These are the official Camel Audio demos I created for my Steamworx library (find out more at www.camelaudio.com/Steamworx-Sound-Sample-Library.php )

Each audio snippet in the demo is a single Steamworx preset with no added effects, demonstrating the huge variation you can get using Alchemy's Remix Pads. Enjoy! Martin Walker

Alchemy - This is a full track from my CD album 'The Greenwood'. Plenty of people have told me that audio snippets don't do my music justice, and that they sound much better at full length, so I hope you enjoy this! You can hear more tracks at www.yewtreemagic.co.uk/thegreenwood.php

The Shruthi-1 SDE (Sound Designer Edition) is my heavily modded SMR4-MkII filter board. If you're interested in adding any of these mods to your own Shruthi-1, I've described all details of the circuit changes and added more photos of my synth on my web site:  www.yewtreemagic.co.uk/soundworlds2.php

The SDE includes the following additional features:

1. Six filter 'FLAVOUR' options: FLAT, SOFT, WARM, GERM, HARD and EVIL, each offering different sound, resonance & distortion characters that react dynamically to incoming audio signals. The MkII version has added IR3109 'squelch and a warmer bass end.
2. Variable filter output 'FM' feedback control for seriously rubbery/squelch/wobble sounds.
3. Fixed LP4 filter has been extended to six switched filter 'SHAPES': LP2, LP4 BP2, BP4, HP2, and Notch.
4. 'DRIVE' offers some subtle to serious amplifier overdrive and distortion options (inspired by the Polivoks filter).
5. 'FEED' is part filter feedback, part circuit bend, offering a variety of tonal changes from subtle to extreme and even animated pitch jumping.
6. 'RES CMP' offers three different types of resonance compensation (essentially Moog, Roland and Korg in nature).

I'm well pleased with the results - enjoy!

The Korg MS-20 Retro Expansion is my heavily modded version of the Mini version, although the mods would also work on the original model. If you're interested in adding any of these mods to your own MS-20, I've described all details of the circuit changes and added more photos of my synth on my web site:  www.yewtreemagic.co.uk/soundworlds3.php

The Retro Expansion includes the following additional features:

1. MULTI-OUTPUTS: To supplement the existing choice of one of four OSC1 waveforms I added separate TRI, SAW and PULSE output sockets, all available simultaneously, plus a separate output for OSC2.

2. PWM: Next up was an additional input for OSC1 variable pulse width modulation, using the existing pulse width knob to control PWM level. 

3. SYNC & FM: A Sync toggle switch was added to OSC2, to lock it with OSC1 for those screaming lead sync FX.

4. An FM input was added to OSC2 with its own rotary level control, so it could be modulated at audio rates by OSC1 among other options.

5. VCO MIXER: I also expanded the existing mixer section, adding two extra input sockets, each with its own level control knob. These can be used to mix together several oscillator waveforms, or to mix in other patchbay or external audio signals.

6. I also added a more traditional transformer/schottky diode ring modulator circuit to achieve far more mellow ring mod options than the integral (XOR) option.

7. Final casework mods included a new top-mounting panel for all the new controls, a 1/4-inch jack output, and cherry hardwood side panels.

I'm well pleased with the results - enjoy!

I've finally got my computer fan working with the versatile Koma Field Kit, so here's a little proof of concept test using two electromagnetic pickups to capture plenty of stereo movement, by placing them in different positions on the fan. LFO output to DC Interface CV input. No FX added - recorded straight out of the Field Kit. Love these rhythms!

All these sounds have been captured by by Steampunk-customized Lite2Sound kit, by pointing it at flickering objects. They are in effect light signatures, and a great way to explore another dimension in sound.

The Rustacean was created from found objects, scavenged from seaside rock pools or rescued from rivers. Despite being deeply corroded, covered in verdigris, or tainted by rust, each part contributed its own unique sonic contribution to this steampunk windchime.

I recently bought one of the inexpensive Buddha Machine II boxes designed by the Beijing-based music duo of Christiaan Virant and Zhang Jian. This plays your choice of nine audio loops, each averaging about 30 seconds long, and repeated listening to these carefully chosen musical snippets can be incredibly relaxing, eventually becoming almost meditational.

I decided to extend both its musical possibilities and at the same time giving it a total makeover. The first step was some 'circuit-bending' (creative modification of the existing circuitry to add extra controls and sound options).

I then set about creating a new polished wood and brass enclosure for it, inspired by my current fascination with Steampunk (Victorian Science Fiction). It's now far more versatile as a loop player, as well as offering a raft of wicked distortion effects for incoming audio!

This is a short snippet from an upcoming release named 'Truning 495' that I rendered using standard Reaper summing for comparison.

MW Digital  Summing -2dB

This is a short snippet from an upcoming release named 'Truning 495' that I rendered using Airwindows PurestConsole (Channel & Buss versions) throughout. It's a subtle difference, but to my ears PurestConsole adds glue and spacial depth to mixes, and a sense of space around each sound that aids separation, along with extra clarity and detail in a quite remarkable way.

MW Console5 Summing -2dB

This is a short snippet from an upcoming release named 'Truning 495' that I rendered using the very latest Airwindows Console6 (Channel & Buss versions) throughout. It's once again a subtle difference, but Console6 is rather more aggressive than the Console5 variants, especially at this high -2dB level of buss peaks, which gives it a slightly 'crunchy' feel.

It's once again a subtle difference, but Console6 is rather more aggressive than the Console5 variants, but at my recommended -6dBFS level of buss peaks it offers a very clear 3D dimensionality with an enhanced top end.
