Dave Smith DSM02 Character Module Review
Written by Tom Lewis
The Character Characteristics
This 14HP module houses a powerful digital effects processor, DSM02 provides the five high quality algorithms from the Pro2 and Prophet 12 synthesizers - they are; Girth, Air, Decimate, Hack and Drive. These effects are some of the key building blocks that make the P12 and Pro2 sound so good. Now you can get these superb effects with modular connectivity and CV capabilities. In keeping with the DSM01 filters colour scheme, DSI have produced a stylish black faceplate with soft touch knobs, encrusted with audio I/O and CV connectivity. Dual mono audio inputs and outputs provide flexible routing and integration. 5 CV inputs allow hands of modulation control of each of the effects, though only a single dial for each effect, they can, when blended together create some very interesting effects and timbres. The knobs feel rock solid and the module itself has a reassuring weighty feel.In practice
The DSM02 is a really simple way to inject some flavour and instant versatility into your signal path and doesn’t require much work for the reward. We decided to test exactly what we could get out of it. To test the Character module we decided to pair it up with our favourite mono modular the Intellijel Atlantis, and a new go in our system; the Doepfer A-143-4 quad LFO / VCO. The Intellijel should give us smooth analogue waveforms that will work well with processing and the A-143-9 can provide a wide variety of modulation signals that vary from LFO to VCO rates, so we should get some interesting results. Our initial test was simple, run a simple, open square wave into the character and began to tweak the front panel controls to see what kind of scope we’ve got. Let's talk about each of the effects and what they offer independently; Girth - this is a particular useful tool for fattening up thinner oscillators and sound sources, essentially it's a low end frequency enhancer which adds substantial beef and body, it sounds absolutely incredible when working with a PWM pulse wave and under subtle modulation control. You get these big swooshing, pulsating moving timbres that really add an extra dimension and diversity to your patch. Air - the antithesis of girth, a high end frequency enhancer which found little use at first as its effects are quite subtle. But then we started using it as a mix tool for separating out harmonics in a muddier sound, there it shines and I can totally see it making an impact in a more production based system. Not one for modulation control in my opinion, but it's a very useful mix tool. Decimate - probably the sound from this module, not only does the name fill me with pleasure; but the sound and effect it has is simply delightful. It's a really over harsh bit crusher, that down samples incoming audio. It can add subtle grit or can effortlessly move into downright filth. This particular section produces some very interesting results when externally modulated, we used a sum signal from the A-143-4, a very slow square from LFO 1 and a sum of a triangle wave modulating the rate of another square. This combo provided some of the most interesting bit crushed sounds I've in modular; odd time measures combined with evolving LFO rates. Totally awesome.
