- Create a single track that transmits on the IAC Bus. No particular MIDI channel. No MIDI Input
- Open a MIDI Monitor application and turn off "clock" under realtime so you can see what's going to happen.
- Add a MIDI Effect Rack to that track.
- Create two chains in that rack. Give them names.
- Right click the chains and select 'Show Names in MIDI Editor'
- Limit the KEY range for the chains to G-1 for both chains.
- Limit the VEL range for the first chain to 1, and the 2nd chain to 2.
- In the track, create a new clip.
- Add a G-1 to the first and 3rd beats.
- Set the velocity on the first note to 1 and the 2nd note to 2.
- Loop the clip.
- Play the clip and watch the MIDI Monitor.

The monitor should be reporting an event on G-1 with velocity 1, and a 2nd event at velocity 2 but it reports both instances at velocity 1. If you expand the velocity filter for the 2nd chain to cover both 2 and 3, then the velocity 2 is sent. If you expand the 1st chain's velocity filter to 1 and 2, then move chain 2 to 3 and 4, you get a velocity sent of 1 and 3 when the notes are hit (provided you dial the 2nd note in the clip to velocity 3.

This makes zero sense. Anyone know why it would do this?

works fine here, both on the midi track with the midi effects rack, and on a new midi track taking its input from IAC. MIDI Monitor reports "1...2...1...2..."
