Oscillator quartet

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. Classic generates the familiar standard waveforms along with special features such as pulse width, triangle slope or Mix of a combined waveform. Digital has 200 waveform banks with 64 waveforms per bank, i.e. wavetables. Waveshaper is a fairly complex affair that generates the results of Buchla oscillators, among other things, and has a total of 90 different algorithms. Just think that this impressive selection is available for one oscillator. However, a layer has four oscillators and a performance preset has four of these layers. This means that 16 different oscillators can be played in one performance preset! As this is a modernized version of the MonoPoly, synthesis features such as noise generator, ring modulator, hardsync and cross modulation are of course included. Simple sounds consisting of a single oscillator, filter and envelopes are also possible. To do this, simply switch off layers 2-3 and oscillators 2-3 of the first layer.

Filters

There are plenty of them in the multi/poly module: 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.

Kaoss Physics

The pad in the middle 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.

Modulation & sequencer

In addition to the usual modulation sources such as velocity, polyphonic aftertouch 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 Gate time, which can be cleverly combined to create polyrhythmic sequences. Recorded controller movements(Motion Sequence) do not have to run through the entire pattern; they can be played back individually shortened as a loop for each track. A versatile adjustable arpeggiator acts as a further playing aid.

The module

The module version offers all the features of the push-button models, but as a desktop-compatible 19" rack unit, it takes up very little space. Mounted in the rack, 4 HU must be kept free; no extra space is required for the cables as the connections are recessed in the housing. There are two installation angles on the table, which vary when the rack ears are mounted upside down.
