Claves and Woodblock
Claves and woodblock sounds are also very similar. They both consist of very short sine
or triangle waveforms. A woodblock is lower in frequency, and you can add the second
oscillator to produce a different frequency. Claves should be made with only one sine
oscillator and a very short envelope.
TR-808 Cowbell
You are waiting for this one, aren't you? The TR-808 Cowbell is made of two square
oscillators, one oscillating at 540Hz, the other oscillating at 800Hz. The attack phase of
the envelope is emphasized heavily to create the strong click. Afterwards, the summed
signal is sent through a band pass filter and an envelope that stops abruptly.
A funny side note: on the TR-808, the square oscillators were the same that were used
for the cymbal and hi-hat sounds. However, those sounds used a cluster of six detuned
square oscillators with different band pass and high pass filter settings.
Concluding Remarks
We hope that this manual has helped you to familiarize yourself with the interesting
world of analog drum sound synthesis.
Since 1989, Waldorf has cultivated a tradition of synthesizers, and continues to deve-
lop a wide range of different units based on powerful sound generation systems. If you
