Improve implementation (sound and custom parameters) for 'Cymbals' (Midi notes: 49, 57, 52)

[lilyvanoekel]

Feature Description

Please improve these sounds:
49 Crash Cymbal 1
52 Chinese Cymbal
57 Crash Cymbal 2

They currently sound interesting, but maybe not very convincing as cymbals, also up to 3 parameters can be defined.

For guidance, please refer to the Improving a Sound guide.
