Add-on units expand the system’s capabilities:
“The Clap” delivers a decent handclap sound with controls for noise mix and decay, though it lacks trigger integration with the main Kit.
“Synkit” produces versatile synth-drum sounds with pitch sweep capabilities, ideal when triggered from the main Kit’s toms, although its decay control is finicky.
“Tymp” offers low-pitched, noise-heavy sounds more suited to effects than traditional percussion, but suffers from inconsistent sensitivity and lacks adjustment options.
The best news... that's not the only article on the kit you can find online - there is also another link to an article from Muzines from the January 1984 issue of Electronics & Music Maker. It includes similar info, but also introduces us to the Bass Drum Pedal/Hi-Hat on/off accessory that can be connected. Also included is pricing info - always a treat to see!
One weird Amazon link that popped up was to "The Kit Operating Instructions", providing us not just with a colour image of the main unit, but a summary of the history of the company. Summarized from the page:
MPC Electronics Ltd was founded in 1982 in Cambridge by Mike Coxhead to produce and market "The Kit," a compact electronic drum trigger device invented by Clive Button, designed to be played with fingers instead of sticks.
After refining the design, the improved Mark 2 version gained acclaim at trade shows and sold widely in the UK, Europe, and North America. The company released complementary accessories such as bass drum pedals and sound modules like The Clap and Synkit.
In 1983, Button introduced a more advanced version—the Music Percussion Computer—with eight pads, onboard memory, and compatibility with home computers, influencing future products by Roland and others. MPC later developed full-size drum pads and synth modules, but despite several innovations, the company folded in 1986 after Button moved on to work for other firms. Many units of The Kit remain functional today, and a comprehensive manual and history booklet documents MPC’s contributions during its brief but impactful existence.
Here's a picture of the unit in colour... gotta say, I wasn't expecting the red or the gold.
