The multi/poly module from KORG draws inspiration from the legendary mono/poly analogue synthesizer from the 1980s, which was known for its big sound and experimental features thanks to its 4 oscillators, and transfers this concept into the modern age with the help of sophisticated modelling technology. It uses the latest generation of KORG analogue modelling, which, in addition to the detailed reproduction of classic oscillators and filters, for the first time also includes complete voice boards with the interaction of qualitatively different components, envelope generators and even portamento behaviour. In this way, the multi/poly module creates sounds that seem almost alive and have the typical "analogue" timbre. The available "Classic", "Digital" and "Waveshaper" oscillators, which can of course be freely combined with each other, offer a real playground for sound designers and synthesiser fans. Within a sound programme, 4 oscillators, a noise generator with its own filter and saturation as well as a ring modulator are available. In combination with the dual filter, the flexible cross-modulation known from the Mono/Poly, four loopable DAHDSR envelopes, five LFOs and six modulation processors, there are no limits to the imagination when creating sounds. Within a "Performance", up to four such sound programmes can be created as "Layer". "Split" or "Layer Rotate" sounds to create particularly complex timbres. ("Layer Rotate" is a function inspired by the classic mono/poly and switches between different sound programmes each time a button is pressed in "Round Robin" style) To animate these sounds, the "Motion Sequencing 2.0" function offers several independent sequencer tracks for timing, pitch, shape and four other parameters, each of which can be recorded as individual steps or in real time. As if that wasn't enough, the "Kaoss Physics" function provides additional, unique modulation options based on the physical model of a virtual ball that moves on a plane based on previously defined parameters and can be controlled or triggered using the integrated X/Y touchpad. This ball generates eight different modulation signals at any given time, which can affect almost any sound-shaping parameter. This creates complex modulations that are never exactly repeated and can be used particularly effectively in a live context. Three blocks with studio-quality effects as well as a master reverb and a master EQ round off the sounds accordingly. When switching between different sound programmes, the "Smooth Sound Transition" familiar from the KORG flagship workstations ensures natural-sounding transitions without tearing off the sounds or effects. An inspiring random function is available for creating new sounds, which randomises all or only certain sound-shaping parameters within a previously defined framework at the touch of a button, which can lead to completely new timbres or useful starting points for further sound experiments. With the exception of the pitch bend and modulation wheels, the multi/poly module offers the same controls as the keyboard version, allowing all parameters to be set directly on the device. The compact housing can be placed either in a 19" rack or on a desk, whereby two different installation angles can be selected for the latter variant. The connection sockets are positioned so that the cables are still accessible even if other devices are installed in the rack directly above the module. By supporting the MIDI 2.0 Property Exchange Standard, the multi/poly module also communicates independently with other MIDI 2.0-compatible devices such as the Keystage MIDI Controller, making time-consuming MIDI mappings a thing of the past. Free editor/librarian software for Mac and PC is also available for particularly convenient programming of the multi/poly module.
