GForce Intros M-Tron MkII Virtual Dual-Manual Mellotron


GForce Software has introduced the M-Tron MkII, a new plugin emulation of the Mellotron MkI/MkII. The new M-Tron MkII is a distinct product designed to sit alongside instead, than replace GForce’s existing M-Tron Pro instrument, which emulates the more commonly found Mellotron M400.


The original hardware came with 18 rhythms and accompaniments and 18 lead sounds, but the M-Tron MkII offers 66 of each and comes with 132 tape-banks, some of which have never previously been released.


M-Tron MkII was designed specially for producers and composers. All the sounds in the M-Tron MkII are sourced from the MkI, MkII and Chamberlin Tape Archive, which is curated by Streetly Electronic’s Martin Smith. In fact, it was Smith who prepared the recordings, with the tapes being restored and tempos remapped for the project.

The upshot of this is that the mic’d and DI’d versions of the lead tapes sit side-by-side the rhythms and accompaniments. In addition, there is a Dual Rhythm mode that enables you to layer two rhythms and accompaniments from the Chamberlin and Mellotron MkI and II, giving you the chance to create unique hybrids.


GForce recommends an 88-note keyboard for the most authentic experience, but you can also combine two smaller keyboards, with each assigned to a different MIDI channel.
