Synthesized Drum Sounds

Snare Drum Crack of the drum – a fast glissando of a square wave over multiple octaves. Make it so that you hear the gliss as a quick blip sound rather than hearing the gliss. This means it should be very short. The center frequency of the gliss should be about 600-800hz, so you probably want to gliss from over 1000 to below 400.

Metal Snares – WhiteNoise with a longer envelope than the crack sound above

Filter – Send both the Crack of the Drum and the WhiteNoise through a Low Pass Filter

Resonance of the drum shell – a sound about as long as the snare sound. This should be a sine wave oscillator at about 400hz, that drops about a semitone (25hz at 400) over the duration of the sound.

Add the filtered crack and snares to the resonance sound.

Bass Drum Crack of the drum – same as the snare, but lower the frequencies of the starting and end points of the gliss. Maybe make a gliss from 400 to 50. I feel like you might want to almost hear the glissing note with the bass drum

Resonance of the drum shell –This should be a sine wave oscillator at about 100hz, that drops about a semitone (25hz at 400) over the duration of the sound.

Add the two sounds together.

Hi-Hat

Crack of the drum – an even faster glissando of a square wave over multiple octaves. Make the center freq of the gliss to be about 2000hz, significantly higher than the snare drum, and make the gliss only about 2 octaves, so a quick gliss from 4000 to 1000hz should work.

Resonance - Modulate the frequency of a SinOsc by WhiteNoise. With each hit, vary the center frequency of the SinOsc and the index of modulation. Give the SinOsc a small gliss downward like in the snare and bass drum. Send this sound through a Resonz (resonant band pass) with a r

Envelope – a super short envelope will make a closed hi hat sound. A longer decay will make an open sound.

ASSIGNMENT 1) Make one of the drums above. You can go for “reality” or not, ie, if it sounds cool, that is all that matters. 2) Make another percussive sound that sounds however you want. Filters, noise, and envelopes go a long way. Keep it simple. I think you will be surprised at how musical things can be when kept simple.
