As mentioned in the Ideas forum:
I'm using a Korg Nanokontrol with the transport controls mapped to Audiomulch using 'parameter control' / Quickmap midi'
I have a nord micromodular synced up to receive midi clock from AM.
If I click the 'Play from start' control with my mouse, The Nord starts from 1 even if it's been stopped midway through a 16 step sequence (as you'd expect)
If I use the Nanokontrol it doesn't reset to 1.
It also seems that it actually maps the 'Play from start' button to the 'Play' button - also if I assign the 'rewind' button on Nanokontrol to 'go to start' and then press 'Play' on the Nanokontrol, this also doesn't reset the midi clock.
Hope that's clear!
