Long Version for Those Who Like Explanations
Here's a more detailed version that provides insight into the process.
You'll start with the Basic Program, then learn how to choose an appro-
priate oscillator waveshape, how to use the filter, how to use the enve-
lopes, and how to use Unison to fatten things up.
In the Basic Program, only Oscillator 1 is audible. Its waveshape is set to
sawtooth and its level is 127 in the
and Instrument 1 and Instrument 2 don't have an instrument selected.)

Each of the waveforms have their own unique sound:
• The sawtooth waveform is a good starting point for sounds because it
has plenty of harmonics. This gives you a lot to work with in terms of a
raw sound that you can filter and modulate.
• The Pulse (square) wave is a good starting point, too, but sounds differ-
ent than the sawtooth, because of its different harmonic content. The
sawtooth has even-numbered harmonics and the square wave has odd-
numbered harmonics. (Google this if you want to learn more.)
• The sine wave has no harmonics. It's useful used alone for its pure
tone, or in combination with another oscillator or sample(s) to reinforce
the fundamental pitch of a sound and add weight.
• The super sawtooth is a stacked version of the sawtooth and sounds
very thick when you use the
brass, strings, and dance music sounds.
