Here’s the new analogue (or analog if not British) thru zero FM oscillator the ‘EN129’ from Dannysound. The module offers great, analogue, through zero frequency modulation with is musical and responsive offering for dynamic modulation without the wide ranging pitch drift in exp/log response analogue FM circuits. There is an additional LOG FM input and attenuator so you can exploit two flavours of FM and their responses. There’s coarse and fine tune, LFO button to drop the range, sine, triangle, pulse, square and saw outputs. The pulse has PWM control and inputs and the saw has some rather unique onboard shaping too.
