808 Maracas
The 808 has an highly artificial and unrealistic emulation of a shaker/maraca. Read some notes about the 808 maracas here.
The sound is just filtered white noise. No cables are required for this patch.
1: Switch noise to ‘white.’
2: Pull down everything in the mixer except noise.
3: Switch the VCF to High-pass (HP4).
4: Ensure the envelope is not modulating the filter by setting VCF FM1 level to 0.
5: Set VCF Q level to 0.
6: Remove the low frequencies by raising the VCF frequency about 75% of the way up.
7: The 808 Maracas has a very short envelope (between 25 and 35ms). Set ENV-A to fast.
8: Refer to the waveform above. Unlike the other 808 sounds the Maracas doesn’t have a decay only envelope. It has an attack time that’s 3/4 as long as its decay time. Adjust the attack and decay times until you’re getting a soft “chik” sound.
