Last post hopefully:
my 2nd H9 doesn't want to follow the midi clock anymore somehow that I set via the first H9 in the chain. My Mobius which is last in the chain updates correctly when changing the tempo on the first H9.
This has worked before so I'm not sure why it stopped working? I can't remember changing anything related to this.
midi channel is 1 on all devices, midi input clock is set to on with the second H9, no filter. Midi out is set to through on the 2nd H9
anything else I might be overlooking?
