Tone.js: Starting transport with two synced Players starts them at the wrong time.

This might just be not understanding how Transports work, but I read the manual and the wiki (and a couple of bug reports here) and there’s nothing that makes me think I’m doing it wrong. If I am, sorry 😃

I have a Codesandbox to repro the code here.

What I’m trying to do is: having 2 Players, I want to schedule them (in TransportTime) within the Transport, then start the Transport at some point in time. I expect that, if I sync() the two Players, start() them with a startTime argument and finally start the Transport, they should be playing at their respectively correct startTime after I started the Transport. In other words, if I do:

    player1
      .toMaster()
      .sync()
      .start(1.555)

    player2
      .toMaster()
      .sync()
      .start(4.1)

    Tone.Transport.start("+0")

I expect player1 to play 1.555 seconds after the Transport is started, and player2 to play 4.1 seconds after the transport is started. For simplicity’s sake, in the example I start the Transport immediately (in Context time), but if I started it in +1 seconds, I’d expect to hear player1 2.555 seconds later and player2 5.1 seconds later.

What I hear, instead, are the two players starting at the same time, after some 12 - 13 seconds (again, see the example project here).

Is that a bug or am I getting it completely wrong?
