MPC Electronics MPC-1 with Tubbutec uniPulse MIDI retrofit
video upload by Harry Axten
"Pretty rare British-made drum machine from 1981, originally intended to interface with the Sinclair ZX81 computer. I’ve installed Tubbutec’s excellent uniPulse MIDI retrofit in this, using the existing sync socket for the MIDI input. The drum voices are very responsive to playing dynamics, which I was pleased to find works great with the uniPulse’s velocity-sensitive outputs.
The sequencer board in this one was wrecked by a battery leak, which is sadly very common in these. The leakage also got onto the main analogue board, although fortunately not as badly. It ate up three of the potentiometers for the Tom 4 voice, and I haven't yet located suitable replacements, hence those controls being missing and blanked off; but everything else is now working as it should, having cleaned up corroded board traces and replaced a number of damaged components."
