Wow! I didn't know All Pass Filters could do this // 3 Patches with dapf from Instruo

*DON'T MISS THE EXCLUSIVE PDF PATCHBOOK!*

I'm always striving to learn and explore with sound and music and dapf (the new Eurorack module from Instruo) certainly brought a big slap of school day into DivKid HQ. I was aware of all pass filters, getting past the funny idea that "all" frequencies pass (so what's the point?) and knowing they were use for phase shifts. What I didn't know is how core and important to filter topologies they were and how creatively useful they could be.

Some exploring later and here we are, with 3 patches that really show the power of phase manipulation. While dapf makes a fantastically chewy phaser FX unit I didn't expect it would be such a great stereo expander for a single VCO nor did I know I could be MUSICAL and totally analogue 3 operator FM/PM (like the digital Yamaha DX and Casio CZ phase/FM methods) synth.
