This short article discusses an add-on to the following:
The Brute: A 3-channel Audio Amplifier For Leslie Speaker Emulation.
Treslie: 3-Phase Leslie Speaker System.
LEM: Leslie Emulation Control System using PIC Microcontroller (18F26K20) based on Pequeno board, (Arduino-alike) and 3 DACs.
Shortly after completing LEMS, The Brute and Treslie, (see links above) it became apparent to me, that [...]

This post describes the design and construction of a Leslie Speaker Emulation System (LEMS) control unit, based around an 18F26K20 PIC Microcontroller. The unit is intended to be used to split an audio signal into 3 phases, amplitude modulate these and feed to a Leslie Speaker Emulation driver unit [...]
I recently completed and implemented code on a PIC18F4620 to talk to my two DB50XG units. Since the code is in ‘C’, and might prove useful to others implementing such code, I’ve provided a hard-copy (DB50XG.c) snapshot of the relevant sections from my code and give a brief extract of these below.
The XG Voice List [...]

How chords are formed
Before discussing the processor board and software, it is worth mentioning how the chords are composed. I have provided the table below which [...]
For some time now, I have experimented with producing MIDI signals from a Guitar. Yes, I know there exist a choice of existing systems, but they all have both limitations and drawbacks, the worst of which are:
Limited to certain Guitar Models
Irreversible changes required to fit
Unsatisfactory string-bending capability
My documented antics with guitars have created much [...]
I’m always a little curious to see what posts are popular, and why. This involves checking the statistics on the site, and can be an eye-opener.
I’ve listed the Top 10 posts obtained from the stats this morning, and these are given below for your information. My assessment is that most readers of the blog seem [...]
Most Guitar-to-MIDI converters are a grave disappointment. Recently, I’ve been playing with the idea of adding electronic scanning to one of my guitars and using this to output MIDI – it works but has several disadvantages, not the least being that it involves irreversible surgery to a guitar. My prototype is a £35 (GBP) second-hand [...]
First take a look at the specifications listed alongside. Look familiar? Well, to Waveblaster fans probably, as this is the spec. of the Yamaha DB50XG daughterboard, a phenomenally successful product in a long line of excellent audio/MIDI offerings by Yamaha.
For a while now, I’ve come across articles on using a second-hand DB50XG (or clone) as [...]
