Korg Krome -73 EX Workstation

Synth focused on packing the most usable sounds into an easy to use platform, has received a major refresh. Updated to meet the needs of the current music scene, KROME EX has a special emphasis on sounds that can immediately fit into productions of all types. In addition to standard sounds that will never grow old, KROME EX provides numerous new programs and PCM data, including piano programs prepared specifically for this product. This instrument provides high-quality and immediately-usable sounds that take full advantage of the KROME's high performance specs. The new body also features a newly revamped build and look to accompany the new sounds. A music workstation for gigging musicians and producers of all stripes.

Oscillators: 2

This dual-oscillator synthesizer offers a wide range of sonic possibilities that combine harmonic and non-harmonic tones. Users can adjust the frequency and amplitude of each oscillator separately, allowing harmonious layering of sounds, creating unison effects or captivating modulations.

Headphone Output: Yes

The headphone output allows direct connection of headphones for private listening. This output provides a convenient way to enjoy the sound without disturbing others or ambient noise.

MIDI Interface: Yes

It supports MIDI, allowing you to connect and communicate with other MIDI-compatible devices. This feature extends control and integration into the larger music environment, increasing flexibility and creativity in music creation.

Polyphony: 120

The polyphony of this instrument allows up to <%=tp_value % notes to be played simultaneously, providing rich and complex musical possibilities.

Arpeggiator: Yes

The Arpeggiator transforms chords into sequences of individual notes played in various rhythmic and melodic patterns. Instead of playing the chords as a harmonic whole, the Arpeggiator breaks the chords into individual notes and plays them sequentially according to the selected algorithm.

Modulation: Yes

Modulation allows you to change different aspects of the sound in real time, opening up a wide range of creative possibilities. For example, it can affect the pitch of the sound, creating a vibrato effect, or it can change the amplitude of the signal, creating a tremolo effect. It can also adjust filtering to create smooth transitions between frequency bands and dynamic textures. Modulation can also be used to change the character of the sound depending on the time or intensity of playing, giving the sound a lively and moving character.
