/* WONDERSOUND 1.4 may be freely redistributed by all conceivable means */
Wondersound is an additive harmonic instrument design tool with a separate
envelope design window and 16 relative harmonic strength and phase angle
controls. The top gadgets in the main window control the harmonic strengths;
the bottom gadgets, the phase angles.
The two large gadgets on the right control a frequency modulation process.
The left one, the multiple of the fundamental (integers from 1 to 16) for
the modulating wave's frequency and the right one, the amount of modulation.
The large gadget on the far right controls the frequency of the sound
during play.
The envelope gadgets are from left to right: attack-level, attack-time,
sustain1-level, sustain1-time, sustain2-level, sustain2-time and
release-level, and release-time.
/* Procedure */
When WONDERSOUND 1.4 first comes up, there is a request to WAIT so the
necessary tables can be computed. The envelope window then appears.
You must make an envelope before proceeding. Change some of the envelope
gadget positions and then select the close-window gadget to complete the
envelope creation process. This will return you to the harmonic and
phase control window. By selecting "ENVEL" from the menu you may return
to the envelope design window. Remember, selecting the close-window gadget
of the envelope design window is the last step in creating a new envelope.
The system uses an accumulative mixing process whereby each harmonic
computed is combined equally with the previous sound, allowing the
development of arbitrarily complex sounds. For this reason WONDERSOUND
is best used repetitively; changing the phase and harmonic strengths
slightly with each run and/or changing the envelope, thus simulating
the more chaotic evolution of a natural sound. Selecting "WAVIT" from
the menu activates the additive harmonic process.
The display stacks every eight points vertically so sonic regularities
may be visually recognized. Try creating an instrument without changing
the phase angles. This should result in a more ordered mapping and
thus a less subtle musical result.
There is a string gadget on the top left for naming instruments. The
default name is "IO.inst." Selecting "SAVIT" from the menu saves the new
sound as an IFF 8SVX 5 octave instrument.
I realize there can be a problem with trailing sounds. When you mix new
envelopes, phase angles, and harmonic strengths, the results are rather
unpredictable. If the release-level for the next envelope is raised far
above zero at the problem point, the mixing process will often cancel out
a trail. Each realization of harmonics and phase angles is mixed with
the previous realization, so raising the envelope at a problem point
can often cancel out unwanted dips in the generated sound's envelope.
Sorry no loop points, maybe someday...
