The Kaossilator Pro+ from Korg is a performance interface that features an XY touch pad and four loop record buttons that can be set up for loop recording of four measures (16 beats) each. The controller allows the user to play musical melodies and phrases by simply stroking, tapping, or rubbing the touchpad. Horizontal motions on the touchpad control the pitch, while vertical motions control the tone, including filter cutoff, feedback, or modulation depth. Each of the four loop banks can be muted or un-muted, its volume adjusted, and its loop length changed, and the four banks can be combined for virtually infinite performance possibilities.

The intuitive design of the touchpad is particularly appealing to non-keyboard players, although performances can be created on the controller that could not be produced on a conventional keyboard instrument. Key and Scale features ensure that notes being played will match the song being performed. The Key setting specifies the root along with a choice of thirty-five scales encompassing chromatic, major pentatonic, and minor blues, as well as others such as Spanish, Ryukyu, and Raga. By using both the Key and Scale settings perfect solos can be played without a single wrong note. The Note Range allows for specifying the range of playable pitches.

Features: 

Loop Recording function allows intuitive performance and track making

Loop Recording can be set for up to four measures (16 beats.) Performances on the KAOSSILATOR PRO+ can be recorded into any of the four onboard internal Loop Recorder Banks. By adding (overdubbing) additional sounds one at a time, you can create amazing looped phrases that range from minimal to fully orchestrated.
The four banks can be combined for virtually infinite performance possibilities. Each of the four loop banks can be muted or un-muted, its volume adjusted, and its loop length changed, making live performance easy for anyone.
The KAOSSILATOR PRO+ provides line inputs and a mic input to allow for the recording of external audio sources as well. This makes it easy to add a vocal, or audio from any external device to any loop phrase created on the KAOSSILATOR PRO+.

Musical Scale, Key, and Note Range help create musical performances

Even if you've never played a musical instrument before, the KAOSSILATOR PRO+’s Key and Scale features ensure that the notes being played will match the song being performed. Use the Key setting to specify the musical key or “root.” Choose any of 35 scales, ranging from popular scales such as chromatic, major pentatonic, and minor blues, as well as unusual scales such as Spanish, Ryukyu, and Raga. By using both the Key and Scale settings to match the song, you can play perfect solos without a single wrong note.

Note Range

The Note Range allows you to specify the range of playable pitches. You can set this to a narrow range to ensure that melodies will be played accurately as you intend, or to an extremely wide range to allow unexpectedly dynamic and unconventional phrases to emerge.

USB MIDI, SD/SDHC card support, and dedicated editor software

With MIDI IN/OUT jacks and a USB port, it's easy to control external MIDI devices. Loop data and user settings such as programs can be stored on an SD/SDHC card. There's also the KAOSSILATOR PRO+ Editor* which provides librarian functionality for your loop data as well as a MIDI assignment editor.
