Cherry Audio KR-55C
Drum Machine Virtual Instrument
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.
Korg's "Rhythm 55," also known as the KR-55, was introduced in 1979 as a replacement for the simpler Mini Pops 35 and Mini Pops 120 machines.
Although all of these models were preset-only with no option for user-programmed rhythms, the KR-55 represented a significant advancement.
It featured 48 preset rhythms, 16 intro patterns, and 16 fill patterns.
The flexible mixer section allowed users to easily mute or solo individual drum sounds, creating countless variations of the pre-programmed rhythms.
Legendary early synth-pop producer Daniel Miller effectively utilized this on early Depeche Mode and Fad Gadget albums, where the KR-55 provided most of the percussion sounds while an ARP2600 synthesizer supplied the kick drums, triggered via the KR-55.
