The Mellotron M400 is my all-time favorite instrument!
Owning one is my deepest dream but these piece of history are rare, expensive and, most of all, highly unreliable!! Rick Wakeman himself even set his two Mellotron on fire in a middle of field after struggling for hours with tuning problems!

This is why I decided to build my own, but instead of having the samples stored on tapes, the samples are now stored on a SD card. The filter and amplification circuit is on the other hand fully analog to keep the sound warm and authentic!

Status: Finished

Specs:

- MIDI connection
- Up to 20 sound banks
- Half Speed Mode
(Feature used on the Streetly Electronics M4000)
- Split Mode to play with 2 separate banks
(like the Mellotron MkII)
- Analog Filter
- A LCD screen

I've finished the pcbs but i have made some bugs.
I could send you some but I'd rather have them ironed out.
And if Mr soulmachine is ok with I could sell them to you

@JanWa, Do you have the gerber files?

@JanWa, @Anonymous, I have a CNC too if it is simple enough I can mill them.

Hello World! Thanks a lot for you amazing support!
As for the PCBs, the Modular Synth company that wanted to license the project finally decided to focus on something else... If anyone here is interested in building and sell PCB for the MS-X, please send me an email or contact via my Soul Machine Facebook page!
Cheers!

@Anonymous, no unfortunately, I built everything on breadbord PCB based on the schematics I drew
