Cherry Audio's KR-55C is a supercharged, best-of-both-worlds software emulation that combines features from two lesser-known drum machines of the post-punk era: Korg's "Rhythm 55" KR-55A and KR-55B. KR-55C boasts all the rhythms from both models, for a total of 240 factory patterns, intros, and fills. Additionally, it adds 200 original patterns and kits that cover a wider range of genres. KR-55C's user interface shifts based on whether the A or B model is selected and includes extra pages that let this beatbox "step out" even further. It features a familiar X0X-style 16-button layout for step-editing and real-time pattern programming, as well as a song mode for chaining up to 99 patterns.


Unlike sample-based instruments, Cherry Audio has emulated the Rhythm 55's tones through analog modeling. The Instrument Edit panel allows extensive parameter editing like tuning and EQ for each instrument, enabling a range of sonic possibilities far surpassing the original. The Mixer and Effects sections allow for separate processing of each sound, with features including panning, mute/solo, overdrive, flanger/chorus, delay, and reverb. It also includes a bus compressor and limiter for master amplitude control. KR-55C offers DAW-friendly features such as auto-sync, drag-and-drop MIDI export, individual outputs, and complete automation capabilities.
