I thought it was the moog taurus pedal? you could do minitaur and a behringer midi footswitch or an expensive midi lever pedal. but you could literally just get a behringer model d, arturia keystep, and a cheap sustain pedal to hook into the keystep. those are really the two cheapest options in the peak analog bass quality realm, minitaur and model d as far as price is concerned. because a model d is a clone of the minimoog which is a killer bass synth. but from what i have seen and heard i believe serum is a very capable digital alternative so if you got an amazing pc rig you could just get a midi keyboard maybe with aftertouch, pitch and modulation wheels, if you are decent or want it. and will need a sustain pedal, and vst.
if i can win the lottery i would get one. LMAO
as ed bassmaster would say, “Just look at it!”
man fader foot sliders for frequency and loudness
