Just for interest, below is an mp3 snippet of MOTM Frequency Modulated
Synthesized HiHat, Cymbal, and Kettle Drum tests I was trying today. I was
trying to come with a way to get metalic noise like partials. What I came up
with was one oscillator generates a sawtooth output, but it is modulated with
a sine from a second oscillator which in turn it modulated by white noise.
Because I have 4 oscillators I was able to patch up two of these and tune
them to different frequencies. So the HiHat and Kettle Drum use two
metal/noise partials. I cheated on the cymbals and recorded a few of them at
different frequencies and then mixed them together for a fuller sound. The
Kettle Drum only sounds good on one note, and being monophonic forget about a
drum roll. If I need another note, I need to resynthesize the patch for
another pitch, but I did drop one hit down digitally. Kettle Drum needs to
be heard loud with good bass.
