Midi from eurorack vs midi from daw.

Hi, I've tried running the midi out from erica black sequencer to a yamaha tx81z which works fine, I recently got a novation zero sl mkii to control the tx81z via sysex, the midi signal is getting to the tx via the novation fine but the sysex won't work, this setup works great if the midi is coming form my daw, is the midi differnet? I assumed the sysex was coming from the novation so it wouldn't matter where the midi was coming from but it obviously does, any ideas??

Well, I would first check the incoming data with programs like MIDI Monitor (Mac OS) or MidiOX (Windows). :)

I got it working, the sysex from the novation with the erica sequencer midi going thru it will only work if the tx81z is set to receive on midi ch1, doesn't seem to work with any other channel.
