Synthesis 101: Synth Bass
Be aware that the Filter Envelope and Amplier Envelope work in
conjunction, with the Filter Envelope controlling how the lter opens and
closes and the Amplier Envelope controlling the overall volume shape.
To learn more about the Amplier Envelope, see page 42.
5. The Filter Envelope’s release parameter acts in conjunction with the
Amplier Envelope. In other words, you can’t hear a long release on
the lter envelope if the amplier envelope is short! So to hear the lter
envelope’s release parameter in action, rst set the Amp Envelope’s
release value to 75.
6. Now repeatedly strike a note on the keyboard as you turn the Filter
Envelope’s
release knob clockwise and counterclockwise. Notice how
the note fades out faster or slower as you change the release value.
Using Unison
You can use Unison to thicken the synth bass sound even more. When
unison is on, the Prophet X acts like a monophonic synthesizer — only
one note can be played at a time. However, that single note can be
powered by as many as 8 voices, depending on how many you choose
to stack together. (You can stack up to 16 voices if you are in 16-voice
mode.)
To use Unison:
1. Press the unison button on the front panel.
2. Repeatedly strike a note on the keyboard as you use Soft Knob 2
(
mode) to choose the number of voices to stack. The more voices you
stack, the denser the sound.
3. To detune the oscillators while in unison, use Soft Knob 3 (
detune) to
set the amount of detuning between voices.
Now you know how to create a simple synth bass program using the
most essential synthesizer components of the Prophet X: the oscillators,
the lter, and the envelopes. Using just these three things you can create
an enormous variety of sounds. Keep experimenting with them and if
you like what you’ve created, save the programs in one of the user banks.
(See “Saving a Program” on page 7.)
