CEM3372 & CEM3374

Hello, I found a broken Chroma Polaris (not serviceable ) and scavenged 6 cem3372 and 6 cem3374(is this VCO useable for other projects?). I read some posts about the difference between the 3378 and the above mentioned, but I’d like to know if someone has used these before to avoid frying these valuable chips acquiring valuable informations. I’d like to add the filters to my MB4xSIDV2.  Thank you in advance

i think the 74 is a cool sort of IC , can be building block for LP HP BP … a new old stock went for 57 GBP :O, I wouldnt keep it , besides, use google

so are these chips usefull or not??? i can buy 6 cem3372 but are they usefull to connect in my mb sidv2?

There’s no existing documented midibox based 3372 project but there’s nothing stopping you from creating one :wink:
