The SD909 comes equipped with two modulated triangle oscillators and a binary noise source. The pitch of the VCOs can be altered via a potentiometer and a control voltage input. For editing the noise generator, there are volume (Snappy) and decay (Tone) controls. Furthermore, it is possible to adjust the clock which drives the binary circuit via a potentiometer and a CV input plus attenuator. Low values lead to metallic results. The main output features a level knob with distortion capabilities. Additionally, there is an individual output for the noise generator.
The SD909 is played via gate / trigger and accent connectors. As long as there isn’t a cable plugged into the accent socket, both inputs are normalized. A trigger button allows users to play snare sounds directly at the module’s front panel.
The SD909 is compatible with Tiptop Audio’s MIXZ MixBus.
