Note: The issue described below is resolved in Logic Pro/Express 7.2 or later.
When you cycle audio in Logic, and the SPL (Song Position Line) reaches the end of the cycle zone and jumps back to the beginning, Rewire audio streams may drop out completely. If you stop playback and then start it again, the audio returns.
This issue occurs if the selected track in the Arrange window is an Audio Instrument track whose LFO is tempo synced to the song. For example, if you assign the ES2 synth to the selected track and set its LFO to 1/16, 1/8, and so forth, this issue will occur.
This doesn't happen if you set the instrument's LFO to a specific rate, such as 1.12 Hz. If you select a different track in the Arrange window, the issue will not occur.
