GForce Software has released ChamberTron-RE, a Rack Extension for Reason. They say that, inspired by the tape replay keyboard originally invented by Harry Chamberlin in the 1950s, which, via a fascinating twist of fate, gave rise to the Mellotron. Effectively, the forerunner to the Mellotron, Chamberlin instruments were conceived and built between the 1950s and 1980s by a US inventor of note, Harry Chamberlin. Because of a dislike of Rock & Roll, Harry recorded instruments that (with the exception of the shared Three Violins sound) differ markedly from those of the Mellotron, and many claim that the Chamberlin recordings are more 'open' and 'natural' sounding

A spokesperson told us, "ChamberTron-RE provides a highly evocative set of sounds within an easy to use and carefully crafted Rack Extension."

Here's more details direct from GForce and Propellerhead...

Remaining faithful to the 35 note, 8 second limitation of the original Chamberlin M-series keyboards, ChamberTron-RE gives you direct access to 35 coveted tape banks curated by both the original British Mellotron® manufacturer, Streetly Electronics, and the GForce Software Chamberlin instrument collection.

Use ChamberTron-RE either as a straightforward playback device for these rare and iconic sounds, or, via the dual-layer and comprehensive editing features, create your own bespoke, hybrid patches which inject all the character from yesteryear without the expense of owning and maintaining an original Chamberlin tape replay instrument.
