It was a little difficult to make adjustments to groups of notes. Also the Instrument list was a bit long ..
Instruments are now listable in groups.
Now you will see a multi/single selection option button at the bottom-left of the sequence window. Going to multi-selection mode will enable you to select as many notes as you wish and apply changes to all of them as a group.
There is also a extra options button on the note selector popup - Here will give you the options of select the whole channel, select all notes after the primary selection and an option for selecting all notes of the same semitone. That last one may seem like a strange choice but it can be great for changing percussion on channel 9 ;)
