Bastl Instruments Kastle Arp

MUSICAL FEATURES

BASTL INSTRUMENTS' KASTLE ARP is a unique modular melody generator based on a quantized sine wave oscillator and digital waveshaper.

Pitch Selection removes complexity and employs easy-to-understand concepts. The quantized oscillator is always tuned, and the pitch can be selected from the NOTE and CHORD inputs. The Decay Envelope can be retriggered to skip pitches and add variation. Timbre control lets you blend noble sine waves with 8-bit chip tunes.

It functions as a full-fledged modular system and is also compatible with the Eurorack modular system. You can perform many functions such as six syntheses, unique wave shapers, random steps, LFOs, etc. with free patching.
