Bastl Instruments has announced its latest instrument, the Kastle ARP, a pocket-sized patchable synthbox with “uncountable melodies to explore”.
It’s a unique modular melody generator based on a quantised sine wave oscillator with a digital waveshaper. It’s always in tune and its pitch can be selected using NOTE and CHORD inputs. The decay envelope adds variation by occasionally skipping pitches before retriggering. The timbre control allows you to blend between Nobel sine waves and 8-bit chip-tunes.
The versatile LFO section, taken from the original Kastle Drum, combines simplicity with complexity.
