Belgrad vs the Newcomers @JohnSchussler

Uploaded August 2026 | Updated September 2026, 3 weeks ago

There are a variety of dual filters out there, and there are certainly others that give Belgrad a run for its money. But in this case I have these two new filters, Double Bubble and Ceremony, and with Belgrad close at hand comparing them seemed to make sense.

Obviously the interface is very different on each, so part of the question is how you like your dual filter setup. But part is also sound, and what happens when you start fiddling with the knobs.

So that's mostly what this is, me fiddling with knobs and seeing what comes out.

$Neutral Labs: Pip clocked cv generator Along with Nijel (see previous vid), Martin at Neutral Labs sent along a kit for Pip, his new clocked CV generator. Its main selling point is the synchronization between the two channels: channel A can run at a multiple or fraction of channel B, and both are clocked so theyll stay in sync with the beat. You can get some interesting rhythmic sounds out of your modules that have two cv inputs by using contrasting waves and different ratios (there are 16 pages of waves, each with two waves that can be morphed to make new waves). The most interesting part, however, is when you self-modulate it. You get the benefit of the synchronized channels, clocked, plus interesting little additions that bring the whole thing to life (Spoiler alert! Skip to 23m22s for my favorite bit). VCO: Chainsaw.
