1 Introduction

The Ultra Analog is a virtual analog synthesizer. With this product, we have not attempted to emu-

late a speciﬁc vintage analog synthesizer but rather to combine into a modern instrument, different

features of legendary vintage synthesizers. The Ultra Analog 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,

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 to

the controls it receives. This sound synthesis method ensures unmatched sound quality, realism,

warmth and playing dynamics.

Before discussing the synthesizer in more details, 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:

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/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 depends on the num-

ber 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. Although it is not absolutely

necessary, it is strongly recommended to play the Ultra Analog with a MIDI keyboard or controller.
