Setting the Recording Format

Logic Pro allows you to set the recording format of channel strips, as follows:

Mono: One circle represents a mono input format. The level meter shows a single column.
Stereo: Two interlocked circles represent a stereo input format. The level meter divides into two independent columns.
Left: Two circles, the left one filled, indicate a left channel input format. When this input format is chosen, only the left channel of a stereo audio file is played back. The level meter shows a single column.
Right: Two circles, the right one filled, indicate a right channel input format. When this input format is chosen, only the right channel of a stereo audio file is played back. The level meter shows a single column.
Surround: Five circles indicate the surround channel input format. The level meter divides into multiple, linked columns (the number matches the project surround format).

To switch the recording format of a channel strip

Select the channel strip’s Format button and hold down the mouse button, then choose the desired format from the pop-up menu.
