MOM (Master Of Modules) manages synthesizer modules to make them work as a single musical instrument.  The main responsibilities of MOM are

• Control patching.
• Control parameters.
• Organize voices.
• (possibly) Organize modules such as device ID management.

Designing and implementing MOM and synth module data model is yet another challenge out of building CAN network.  Basically, the inter-module communication depends on CAN physical layer, but it’s a pain to dragging such a dependency during the MOM development.  I’m sure the CAN network would be quite unstable at first and I don’t want to stop and troubleshoot CAN while I’m working on MOM.

So, in order to remove dependency on CAN network, I’ll build the initial version of MOM based on TCP/IP with dummy (stub) synth modules that are purely software oriented and talk TCP/IP.  Once the MOM design is fixed, I can replace the TCP/IP driver by CAN driver later.  It will not ruin the module data model.
