KORG KR-55 PRO Percussion/Drum Machine

The KR-55 Pro features "Real Groove Technology" which uses data recorded from actual professional musicians performing at various tempi, and is a completely different technology than conventional rhythm machines. There are a total of 24 high-quality rhythm styles, each fine tuned to provide the best possible feel, to accurately reproduce the experience of playing with a percussionist. The sounds, grooves, and phrases will play back at pristine quality even if you change the tempo, so you can enjoy playing serious jam sessions at your own pace.

Circuit is designed to inspire. Two Novation polysynths and a four-part drum machine, combined with an intuitive grid-based sequencer in a standalone box that will have you making electronic music in minutes. Hit some pads, tweak the knobs and your track will start to emerge, all locked in time and key. Play around with effects, patterns and sounds in real time, to produce your track, brimming with fat grooves and beats.
