I feel that getting third-party manufacturers involved is the only way to stop hm7000 going the way of the Zero-One.
They need to find some way to "open" the devices up so that third parties can produce sound/function profiles, they need to find some way to co-operate. In my mind, ideally, open sourcing the APIs necessary to communicate with the chips so that control can be built into other devices and other parties can produce compatible decoders.
DCC won out through co-operation, without co-operation I'll be buying a new DCC control system in 5 years time to replace the hm7000.
I like HM7000, it's a great concept and finally brought me into DCC Sound, I just don't want it to wither on the vine because there is only one company supporting it...
