The OSC section contains the parameters for setting the root key and fine tuning.

Everything OK? Congratulations, you've just built your first EWS instrument.
Now you can start tinkering with the synthesizer parameters...
Setting parameters
The following is an example of how we can expand our instrument with a simple
LFO filter modulation.
•
First, prepare the filter for an easily detectable modulation. In other words, a
low filter frequency at high resonance. So, let's set the following values in the
FILTER section: Cutoff = 10, Q = 100.
•
Now let's set the LFO which will modulate the filter to a slow speed. Set the
following value in the LFO 2 section: Frequency = 4.
•
As a third point, we have to inform the filter that it will be modulated by the
LFO. Click on the active button located to the left of the LFO 2 amt
parameter.
•
When you now hit a key, you will clearly hear how the LFO modulates the
filter. You can now experiment with the other settings. Change the LFO speed
or LFO waveform, or test the interaction of the filter frequency and resonance.
