Should I avoid the 4.9 update for my Indigo?

[ColdFusion588]

So I just kept going back till the keyboard stopped freaking out and now looking at the OS change list it seems fairly obvious why this is the case. 4.52 is where they started handing keyboard velocity differently. I gather this is why it's broken for older Indigos that still have the early keyboard controller board.

OS 4.55
- Velocity response of the Virus bc and Indigo have been completely reworked

OS 4.52
- Velocity response of the Virus kb has been improved.
- "no velocity beyond 96" bug has been fixed

At least I get the 1024 preset slots. I'd love to have the Save To Flash feature, better velocity control, panning for mutis and the new arpeggiator patterns but that's not going to happen without a hardware change. I will post back here about how Access supports this old issue.
