Synths ⇝ Korg ⇝ Korg M1R

The Korg M1R is the rack-mount version of the popular M1 synthesizer workstation. It has 4 MB of sampled waveform ROM and uses what Korg's first generation of ROMpler technology, called "AI synthesis".

The 8-track sequencer can store up to 10 songs and 100 patterns. Default patch and combination memory is 50 each, but it can be doubled to 100 of each by allocating some sequencer memory to patch storage, and that will reduce sequencer memory to 4400 notes.

The internal sample ROM can also be expanded with the EX-M1R 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. A large library of expansion cards was released by Korg and other third-party manufacturers. An MCR-03 RAM card can be used for storing additional patches.

The Korg M3R is a lower-end 1U version of the M1R with fewer samples and its own line of expansion cards.
