SOUND ON SOUND
Waldorf's Q keyboard workstation definitely suffered by being released to the public before its operating system was completely finished or bug-free. Gordon Reid takes advantage of the release of the new Q Rack module to revisit the operating system and see how it's come on...
The Roland Promars helped to usher in a new era of microprocessor-controlled analogue synthesizer, but has subsequently been all but forgotten. Gordon Reid remembers the world's only 'Compuphonic' monosynth.
Last month, we examined the frankly scary maths allowing you to predict the audible effects of Frequency Modulation. This time, although the maths gets even tougher, Gordon Reid relates the theory to the practical implementation of FM synthesis on Yamaha's digital synths, as well as modular and non-modular analogues.
Gordon Reid checks out a compact filter module that won't break the bank.
As explained last month, audio-frequency modulation of the amplitude of a signal can be a powerful synthesis tool. The possibilities expand still further when we consider what happens when you use one audio-frequency signal to modulate the frequency of another...
Analogue Solutions' diminutive Minimodular contains all the necessaries to make up a miniature patchable synth. Gordon Reid arches an eyebrow at this innovative and compact sound source.
In Part 1, author Gordon Reid told us how he found one of the world's rarest synthesizers in Australia, and of the trouble he went to to get it home. In Part 2, he explains what it is about the Yamaha GX1 that made it all worthwhile...

Last time, we examined the concept of modulation at low frequencies. This month, we speed things up a bit. The result is not just faster versions of the same modulation effects, but a new type of synthesis...
The long-awaited Omega 8 promises much, even if its feature-set is not yet complete. Gordon Reid takes a first look...

In this month's instalment of his series on the basics of subtractive synthesis, Gordon Reid considers the magic ingredient that makes all the other elements sound interesting...
