Message Ordering
Within a section, messages are sent in the order they appear in the editor — top to bottom. All messages in a section are sent in rapid succession when the section is activated.
If your amp takes time to load a preset, put the PC message first in the section so it starts loading while subsequent CC messages are being sent.
MIDI Timing
Messages are transmitted at standard MIDI speed (31.25 kbps). A full section of 10 messages transmits in approximately 10ms — well within any practical latency tolerance.
