Electric Druid

This article is a follow-up to my 2015 post about the distorted pitch shift you get when applying modulation to a BBD clock.

Pretty much every synthesizer has a lowpass filter, but far fewer include a highpass filter.

I’ve often seen it said online that the LM13700 is just two CA3080’s in one package.

The Jupiter 4 was Roland’s first polysynth in 1979.

We’ve recently started stocking Alfa’s clone of the famous old Roland IR3109 filter chip.

Let’s continue our deep dive into analogue drums with a look at something even earlier – the Korg KR-55.

I recently saw an advert for the new EHX Slapback Echo reissue pedal and thought it was a cool little thing and would make a nice project.

The Boss Dr Rhythm DR-110 was introduced in 1983 and was the second drum machine Roland had made under the Boss label, following the frighteningly basic DR-55 in 1980.

I was exchanging a few emails with a customer recently, and they suggested designing a chip that allowed you to define an LFO shape with a set of controls – obviously sliders would be perfect for something like this, like a Graphic EQ for LFOs!

First, a quick history of overdrive pedals.
