1 Introduction
Ultra Analog VA is a virtual analog synthesizer that combines into a modern instrument features
of the legendary vintage synthesizers. Ultra Analog VA generates sound by simulating the dif-
ferent 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. Ultra
Analog VA therefore 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 AAS product. We sincerely hope that this product will bring you inspiration,
pleasure and fulfill your creative needs.
1.1 System Requirements
The following minimum computer configuration is necessary to run Ultra Analog VA:
Mac OS :
• Mac OS X 10.5 or later
• Intel Core processor or later
• 512 MB of RAM
• 70 MB of free hard drive space
• 1024 x 768 screen resolution
• Built-in audio interface
Windows :
• Windows XP SP2 32-bit or Windows Vista/7 32-bit/64-bit
• Intel Core or equivalent processor
• 512 MB of RAM
• 70 MB of free hard drive space
• 1024 x 768 screen resolution
• Windows-compatible audio interface
• Windows-compatible MIDI interface/keyboard
Keep in mind that the computational power required by Ultra Analog VA depends on the num-
ber of voices of polyphony and the sampling rate used. These computer configurations will enable
you to play the factory sounds with a reasonable number of voices but performances will vary
depending on your specific computer configuration.
