Feature Request: Modular Synth Designer

I know this is kinda crazy but i would like to see this feature implemented in a future version of LMMS.
This would require a lot of work for the core team to code and implement, but please kinda bear with me as i explain this.

The feature I request is kinda a like a patcher, but is much more more complex. It would be like the Native Instruments REAKTOR, where we could create our own Synths and Effects.... But this would be directly inbuilt inside LMMS.

I got this idea from the famous VST Maker Software "SynthEdit", but later i found that REAKTOR kinda does the same..

An idea how this would work: The users can create a Instrument/Effect using patches (like SynthEdit) connect them to the output.. This instrument can be distributed in the form of files (a fixed file format exclusively for LMMS) and other users can use them too. Also the creator of the instrument will have the ability to lock the Instrument/Effect so that other users can't see or modify the instrument, but unlocked Instrument/Effects can be seen and edited as per their wish.

Tell me if this needs some more info..

The issue names no files, tests, or entry points; begin by reviewing the proposed modular instrument/effect scope with LMMS maintainers. A complete result would need an agreed design for patch connections, a reusable file format, and locked versus editable instruments before implementation can be assessed.
