Losing first notes at looping

[pyriet]

hello,

when try to loop pieces of the timeline (begin/end marker + loop button on), it appears that (except for the first run of the range), i'm consistently losing the notes at the begin marker of the loop (they don't play).

is there anything i'm forgetting about, or is this a bug?

i'm using muse 2.0 (Debian package version 2.0~rc2-2).

thank you for this wonderful software!
