The M1 is one of the first fully-sample-based digital synthesizer workstations, using what Korg calls "AI Synthesis". It was very popular, selling about 250,000 units during its production lifetime.
The internal sample ROM can also be expanded with the EXK-M1 ROM expansion kit, doubling the wave memory to 8MB with 275 PCM samples. It also has two card slots - one for a waveform card and one for a patch memory card, and a large library of expansion cards was released by Korg and other third-party manufacturers.
It uses a standard CR2032 lithium battery to maintain its memory.
