Twenty years after the production of Mellotrons stopped in 1986, Streetly Electronics introduced a new instrument in May 2007, the M4000.
From the outside, it looks like a M400; but a peek on the inside shows a cycling tape replay system similar to those of the Mark I, Mark II, SFX and M300 models. The M4000 is the first machine in almost forty years to include this system, which has been given up with the relase of the M400, in 1970.
The overall design of the M4000 was done by Martin Smith and John Bradley, with help from Norman Leete who created the microcontroller-based cycling system.
By default, the M4000 has 8 banks of 3 sounds each, for a total of 24 sounds.
The tapes are always 3/8″ and 3-track format. The M4000 thus makes it possible to have a large amount of sounds available without changing the tape frame, unlike the M400, where only 3 sounds are available at a time.
Streetly also proposes to have 6 tracks per tape, which allows to have a total of 48 sounds.
A dual keyboard version of the M4000 is available as the M5000. Both keyboards are arranged side by side as on the Mark V.
