This is Tona from Instruo. It’s a 12HP saw core analogue VCO with the usual square, saw/ramp, triangle and sine wave outputs but there’s also an on board wave folder that takes the sine and uses a slider to create the fold level as well as a CV input and attenuator to modulate the folding. There’s also a sync and linear FM input. It tracks well, sounds great, and works great with the Ts-L as a complimentary pair of oscillators.
