.: Introduction
At the beginning of the 80s, a new bass synth appeared on the market. Aimed at bass-guitarists, it featured an in-built sequencer with slides and accents. Only about a decade later did it become one of the most popular instruments in certain styles of acid, techno, house and trance music. Since that, numerous copies and software and hardware emulations have been born, which all try to grasp the character of this wonderful synth. We did our best to reincarnate this instrument as an authentic-sounding, convenient and easy-to-use VSTi plugin. Countless hours were spent on analysis and measurements, with the goal of making the most-authentic sounding emulation. As a result of the research, SilverBox was born, 25 years after the creation of the machine.

.: Overview
What is SilverBox?

SilverBox is an authentic digital emulation of the world's most renowned and famous analog bass line machine. It's square oscillator accurately models the oscillator of this 80s analog beast, giving a spectrally different square wave for different notes. The in-built sequencer has the traditional behaviour with accents and slides. The accent circuit is probably the most difficult to faithfully reproduce virtually, and most other emulations simply fail to reproduce the typical barking sound.

Accent and filter

Most emphasis was on creating the best accent emulation possible, because no virtual plugin fulfilled our expectations. The same applies to the filter - most other emulators don't reproduce the typical resonance character thoroughout the entire frequency range at all.

Why is it different?

The most striking difference with SilverBox and most other emulators (besides sound) is the ease of use. You see the entire pattern instantly, no need to cycle through steps to see what's going on in the pattern. With dedicated rows for gate, up, down, accent and slide, you can alter patterns easily and quickly. The piano roll gives you an overview of the melody in a familiar way. The pattern functions give you an intuitive way of quickly and easily delete, shift, or randomize rows independently. The random functions allow you to set a random probability for each row, which allows you to create many similar random patterns at a click of button. Unlike the original which is difficult to program, SilverBox is really easy and fun to use.

"It is one of the most user friendly instruments these days and this makes SilverBox proudly stand out amongst others."

Alexander Arsov, Wusik Magazine

Sound quality

The second most important aspect was the sound quality. SilverBox uses oversampling where necessary, to minimize annoying high-frequency aliasing artifacts at internal distortion, typical with virtual instruments. With its sophisticated 16x oversampled in-built distortion engine, SilverBox can drive your basslines with an amazing +80 dB into four types of saturation, with nearly no digital aliasing artifacts. That means, if your host runs at 44.1 kHz, then SilverBox processes sound internally at 705.6 kHz!

"Silverbox sounds amazingly good. It definitely has the 303 sound and it doesn't sound artificial like some virtual instruments do."

Alexander Arsov, Wusik Magazine

Efficiency

Despite the extreme oversampling, SilverBox runs lightning fast on your SSE-enabled processor. Designed to utilize modern CPUs' efficient instruction sets, SilverBox processes 4 samples at once! This gives you a lightweight plug-in which allows you more instances, and leaves you more horsepower for the rest.

Extras
In addition to the standard features, SilverBox has a bunch of extras as well. There are additional four unique filter modes with bandpass, highpass and peak responses, at the same time retaining the typical resonance character. The MIDI out feature allows you to drive another software of hardware synth with the SilverBox internal sequencer. And the noise feature adds some hiss, to make the sound less digital and sterile.

.: Demo
The demo version has the following restrictions:
  • The sound drops out every 45 seconds.
  • The number of presets is limited to 16.

Notes:

  • The installer doesn't create any additional files, folders or registry entries; just copies the files to the location you specified.
  • SilverBox doesn't give any sound until it receives MIDI input from the VST host, so you need to add some notes in your sequncer or press a key on your MIDI keyboard in order to hear sound.
