Frap Tools CUNSA in-depth tutorial | Eurorack quadruple multimode analog filter module

video upload by Frap Tools

"Time to dive deep into Cunsa's main features! In this first tutorial, we will explore how a single filter works and how to combine them together to get the signature "Cunsa sound." This should get you started with CUNSA and let you understand its basic functioning. In the next episodes, we will see more specific applications!

00:00 Intro & Cunsa overview
02:21 The 12 dB/oct lowpass filter
02:41 The Q parameter (resonance, emphasis)
03:42 How the Q affects the LPF cutoff point at 12 dB/oct
04:15 The Character parameter
