The 8raw8 Analog Drum Machine Expander Based on the Roland TR-808




Details via 8raw8:

"The 8raw8 is an Analog Drum Machine Expander, clone of the Legendary Roland TR808. It is designed to be an affordable reproduction of the original 808, without any compromise on the Sound. Each unit is unique, Handbuilt with passion in our little factory in southern France.

•11 Analog drum voices + Accent
•Separate Output for each voice
•Master Output
•Through Hole electronic components
•Ultra Fast MIDI processing
•BassDrum Tune Mod
•HandClap VCA Mod
•Rock solid Aluminium Chassis
•Quality Alpha™ potentiometers
•Moog Style rotary knobs
•Dimensions: 435x290x90mm (WxDxH)
•Weight: 3kg

What we wanted to achieve with the 8raw8, is a 1:1 reproduction of the old fashionned TR808 electronic circuitry. A simple, useful device focused on the authentic sound.

Every Active component on the signal path is the exact same reference as those used in the original 808. This includes: OPamps, transistors, diodes, signal ICs. At the exception of the HandClap VCA (orig:BA662), replaced by it's little brother (BA6110) sounding perfect with little tweaks.

When we recieve parts, we make sure they are true originals by testing them. It took ages to find the real deal.

We experienced a lot of Mods when prototyping, some were cool and ohters were just too crazy… In order to keep the 8raw8 authentic, we decided to include the most useful mods only."



•BassDrum Tune Mod: allows you to modify the BD pitch.
Adjust the BassDrum oscillator frequency in the key of your song, or create basslines using long decay settings (rather than DAW detuning).
Recall standard pitch by turning off the "Mod on/off" switch.



•HandClap VCA Mod: From soft clicky handclap to loud harsh CLAP.
Opening the VCA potentiometer in Maracas mode will create a cool white noise FX (the clap isn't triggered anymore)."

MIDI Interface



Each voice is triggered via MIDI note, including Accent.
The standard 1 octave midi mapping ranges from C3 to B3 (11 analog voices + Accent).

The 8raw8 is not velocity sensitive on purpose. It kills the oldschool drum machine vibe. Only Accent can accentuate the overall volume/tone on the desired steps of your drum pattern, just like the original 808.

MIDI Processing is very fast, allowing you to create those 808 'trap' drumrolls with ease."
