Protocol specification for MX series

I understand the MX-Edit software is only available in 32-bit and there are no plans to provide a 64-bit version. Apple removed support for 32-bit software from macOS in version 10.15 (Catalina), so MX-Edit can not be used on the current version of macOS. This is of course a bit of a disappointment for owners of Lexicon MX devices, like myself.

I would like to request the following: Could Lexicon provide technical documentation on the protocol (SysEx?) used by Lexicon MX series devices? If so, software developers could develop a 64-bit (open source) alternative to MX-Edit. (I’m a software developer myself, although I’m not yet familiar with DAW plugin development.) I think that if we can make this happen this would increase the usefulness of these devices (which are still sold!), which would be a big win for both Lexicon MX users— because they don’t lose the ability to control their Lexicon MX hardware from their DAW software when they upgrade or replace their computer — and for the Lexicon brand as well, because happy users are always better for business than frustrated ones.

I hope Lexicon will consider giving its customers this opportunity by publishing this protocol specification.

    That is correct, further cementing that is the MX Series is slated now for EOL and will be discontinued soon. We have no Catalina workaround no.

    I can pass your suggestion onto our product dev and see what they say, there is no guarantees but can definitely pass on the request for that.
