Bastl Instruments - Kastle V1.5

Kastle from Bastl Instruments is a mini modular synthesizer which runs on 3 AA batteries. It delivers the fun of modular synthesis at a low cost and fits into your pocket so you can play it everywhere! It has a unique digital lo-fi sound and it can be melodic as well as very noisy and drony, soft or harsh. It is designed to be fun on its own but it is most powerful when combined with other modular gear. The new v1.5 version combines a complex oscillator and LFO with stepped waveform generator.
