[LAU] Using a pe-count with Renoise/Ardour

Hello, I have some tracks in Ardour, acoustic instruments, to which I counted 8 metronome ticks before starting recording. So there are 8 clicks of 'silence' before the instruments starts. This is a sketch, so I'd like to play around with Renoise while the instruments are playing, especially pattern-based. The problem is that Renoise starts immediately, same time as Ardour, so that music starts happening when Renois is already at 32 (out of 64, default size). I tried adding a metronome pre-count in Renoise, then use Renoise to start Ardour, but the pre-count does not take effect. Is there a way to be able to play around looping a pattern in Renoise while Ardour plays tracks, assuming that the tracks were recorded with Ardour's metronome, and that a 64 pattern in Renoise fits nicely in what is unfolding as recorded. In other words, is it possible to jam in Renoise while audio tracks are playinbg - surely it is ! But is it possible to do it using a metronome count-in before looping a pattern ? Of course, any suggestion of achieving this in a better way is welcomed ! (ツ) Cheers.
