Introduction This is the source for an Arduino based low latency octave switching device, intended for use with keyboards who lack or have hard-to-access octave switching facilities, such as the ...

One of the great joys of Hackaday are the truly oddball requests that we sometimes get over the tip line. Case in point: [DC Darsen] wrote in with a busted 1970s organ in need of a new top-octave ...

We got a question from [DC Darsen], who apparently has a broken electronic organ from the mid-70s that needs a new top-octave generator. A top-octave generator is essentially an IC with twelve or ...

Abstract: Frequency response method is an important approach in the design and analysis of plants and controllers. Bode plot is a simple technique to graphically represent a system frequency response.
