Filter
BP filter 60-80 with high resonance settings gives good results.
8.4. Hihat
Oscillator
For hihats a complex, metallic noise spectrum is needed. Just use the 3 oscillators with high
frequencies and modulation amounts to get a spectrum you like. Sometimes a simple white noise
oscillator can give nice hats, too.
Amplitude Envelope
For hihats you have to set 2 decay times. One for the closed and one for the open hihat. Both are
quite short, but the open hihat decay should be longer than the closed. Use a very exponential slope
below 10 for hat sounds.
Filter
Use a highpass filter to remove all low frequencies. A high frequency around 120 is used.
8.5. Cymbal ride
Cymbals are similar to hats. The difference comes from the envelope and filter settings.
Oscillator
The oscillator settings can be similar to those of the hihat sound.
Amplitude Envelope
The only real difference to the hihat envelope is the decay time. We also use a strong exponential
slope, but a much longer decay is needed. It is also recommended to lower the volume of the voice
otherwise the cymbal sound may be too loud.
Filter
A bandpass filter with high resonance settings and a frequency above 110 gives good results.
LFO
The cymbal sounds really benefits from a LFO modulation the filter frequency. Use a low
modulation frequency and a sine wave with a gentle modulation depth so the different strikes won't
sound exactly the same and the frequency spectrum of the sound changes a little bit over time.
