Hi Michael,

The Vibrato speed should be controlled by one of the LFO Speeds depending on the Mod Matrix assignments. I opened JSynthLib and changed the LFO1 Speed and used Midi-Ox and Midi-Yoke to view the midi commands. These are great midi snooping tools!
The LFO Speed range is 0-63 in decimal or 0 to 3F in hex. For LFO1 speed 0 JSynth sent F0 10 06 06 50 00 F7. For LFO1 speed 63 it sent F0 10 06 06 50 3F F7.
For LFO2 speed 0 JSynth sent F0 10 06 06 5A 00 F7. For LFO2 speed 63 it sent F0 10 06 06 5A 3F F7.

The youngmonkey site lists the midi ID for LFO1 Speed as 80 decimal or 50 hex which agrees with the messages sent by JSynthLib. The LFO2 Speed listed has a typo as it says LFO1 Speed. No matter, LFO2 Speed is 90 decimal or 5A hex which again agrees with JSynth.

If this is not clear or needs more explaining feel free to contact me and we can discuss this further. I'm thinking that the relationship between the LFO speeds and Vibrato was the answer you needed but since you mentioned the midi noob thing I explained the messages anyway. JSynthLib can be a real pain to setup and use so I admire you for getting through all that.
