1 Introduction
The Ultra Analog VA is a virtual analog synthesizer. With this product, we have not attempted
to emulate a specific vintage analog synthesizer but rather to combine into a modern instrument,
different features of legendary vintage synthesizers. The Ultra Analog VA generates sound by
simulating the different components of the synthesizer through physical modeling. This technology
uses the laws of physics to reproduce how an object or system produces sound. In the case of Ultra
Analog VA, mathematical equations describing how analog circuits function are solved in real-
time. The Ultra Analog uses no sampling or wavetable, it just calculates the sound as you play in
accordance with the controls it receives. This sound synthesis method ensures unmatched sound
quality, realism, warmth and playing dynamics.
Before discussing the synthesizer in more detail, we would like to take this opportunity to thank
you for choosing an Applied Acoustics Systems product. We sincerely hope that this product will
bring you inspiration, pleasure and fulfill your creative needs.
1.1 System requirements
The following computer configuration is necessary to run the Ultra Analog VA:
Mac OS :
• Mac OSX 10.2 (Jaguar) or later.
• G4 733 MHz Processor
• 256 MB RAM
• 1024 x 768 or higher screen resolution
• MIDI Keyboard (recommended)
• Ethernet Port
• Quicktime 4.0 or later
Windows :
• Windows 98SE/ME/2000/XP
• PIII 800 MHz
• 128 MB RAM
• 1024 x 768 or higher screen resolution
• DirectX or ASIO supported sound card
• MIDI Keyboard (recommended)
Keep in mind that the computational power required by the Ultra Analog VA depends on the
number of voices of polyphony and the sampling rate used. These computer configurations will
enable you to play the factory presets with a reasonable number of voices.
