This project first came to light in July when we saw some images of the ARC Serge TKB prototype. ARC have just released an introductory video that nicely goes through all the functionality.
The original Serge TKB is designed for the Serge/Buchla 4U format and is the traditional input device and sequencer for that system. Celebrated for its versatility and creativity ARC is bringing this officially licensed version to the Eurorack format which makes a lot of people very happy.
It’s a touch activated keyboard sequencer for the creation and performance of control voltages. Electronically it’s identical to the original Serge Systems TKB from 1979. It combines the functions of a touch-sensitive keyboard, programmer and sequencer. The 16 touchpads are seen to exist in columns of controls, called “stages”. Only one of the stages can be active at one time either by touch or sequence. At the top of each stage is a gate output giving 5v when active. The four knobs, known as A, B, C and D from top to bottom set the control voltage.
On the right-hand side are 8 output jacks containing individual and mixed outputs from the pots. There’s also a key output from the touch-pads, a gate and a pressure output. Next to the outputs is a column of inputs including clock, hold, up/down, random and reset. You can also turn the keyboard off.
The Serge TKB is a whopping 70HP wide, it almost needs a standalone case by itself. Actually, that’s not a terrible idea as it might be a bit awkward to play in some Eurorack cases. It’s priced at $899 which is about $2000 less than the Serge system equivalent.
There’s another video coming soon demonstrating patch examples and the sequencer in use. The ETA is still “coming soon” but it can’t be too long now.
