Bastl Instruments released Kastle ARP

Bastl Instruments released Kastle ARP, a unique modular melody generator based on a quantized sine wave oscillator with a digital waveshaper.

The pitch selection employs straightforward concepts to unleash surprising intricacy. The quantized oscillator ensures it is always in tune, and its pitch can be selected using the NOTE and CHORD inputs. The decay envelope adds variation by occasionally skipping pitches before retriggering. The timbre control allows you to blend between noble sine waves and 8-bit chip-tunes.
