Hi. I've having trouble with my 12 Step freezing when sending a note. When it freezes, the 12 Step becomes unresponsive to all MIDI messages. The only way to reset the 12 Step is to unplug the power and then plug it back in again. Based on trial and error over the past week, it seems to freeze when the following 2 conditions are met:
1. The 12 Step is powered via the MIDI Expander.
2. The 12 Step is in Legato note mode.
If the 12 Step is powered by my Macbook's USB port, the 12 Step does not freeze even in Legato note mode.
If in Normal note mode, the 12 Step does not freeze even if powered via the MIDI Expander.
My setup (for live performance) is designed to have the 12 Step powered by MIDI Expander; providing power by computer is not a very attractive option.
Has anyone here had a similar experience, or can offer any suggestions/advice?
Thanks!
