WHAT ARE RIP OFF DUBS? THE CONCERNED CHRISTIANS UNIQUE DIY KEYBOARD
The keyboard was designed and created by Concerned Christian DD. He built the thing from scratch and one of his aims was to have unlimited polyphony. At the time most keyboards had limitations. Some were monophonic (could only play one note at a time). But most professional keyboards could manage at least four notes simultaneously. DD wanted this keyboard to be able to play as many notes as you pressed at the same time... if you put your arm down on the keyboard pressing all the notes then all the notes should play. This design goal was achieved making the keyboard fairly unique for it's time in this respect. In addition it had a pitch bend that was tied to all the notes too. So not only could you play all the notes at the same time but you could pitch bend them all at the same time as well. The keyboard consisted of a electronic string section which was based on a design published in ETI magazine (Electronics Today International) and it also had a Voltage Controlled Filter from the same source. Other original components designed by DD included a programmable sequencer which could play back from either an internal clock or from an external audio trigger (e.g it would play one step and move forward one step in the sequence on being triggered from a drum). It's important to note that at the time this keyboard was designed computer music did not exist outside of experimental labs. There was no such thing as MIDI and the Fairlight (the first sampler) had not been invented yet. Above: The sequencer section and controls The keyboard continued to be developed through the years. It was planned to add a sampler to it and all the computer parts had been purchased to do this (Z80 based - the computer of the moment at the time was the Sinclair Spectrum). However, then DD moved to America and the project and keyboard were abandoned. Through the 80s music technology rapidly advanced and very quickly the keyboard, now not being upgraded, fell behind and became irrelevant. However, in the Rip Off Dubs you hear it used in it's moments of glory when it was ahead of it's time. Mostly to pick out simple melodies - but none the less a DIY icon of it's day. As you can see from the photos DD did not bother too much with fancy casing. It was more punk to have the circuitry exposed - and easier access to fix or upgrade.

We'd encourage you to create (rip off) yours too. This discography is complete for the Concerned Christians only. Notable others are mentioned.
