Use
The trigger input has a range of about 5 to 12V. A trigger or gate signal of at least 5V will trigger the sound. A larger
trigger pulse will increase the level of the sound (accent the notes). When the accent socket is used, the trigger input
socket only triggers the sound and the level of the sound is controlled by the voltage of the CV at the accent socket.
The accent voltage can be from another trigger pulse generator, or from an LFO or Envelope. When using for example
an LFO, you can have the level changing with the LFO sweep.
The Tune CV input can be used to alter the tuning with any voltage. E.g. use LFO for slow pitch sweeps. Using audio
or any other high frequency signals to modulate tuning allows wild cross-modulated drum sounds to be produced. This
sort of modulation of pitch provides an extreme range of sounds to be produced, aside from the standard TR909 style
snare.
The trigger LED will light each time a trigger pulse is received.
Note; when the HPF control is set very high, some noise may low level hiss through. This is because the HPF is
being set far beyond the range originally intended. We have allowed the range to be extended in this way to allow a
much wider range of sounds to be produced. Remeber, the original 909 sound never allowed you to manually adjust
the HPF cut-off!
Controls
Tune Tunes the two oscillator ‘tone’ sounds.
Tone Sets the amount of noise. Higher setting increases the hold and decay time of the noise.
HPF Sets the cut-off level of the filter on the noise.
Snappy Sets the noise level.
Level
Sets output level.

Introduction
The SD99 is an accurate replica of the TR909 snare drum sound. The
module is entirely discrete analogue circuitry, based as closely as possible
on the original.
The SD99 can produce more than just snare drum
sounds...
