-
- This is a demo of 33mSYNTHIA 31m, a high performance synthesizer available
- soon from: 1m

- 0m
-
- 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 33mIFF 31mformat. 4m

- OPERATING INSTRUCTIONS FOR SYNTHIA DEMO
-
- 0m
- To operate the Synthia disk:
-
- 33m
-
- 1. 31mLoad Kickstart 1.2. (1.1 should work but is untested) 33m
-
- 2. 31mPlace the 33mSynthia 31mdisk in df0:. It will boot to 33mWorkbench.
- 33m
-
- 3. 31mOpen 33mSynthia 31m's disk icon. 33m
-
- 4. 31mSelect the 33mString 31micon. 33m
-
- 5. 31mWhen the 33mPlucked String 31mwindow appears, select the 33mDO SOUND
- 31mgadget. When the BUSY pointer changes back to the standard pointer,
- the AMIGA keyboard can be used to play the instrument or the KEYBOARD
- gadget can be selected.
-
- Various parameters can be changed by using the Synthia gadgets. Use
- the DO SOUND gadget to implement the parameter changes that have been
- made on the main screen and the SPECIAL EFFECTS screens.
-
- 1mNOTE: 0mDefaults are set for the Plucked String design.
-
- 1mNOTE: 0mREPEAT FINE and REPEAT COURSE change the repeats without selecting
- DO SOUND.
-
- 1mNOTE: 0mThe other module (ADDITIVE) in Synthia has defaults set and can be
- selected. (The defaults for the SPECIAL EFFECTS are set for the Plucked
- String instrument default.) 0m

- 4mBrief description of SYNTHIA: 0m
-
-
- 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:
-
-
- 1. 33mSynthia 31m- 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. 33mAdditive 31m- 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. 33mThis module is included in the demo. 31m
-
-
- 3. 33mInterpolative 31m- 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. 33mString 31m- 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.
- 33mThis module is included in the demo. 31m
-
-
- 5. 33mPercussion 31m- simulates several families of percussive
- instruments. Uses a new algorithm to generate more realistic
- percussion.
-
-
- 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:
-
-
- 1. 33mFilter 31m- for wow effects etc. Supports highpass, lowpass,
- bandpass, and band limit filtering.
-
-
- 2. 33mAmplifier 31m- for making the sound louder or softer. It is a
- clipping amplifier so it can generate distortion effects as well.
-
-
- 3. 33mAmplitude Modulation 31m- like an ADSR generator on most
- synthesizers, but uses a Synthia envelope which allows 256 point
- precision envelopes.
-
-
- 4. 33mReverb 31m- 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. 33mFlang 31m- called Phasing on some systems . This is a modulated
- phase shift (or comb filter) effect.
-
-
- 6. 33mNon-Linear Distortion 31m- 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.
-
-
- A couple more modules are planned for the release version.

-
- The following products have been tested with Synthia generated
- instruments:
-
- 33m
-
- Deluxe Music Instant Music Deluxe Video
-
- Sonix Music Studio (with IFF conversion)
-
- Soundscape Pro Midi Studio
- 31m
-
- 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.
