The idea behind Extreme DrumSynth is that most percussion sounds can be modelled using a combination of resonant frequencies and noise. In general you will use the oscillator section to model the resonant frequencies.

For drum sounds:

You will typically use just a few layers of simple oscillators with a small amount of modulation.

For cymbal sounds:

you will wnat to use several layers of the more complex metal oscillators combined with modulation to create several inharmonic modes.

Modulation

Very few real life sounds are static, so to create more interesting and realistic sounds it is important to add envelopes and lfos to several of the parameters. Try experimenting with all of the parameters to get an idea of which ones have the most impact.

The attack and release settings in the master section affects the speed of the envelopes and can have a bit effect on the sound. Try varying these settings to make all of the envelopes faster or slower. These settings also work well if you add velocity control.

Many sounds are brighter when they are hit harder. You can model this by adding velocity control to the filter widths, or oscillator balance.

You can add random control to parameters so that every hit sounds a little bit different. The filter frequencies work well for this.

The compressor can be used to adjust the overall punchiness of the sound.

Many synthetic drum sounds can be created using a simple single layer waveform and sweeping the oscillator frequency from a high frequency to a low frequency.

Try using an lfo to modulate its own rate. It will distort the shape of the lfo waveform.

Use envelopes on the lfo depth to make lfos that fade in or out.
