Hello, im considering buying a System 80 jove filter but I need to know if can filter audio signals that arent from an analog synth, like a drum machine or audio from my mixer. I am making dub reaggae and I was looking for a filter that had both hpf and lpf so I could use the auxillary sends on my mixer to filter guitar and drums ect. But i could not find any video or comment anywhere of anyone ever using it to filter anything but the signal from a synth.

I found that the vintage synth lab vcf-74 has everything I need hpf and lpf and can definetly handle signals from other sources but they seem like they're hard to come by.

Any help much apreciated


a filter will filter any audio signal

the only thing to watch out for is that most non-modular signals will be significantly quieter than modular level - so you will want to amplify the input signal - there are dedicated input modules available or you could use a vca that catually amplifies the input - such as veils (or a clone as it is discontinued) which has over 20dB gain available per channel...

nb most vcas don't increase gain - so make sure if you go the vca route that you find one that has ample gain available

Utility modules are the dull polish that makes the shiny modules actually shine!!!

sound sources < sound modifiers < modulation sources < utilities

Thank you very much! I have an input module ready to boost my signals thank you much appreciated!
