Well.. the great thing is that they do add features rather than release a "new" model with new features, like pretty much everyone else.
Make the request... I think that would be a great feature. It could include a config option that scales how far the rotary switch advances with each click.
Overall, the 722 is an awesome machine. There are only three total issues that I have with it, which are:
(1) Inability to scale the meters
(2) Inability to swiftly scroll through files (this issue) and
(3) The ridiculously slow transfer via Firewire, when USB decks that I have had, transferred data at least four times faster.
At your suggestion, I will forward these comments to Sound Device.
