- Two of several modules are included on this disk. They are fully functional
- with the exception of the SAVE functions which has been replaced with ABOUT SYNTHIA.
- The release version saves instruments in

- Brief description of SYNTHIA:
- .UNDERLINEOFF
-
- .in +3
- Synthia is a high performance synthesizer. It provides a musician with a means
- of creating musical instruments to a precision which is difficult to match with
- hardware based synthesizers. It uses the IFF format for compatibility with other
- musical and sound effects products (digitizers, video managers etc.).
- Synthia was not based on an existing synthesizer. Instead Synthia attempts to
- synthesize real instruments. Since Synthia uses a computer, much more interaction
- is possible than with a traditional synthesizer. This allows much greater precision
- to be used when creating instruments.
- State of the art algorithms are implemented in Synthia. This allows a breakdown
- of Synthia into different modules, each with its own strengths and weaknesses.
- The modules implemented at this time are:
- .in +3
-
- 1.
- .RED
- Synthia
- .BLACK
- - a traditional subtractive synthesis package. A waveform is repeated
- through the sound and modified with filtering, frequency, phase, amplitude
- modulation, and other effects. Great for most 'traditionally synthesized' instruments.
-
- 2.
- .RED
- Additive
- .BLACK
- - an additive synthesis package. Works by mixing a changing amount
- of the first 16 harmonics of a waveform, usually a sine wave. Can be used to
- create just about any type of sound possible.
- .RED
- This module is included in the
- demo.
- .BLACK
-
- 3.
- .RED
- Interpolative
- .BLACK
- - interpolates between 8 waveforms over the duration of the sound.
- Not as accurate as Additive but is excellent for most percussive musical sounds
- such as the piano. It introduces some imperfection which sounds very nice in
- some circumstances.
-
- 4.
- .RED
- String
- .BLACK
- - our pride and joy. Does guitars, basses, and about any type of plucked
- string possible. It has very little overhead considering it generates one of
- the more difficult types of instruments to simulate. It uses a new algorithm
- to accomplish this.
- .RED
- This module is included in the demo.
- .BLACK
-
- 5.
- .RED
- Percussion
- .BLACK
- - simulates several families of percussive instruments. Uses a
- new algorithm to generate more realistic percussion.
-
- .in -3
- Synthia uses a waveform editor to design waveforms, envelopes and tables for
- various parameters. It features harmonic, Chebyshev polynomial, linear, and spline
- generation. Several waveforms are also available. The user may also draw a waveform
- if desired.
-
-
- Synthia also has several modules for modifying an existing sound. The modules
- are:
- .in +3
-
- 1.
- .RED
- Filter
- .BLACK
- - for wow effects etc. Supports highpass, lowpass, bandpass, and band
- limit filtering.
-
- 2.
- .RED
- Amplifier
- .BLACK
- - for making the sound louder or softer. It is a clipping amplifier
- so it can generate distortion effects as well.
-
- 3.
- .RED
- Amplitude Modulation
- .BLACK
- - like an ADSR generator on most synthesizers, but uses
- a Synthia envelope which allows 256 point precision envelopes.
-
- 4.
- .RED
- Reverb
- .BLACK
- - true reverb. This module was designed knowing that an echoed sound
- is NOT identical to the original. It is modified with a frequency dependent phase
- shift to resemble true echoes. Also has a filter for simulating concert hall
- effects. Feedback and level are independent of each other.
-
- 5.
- .RED
- Flang
- .BLACK
- - called Phasing on some systems . This is a modulated phase shift (or
- comb filter) effect.
-
- 6.
- .RED
- Non-Linear Distortion
- .BLACK
- - called Wave Shaping or Non Linear Processing on other
- systems. This changes the harmonic content of a sound based on its amplitude
- etc. Trumpets, flutes, and many other instruments can be simulated by amplitude
- modulating a sine wave and passing it through this module. Fuzz effects can also
- be created with this module. Chebyshev polynomials provided in the waveform editor
- provide control over this module.
-
- .in -3
- A couple more modules are planned for the release version.

- The following products have been tested with Synthia generated instruments:
-
- .RED
- .nf
- Deluxe Music Instant Music Deluxe Video
- Sonix Music Studio (with IFF conversion)
- Soundscape Pro Midi Studio
- .fi
- .BLACK
- Synthia should be compatible with many others.
-
- Synthia also allows modification of digitized sounds, so it is a perfect companion
- to any hardware product that create sounds.
