There is already MIDI Send Delay feature and it is great when sending multiple messages from MC8 Pro to the target device which does not handle multiple messages reliably. Now, when sending multiple messages from another device via MC8 Pro to this kind of target device, it would be great to be able to increase the delay so the target device is able to handle those messages reliably.
Example setup: handling AXE-FX 3 presets/scenes/effects with its own FC-12 foot controller. Sending PC and CC messages from AXE-FX 3 to MIDI controllable amplifier head to control different amp functions by using AXE-FX 3 Scene MIDI blocks or Control Switch MIDI. Amplifier head does not respond reliably to those messages. Those multiple MIDI messages can be sent directly from MC8 Pro to amplifier head and it works great when adding a small extra delay to those messages by using MIDI Send Delay feature of MC8 Pro. So, to get those multiple MIDI messages sent by AXE-FX 3 Scene MIDI block or Control Switch MIDI to amplifier head working reliably, MIDI Thru Delay feature needs to be implemented to MC8 Pro (if it is a software MIDI Thru).
MC8 Pro MIDI OUT → AXE-FX 3 MIDI IN
AXE-FX 3 MIDI OUT → MC8 Pro MIDI IN
AXE-FX 3 MIDI Thru → Amplifier head MIDI IN
