Thank you for purchasing the RED Sound DARKSTAR XP2 8-voice polyphonic synthesizer.

The Analogue Synthesiser, mainstay of Seventies' and Eighties' music, is back, reinvented in a new, more reliable
and flexible form. Physical modelling via powerful DSPs (Digital Signal Processors) allow all the warmth and control
of the synthesizers of yesteryear without the problems of unstable tuning and unrepeatable sounds, and with
modern benefits like realtime control and multitimbral access.

Welcome to DARKSTAR XP2, an 8-voice polyphonic synthesiser with all the highlights of the analogue tradition,
Pulse Width Modulation, Ring Mod, Resonant Filtering and ADSR Enveloping, combined with all the advantages of
modern MIDI instruments like rock-solid tuning, perfect program recall, velocity response and 5 different timbres
simultaneously available.

So whether your aim is to recreate 'classic' timbres like 70's Disco Bassline / Screaming PWM Lead, chart new
sonic territory with realtime joystick manipulation of filter frequency and resonance, or even combine both
approaches in the same MIDI sequence, DARKSTAR XP2 is the perfect tool for you.

In the future, DARKSTAR XP2's capabilities will grow thanks to the ability to install other EPROM-based DSP
algorithms. This will allow you to convert DARKSTAR XP2 into many different products such as a vocoder or mono
synth.

But DARKSTAR XP2 already offers so much with its marriage of proven synthesis techniques and state-of-the-art
control. Now it's time to unlock the potential of analogue-style synthesis with modern control techniques in your
music.

Be creative!
