• Troubleshooting
A common source of confusion when working with the filter envelope
is that the Attack or Release parameter might not seem to be working
correctly. Referring to the diagram below which shows the Planet
Phatt signal flow, you will notice that the DCA comes after the Filter.
The DCA controls the final volume of the sound, so if the filter's
release is longer than the release for the DCA, you won't hear it, be-
cause the DCA has already shut off the sound.

This is just an example of why troubleshooting is important. If you are
not getting the expected result, try to analyze the situation. There will
be many times when you will have to stop for a minute and think,
"What am I trying to do and why isn't it working?" When this hap-
pens (and it will), don't panic. Troubleshooting is a normal part of the
synthesis process. Simply examine the various parameters and try to
be as analytical as possible as you solve the problem. Usually the
solution will be simple. (The filter is already wide open and can't open
any more.) Learning to play an instrument takes... Practice.
You're probably getting the general idea by now. Remember not to
change presets or the preset will return to normal. If you want to save
your creation, select the last screen in the Edit menu and select a
destination preset location for your masterpiece, then press Enter.
Practice Modulating
• Try modulating the pitch with the Aux. Envelope generator
• Use velocity to modulate the Aux Envelope Amount or the filter
Fc. (Key/Vel. screen). This will brighten the sound as you play
harder.
• Program the LFO to modulate filter Fc and volume (Realtime
modulation screen).
• Modulate the LFO with the other LFO, with velocity, and with the
modulation wheel.
• Think of ten different modulation routings, then try them out. The
key to learning about Planet Phatt is to experiment.
