M-Tron MkII

Product Description

Rewind to the start

The GForce M-Tron MkII is a celebration of the insanely rare and highly coveted original dual manual trons, namely the Mellotron® MkI/MkII and Chamberlin® Musicmaster. M-Tron MkII is a distinct product from M-Tron Pro, yet part of the family.

Originally conceived as the ultimate Home Entertainment Console, the UK-made 1963 MkI/MkII was a dual manual tape-based instrument where the left manual’s 35 notes replayed a combination of 18 Rhythms and Accompaniments (66 on the GForce M-Tron MkII *) and the right manual (also 35 notes) replayed 18 lead sounds (66 on M-Tron MkII *).

M-Tron MkII was designed especially for producers and composers who want access to the evocative tones of the original dual manual Chamberlin®, Mellotron® MkI & MkII instruments with special emphasis on the Rhythms and Accompaniments which capture a moment in time between the 1950s and late 1960s.

If you are looking for a truly authentic MkII dose of nostalgia and host sync potential, you’ve found it.
