Julien, what i meant was, if i set the playback start point to 15.0, then when i hit space, it actually starts from 15.0, in REC mode, and doesn't automatically "jump back" to 2 secs before 15, or something like that. (A common feature in the miserable GUI DAW world.) Sometimes the playback goes a little weird and doesn't always want to start where i set it. (I'm sure this user error, as another post i made concerning setpos, and what actually happens in relation to engine state.) I'm using jack_metro for metronome, which works quite well, and i can silence it in my hardware mixer. Best of all, of course, no need for a GUI. :) Regards, Alex.
