The Korg MSC-2S "Synth 1" card set is an expansion bundle for the vintage Korg M1 series of synthesizers. It consists of two matching ROM cards: the MSC-02 PCM card (sound waveform data) and the MPC-02 Program card (preset programs and combinations).
Compatible Synths: Korg M1, M1R, M1EX, M1REX, T1, T2, T3, T2EX, T3EX (the PCM card also works with the M3R).
Unlike factory card sets focused on acoustic simulations or traditional instruments, the Synth 1 pack is tailored for electronic music production:
