I think one issue (for me) also seems to be that the transport doesn’t always accurately start with an MTC start signal. So this way the sequencer or arpeggiator can easily be misaligned with the source start.
This combined with the added jitter can really be quite impossible to use.
right, another thing to take into consideration too.
I was just talking with Robin @x42 regarding how Ardour does the MTC side, have some good pointers for things to look into once MOD can dedicate some time for this.
updating the step sequencer is still a good step, and allows to quickly test/check if the clock sync is working proper.
and I am thinking having such clock as CV pulse in Cardinal might be quite handy too, for driving things based on a hardware timing rather than the DAW/Host.
