The new Sound Scaper from Error Instruments (NL) is a great (8HP) harmonic oscillator with a huge amount of sweet spots and a harmonic LFO. Not sure what that is, I just know it sounds awesome in a bigger system with lots of FX. It’s also a great audio rate modulation source.
Don’t expect a precision instrument, it’s designed to explore unknown territory and to generate happy accidents. However, it’s really musical and it can create a huge array of sounds on its own. It may be one of the best mistakes you’ll ever make.
