Characterizing Volca Sample’s Low Pass Filter

I’ve been preparing a couple of Volca Sample tutorials before going on vacation, and this question came up when presenting the low-pass filter. What kind of filter does the Volca Sample ships with? in order to test it, I used sample 27. This sample is a small snare with not too much bass and quite a lot of white noise. I recorded this sample being played with the filter at 127, 110, 100, 90, 80, 70, 60, 50, 40, 30, 20, 10 and all closed. At first glance, the filter sounds like a 12dB/octave one. Figure 1 shows the wave shape of those samples (A), and their corresponding spectrogram (B).

This month’s header

This month’s header was made with GIMP, using the Fractal Explorer. It is a fairly large area or Julia’s set (CX = 0.322; CY=0.416). The bottom left corner is near (0.25,0.25), and the top right is close to (0.5,0.35).


New Video, New Channel!

So in the last few months I’ve been considering opening up my hobby of making music (electronic music in particular) and start publishing some of my stuff. This lead me to make the not-so-short video on hooking up a MicroKorg and a Volca Bass.

But today I decided I should do some quality stuff if I’m serious about sharing my stuff with the rest of the world, and therefore launched my public YouTube channel, Philip+. To mark the occasion, I made this cover of Guru Josh Project’s song “Infinity”.
