Sound design ideas you might not have considered

Synths are now such an integral part of the DAW experience that it's easy to forget that they exist as individual tools with their own distinct feature sets.
This being the case, there's a good chance that you're currently blissfully unaware of some of the clever things that your synths can do, and of what you can do with your synths.
What's more, it's worth remembering that there are times when it's best not to use a synth at all.
Read on to find out more...
1. Find the metal
Your sampler might be an obvious source of metallic sounds, such as cymbals and gongs, but don't overlook that trusty analogue synth. Many subtractive instruments offer frequency, amplitude and ring modulation. These can provide a wealth of twisted metal textures that can be used for everything from tinny hi-hats to clangorous bells.
2. Synth as effect
Like many soft synths, some virtual Minimoogs can act as effects plug-ins, too, so you can route any signal through your favourite filters for some sweetening. Consider plumbing your sampler or other synth patches through it.

3. Build your own…
So, what if you've searched through vast numbers of instruments and still haven't found the sound you've got in your head? Maybe it's time to create your own dream synth using one of the many modular environments, such as Reaktor, SynthEdit or SynthMaker. These programs enable you to string together various components. Some of them will even export the result as a plug-in to be used in your DAW.
4. … Then keep building
Sample-based synthesizers can be powerful allies in the search for the perfect sound, but many of them are hobbled by being tied to a collection of waveforms over which you have no control. Free yourself from the factory by creating your own synth, using a sampler like Kontakt or HALion, and loading it with your own selection of waveforms. We're not just talking about real instruments (though those are good, too), but sampled and looped waveforms of any description. Use a signal generator like the ones built into Audacity and Sound Forge to create waveforms, or whip some up with an additive instrument and then record them without any filtering or modulation. These can provide fantastic fodder for you soft samplers.
5. Pilfer the frequencies
You can also use the above technique to 'steal' the harmonic content of an acoustic or electric instrument and then reshape it into something that has the character of the original, but that's entirely your own. Record only the sustained, steady-state portion of each note and create short, looped waveforms from them. You can then apply envelopes and modulation as you see fit in the software of your choice.

Big thanks to all the CM readers who've been in touch to tell us how useful...
Now here’s a brilliant idea. Rather than gracefully retiring his trusty Akai MPC4000...
