# Two Notes

# Opus
There is a delay when changing presets on the Opus, when sending a PC message.

In the video below, the Opus is connected directly to the Timeline MIDI Thru port. Both are responding to the same PC message on the same channel. You can see that the Opus takes longer to change presets as compared to the Timeline.
