FILTERS? Build a simple DIY passive electronic low pass filter.


Make your lemons into a synth with this circuit :-–5fIA

heres the schematic for the active filter, made by rene schmitz based off an MS20 filter, this forum is useful for it :-

Super simple build!

1 10k pot and 1 100nf ceramic capacitor and 2 jack sockets
mess around with values! and types of capacitors. the larger the capacitance and larger resistance, more frequencies filtered!

even try electrolytic capacitors! all the way up to 470uf! give it a go.

im having trouble understanding midi to cv… a module i bought has a 1vt/oct input and i wanna know what my options are as far as sequencing a melody. i have a midi to stereo cable! is there a DIY mod option where i can get just pitch cv signals from the cable? in your previous videos i saw you built your own midi to cv modules so i thought you might be the guy to ask 🙂
