The multi/poly from Korg is the modernized and expanded virtual-analog version of the popular Korg MonoPoly The digital synthesizer uses Korg's latest generation of analog modeling technology for sound generation, which impresses with incredibly authentic sounding filters and oscillators. Part of this synthesis is also that virtual voice cards generate natural timbre variations. The structure of the original MonoPoly has been largely retained and supplemented with a sea of waveforms for the oscillators as well as a second filter, numerous effects and extensive modulation options. In contrast to the over 40-year-old original, the multi/poly is truly polyphonic, as the 60 voices are spread over four layers, each of which contains the complete voice architecture. Another special feature of the MonoPoly has always been the ability to play the oscillators alternately with each new note. This is still possible; the multi/poly goes one step further and even enables layer rotating, which plays a new sound with every keystroke! All in all, this synthesizer produces sounds that you would most likely create with a lavishly equipped, polyphonic modular system. Pretty much everything can be modulated and the arrangement and distribution of voices is one of the most complex to be found in the

The oscillator section has the same structure as the MonoPoly, but offers much more than the four original waveforms per oscillator. First, you select for each individual oscillator whether it is to be equipped with Classic, Digital Waveshaper.


There are plenty of them in the multi/poly: twelve filter models have been implemented to suit every taste. These include the Korg classics MS-20 Lowpass and MS-20 Highpass, which have a much more biting sound, the powerful, round MonoPoly filter, successful replicas of the classic filters Minimoog, Prophet-5 & SEM, Transistor Bandpass & Highpass, as well as some of Korg's own resonant developments and a special multimode filter. The real highlight in the filter section, however, is that two filters per layer can be used simultaneously with serial or parallel routing. In this way, the serial dual filter of the Korg MS-20 can be simulated or, for example, the low frequencies can be processed with two completely different low-pass filters.

The effects section of the multi/poly has a lot to offer. There are three effect blocks per layer(!): Pre-FX > Mod FX > Delay, and in this exact order. Pre-FX provides various distortions, specialized EQs, compression and decimator.


The pad in the top left is much more than just an X/Y pad controller that can be assigned to different targets. The control panel controls a modeled sphere that is nudged in a definable environment. To put it simply, it's like mumbling in a sandbox: a hollow, a hill, the nature of the surface; all of this contributes to the movement of the ball. These movements, jumps and, depending on the position, resting states can be assigned to synthesis parameters for modulation.

In addition to the usual modulation sources such as velocity or the modulation wheel, five LFOs and four envelopes bring the already complex sounds to life. Anything that is not directly assigned or is to modulate more than one target can be animated with additional entries via the modulation links. The polyphonic step sequencer allows the integration of most parameters, including timing and
