Re: [Bluemusic-users] CMdrum-01

[Mark V. P. <Mar...@te...>]

The article doesn't mention how the envelopes of each frequency varies 
over time, or what the ratios of the amplitudes for different 
frequencies are, so it is not easy to get it right. The article doesn't 
mention noise or bandpass filtering, neither strike velocity. To get it 
better I would stick to simple sines, not the other waveforms, have more 
frequencies (the article mentions up to 12) and have amplitudes for each 
frequency. Or maybe simply making the amplitude inversely proportional 
to the frequency (or the square of the frequency) is enough, that often 
makes it sound more realistic.
