 5-octave full-size keyboard with attack and release velocity as well as both channel and polyphonic aftertouch. Any aspect of keyboard playing can be used as a modulation source, including which key you hit – or how many.

Above the keybed sits a full-width ribbon controller with LED-indicators for each key. It can be used in a number of ways for sweeps, bends or vibratos, or even Ondes Martenot-style playing where the pitch is set by the ribbon’s contact position and the gate and volume by pressing any key."
