This synthesizer took me about a year to make. I spent as much time making it look beautiful as I did on the electronics. It is an improved version of a previous synthesizer, The Machine. The main improvement I made is that this one is a lot more reliable. I had so many problems with the other one breaking down on stage. This one hardly ever goes wrong. Another feature is all the coloured lights, they let me know what switches I have switched on. This is very useful on stage when you need to change from one sound to another very quickly.

Never again!

Ribbon Controller

It has 2 ribbon-controllers so you can play 2 different notes at once, but this is a skill I have not yet mastered. The ribbon controllers are wire wound variable resistors the wire is 1 tenth of a mm, very fine, over 6000 turns. It is wound onto plastic rods, the resistance it about 10k.

Playing with a ribbon gives you a similar sound to a theremin, except it is a lot easier to play in tune because you can see the notes marked out along the ribbon. I prefer the sound of a ribbon over the sound of a keyboard with portamento. The problem with portamento is that you can't time when you glide into the notes only when you glide out of them. Portamento sounds more kitsch to me than a ribbon controller.

Ribbon Controller

I play the ribbon with 2 sharpened toothbrushes, one in each hand. I find the plastic on cheap toothbrushes slides well on the metal. I have only recently mastered the 2 toothbrush technique. It is very expressive because you can use a combination of slides and keyboard style jumps.

Patch Bay

This synthesizer is modular, the patch bay is 2.5mm jacks. There is a switch to change it to internally patched. I used miniature relays to do this. The internal patch is what I use on stage.

Ring Modulator

I have made an old fashioned diode ring modulator. This is a simple circuit using germanium diodes and LT44 output transformers. I prefer the sound of this type of ring modulator over modern designs using multiplier chips. It is normally described as a passive circuit, but I have used buffer amplifiers on the inputs. I found you get a better sound if you get the signal levels just right on the inputs. In the first sound I am blending between normal and ring-mod

Here is a picture of the valve distortion circuit. As I have very little space I decided to use a miniature nuvistor valve. It is a class A triode circuit which means very soft distortion and lots of 2nd harmonics because of the way it squashes the wave asymmetrically.

Harmony Switches

Photo of the inside of the harmony switches

The harmony switches let me select pre-tuned intervals between the 2 oscillators. The latching switching is done using 1950s computer techniques, neon bulbs and relays to make simple memory elements to remember the selector switch position. I could have used CMOS multiplexers but that would have bored me to death.

Your idea is simply amazing! It was so inspiring that made me want to build my own reverb rank unit (of course, MUUUCH more simpler!)

I have some questions..

1) do you have some recordings of this unit used with drums, vocals or guitar? i would love to hear it! the "horror" sounds are reeeally high quality, so i wanted to hear how conventional music sounds with it!

2) it is ok to use a guitar pickup to pick the sound of the springs instead of a mic amplified? my idea is to avoid having to amplify the reverb signal again to mix with the dry signal.. so i thought of placing a magnetic pickup and connect the output (with a pot for volume) in parallel with the dry signal. It would work?

Message: Your synths are truly inspiring. Each one a work of art and a labour of love. This is what a synth should be like. Colourful with big knobs to tweak. You are really clever to be able to do this. Have you heard of Stephen Hobley's home made laser harp? It took 22 years research. Plans are on his site for $19. You might enjoy making one! You might also like the Narrow Bandwidth Television Association who build early style TVs, they could help you to make a synth with a visual display. Why not use an old pintable and instead of scoring, each target hit triggers a sequence for a random musical piece?

I found that every thing that is connected to the diode ring needs to be isolated from each other. The center taps connect directly to the diodes beacause the are on the same windings.

Message: Hello,

I can't explain it all fully, but this page gave me SO MUCH JOY. Your adventourus spirit, your very straightforward way of explaining painful lessons you've learned made me laugh loudly! And your machine is JUST SO DARN BEAUTIFUL!!!! It's like magic: all the colors and knobs - it's as if from a dream I had. My favorite samples were the filterditortion and harmonyswitch wavs. Very 80's vintage Dr Who or horror flick vibe - which I simply love to death. Great tone and texture in parts and I wonder how you created your arpeggiation. It makes me want to know more of the dirty bits on how you got those sounds. I originally came to your page as I was about to read some ancient words from 3,000 years ago (Isaiah) but needed some background noise to mask all my cat's licking and picking sounds.

One question: Is the variety in a single modern synth, say the Korg Z1 (which I have) simply a matter of endless hours of programming the roms associated with the chips so that the level of variety produced by a team of Korg developers is unassailable by a one man show like yourself, even if your beast has more modules? Or could your synth exhibit this same variety, even if the wav's don't reflect all of it?

God bless!

The wire is 0.1mm enameled constantan which I bought from 'The
Scientific Wire Company' (east London) I used 1200 grit paper to remove a strip of enamel after it was wound. You can probably get away with 0.2mm wire without hearing steps in the pitch, 0.1mm is very frustrating to work with.

I'm interested in making one, and have been trying with Svhs video tape, but it's flimsy. I do understand the elektronic idea behind it, and i can see those thin copper(?) strips suspendid with the springs, so far so good, but when you press those, how does it make contact ? cause you wrote the resistors are wire wound plastic tubes ? but to make contact,the wire should be bare, but a coil of bare wire wouldn't be a coil really. so, what am i missing ? i really hope to hear from you, cause i love the design, looks very sturdy.
