jupiter8:
Do they have the same sysex identifier IE 0x70
They do
jupiter8:
it simply a 7 bit with 3 bits zeroed and if so which bits ? The first or the last ?
It is – the data uses the 4 ls bits. Se the "Sending Key Presses via MIDI" document on the H8000 support page for examples.
The SYSEX_SCREEN_DUMP is for experts only. You should not even consider using it if you don't have an H8000 to get test messages.
jupiter8:
Is it possible to communicate with the H8000 via Ethernet or is midi the only/by far the simplest solution ?
No Ethernet. MIDI is probably best for you as Eve/Net is a proprietary non-standard protocol.
jupiter8:
Does the EVE/NET controller get it's screen data via midi ?
No. It uses Eve/net which runs at up to 1MB/sec
