Retro Digital Sound
BitRate offers 4 main sound engines:
The CHIP engine contains 5 modules based on the sound chips used in video game consoles of the 8bit era. These modules are ideal for any musician interested in chiptune, or for adding a little retro-nostalgia to your tracks. |
IA-OP stands for Icebreaker Audio Operator, and is a 2 operator FM synthesis engine based loosely on the Yamaha FM chips used in PC soundcards and 16bit game consoles from the early 90s. The engine has two modes: Additive and Frequency Modulation; and a control set designed specifically for creating drum sounds. |
The SMP engine is a sampler with a twist. Based on toy keyboards from the late 80s, the SMP engine not only features 50 individual samples, but also a custom built sample Core Cell with “circuit bending” controls. |
And lastly, the Gl!tch modules. These are not based on any kind of specific synthesis style, but are more a result of DIY experiments with a harsh digital edge. Kind of like Atari Punk Consoles, but in software. |
Drum Machine Features
- Modulation:
Each of the 5 drums has its own sequencer channel, with two modulation sequences. The modulation sequences can be routed to virtually any sound parameter of the drum.
- Effects:
The sound can then be further sculpted by a per-channel EQ; mixed using the channel strip; then further processed using the master EQ, bus compression, and a speaker simulation effect.
- Routing:
You also have the option to route the individual drum channels through their own outputs to your soundcard or host DAW. In addition to this, there is an Aux Send channel available for creating a sub mix for external processing.
- Triggering:
If you don’t want to use the built-in sequencer, that’s ok, the drums can also be triggered via MIDI input.
Authenticity and Flexibility
| Although no single device was specifically emulated, the aim for the sound engines was to stay true to the selected synthesis styles. Volume envelopes, tuning characteristics, and many other small details were analysed and replicated. |
| BitRate offers, among other things, the most accurate chip-style synthesis available for Reaktor. A sample engine needed to be coded in core from scratch in order to accurately emulate the gritty pitch-shifting and circuit bending possibilities of late 80s keyboards. |
| The sound of BitRate may be accurate, but the features were designed to make the instrument easy to use, yet also flexible. The clunky interfaces, bad integration, lack of sync options, and hardware faults are no longer an issue – no need to blow on cartridges! |
