Compatibility
The M-256F is designed to work seamlessly with numerous Roland devices, including Alpha Juno 2, GR-700, GR-77B, MKS-10, MKS-20, MKS-30, MKS-70, MKS-80, TR-707, TR-727, TR-909, JX-8P, and JX-10.

Effortless Memory Bank Selection
The M-256F functions like having four Roland M-64C cartridges in one, with four independent memory banks accessible via dual-switch configuration. Switch between banks with ease and on-the-fly, or possibly store different devices' data on each of the memory banks.

Additional Options and Compatibility
For users prefering a single memory bank, a streamlined battery-free version (M-64F) is also available.
Another multi bank solution is the M-4096F, which offers sixty-four M-64C compatible memory banks.
