The DR-03 Hi-Hats / Metal is the third module in the DR
series dedicated to analog drum synthesis. It is designed to
synthesize hi-hats and metal percussion like cowbells or
cymbals and even FX. Three different voices are available at
the same time Closed Hi-hat, Open Hi-hat and Metal plus a
Hihat mixed output .
Hi-Hats
To synthesize a Hi-Hat there is a key element that de nes
the nal result, the primary sound used to create it. The
DR-03 has three possible sound sources , a white noise
generator, a mix of six square wave oscillators and a mix of
ring modulated square wave oscillators. These three sound
sources, together with the VC Band Pass lter and the Low
Pass Filter allow the DR-03 to create a wide range of hi-hat
sounds.
Another interesting feature is that the Open Hi-hat decay
time is voltage controlled and it can be triggered indepen-
dently or conditioned to the Closed Hi-hat.
Metal
The Metal sound is created using two ring modulated
square wave oscillators and a VC Band Pass Filter. The
frequency of one oscillator can be manually controlled and
the other one has a xed frequency. The variable oscillator
can modulate the cutoff of the BPF to create metallic FM
sounds.
