[RWP] Cockos Wiki Selecting items, may help with selecting trax?

Sat Oct 6 23:47:30 EDT 2012

I dont' know.  I can't make much out of this mousey discussion.  Thanks for 
providing it.  But, at the moment, it seems like there is a lot of confusion 
on our part over what is selected, and what isn't at any one time.  We don't 
have any good way of querying reaper for that, do we?
You can select an individual item on a track,  or the entire track, or 
multiple tracks.

So, knowingly stating some of the obvious, but just to try to summarize what 
we know.
Arrow up and down just selects the track you land on.
Shift_downArrow selects the next track as well.  So, now, 2 tracks, and all 
items on each, or selected.

What unselects them?

Shift+escape unselects everything.

To select non-contiguously, shift+space starts multiselection mode, and 
selects the current track which, presumably, was already selected.

Arrowint to a track in this mode does not select it.  Only when you press 
shift+space to toggle it's selection status.

Again shift+escape cancels all that.

It looks like item selection is a thing that you do only when only one track 
is selected.
Assuming that only the current track is selected,  It looks to me like,  if 
you have a track with 3 items, that if you go to the start of the project, 
then use control right and left arrow to get to item 1, then item 1 alone is 
selected.
If you now press control shift right arrow, then item 1 and 2 are both 
selected.
However, if you had just pressed control right arrow, with out the shift, 
the item 1 becomes unselected, and only item 2 would be selected.

If you press shift+downarrow, What happens?
Do all items on the track you just left become selected?  Probably so.

Using a time selection.  play to the start point, press 
alt+shift+leftBracket, play to the end point and pause, press 
alt+shift+rightBracket.  Now you have a time selection established, on the 
currently selected track or tracks.
If you now play, it will play starting at the right end of the selection. 
But, if you left arrow back just a little bit, so your cursor is  to the 
left of the time selection, and then play, reaper will just play from the 
cursor to the end of the time selection.  You can then determine if a time 
selection is present or not because, if not, then reaper won't stop at the 
end of the selection.

If you copy and paste that time selection, it just seems to create a new 
track.

I have managed to copy and paste a few bars of all tracks to the end, and I 
did it without gluing items.  But, I don't quite know how I did it yet.
But, I think it was jsut shift+down Arrowing, without thinking about items. 
I think I got the first item of each track.  So, there has to be more to 
that.

It seems to be that there are a lot of irregularities here, as chris pointed 
out.
Stuff doesn't seem to do the same thing twice.  But, I suspect it may be due 
to our inability to accurately tell what is selected and what is not.

I'll keep poking at this.  I have to admit that not being able to correctly 
identify stuff like that has me more than a little scared.  When I do 
projects in reaper, I save often, very often, just because I'm sure I don't 
always know what I'm doing.  And, losing the work isn't something I can 
afford.
So, mroe as I learn it.
Meanwhile, if I have something wrong, or forgot about something relevant, do 
flag me down.

> double-headed arrow.
> 2.Drag the Cursor to extend the Item. Each Loop Point will be indicated by 
> a notch in the edges of the Item.
> 3.Extend the Loop as required.

> Fade In
> A Fade In raises the output volume of an Item from 0dB at the start of the 
> Fade In up to the Fader Volume of the Track at the end of the Fade In.
> To create a Fade In:
> 1.Mouse over the starting edge of the Item until the cursor changes to a 
> Fade Cursor.
> 2.Drag the edge of the Item to the right to create the Fade In. The 
> duration of the Fade In you are creating will be shown to the right of the 
> Cursor as you drag the edge of the Item.
> 3.Release the mouse to complete the Fade In.
> You can also set a Fade In duration through the Media Item Properties 
> window.
>
> Fade Out
> A Fade Out lowers the output volume of an Item from the Fader Volume of 
> the Track at the beginning of the Fade Out down to 0dB at the end of the 
> Fade Out.
> To create a Fade Out:
> 1.Mouse over the edge at the end of the Item until the cursor changes to a 
> Fade Cursor.
> 2.Drag the edge of the Item to the left to create the Fade Out. The 
> duration of the Fade Out you are creating will be shown to the right of 
> the Cursor as you drag the edge of the Item.
> 3.Release the mouse to complete the Fade Out.
> You can also set a Fade Out duration through the Media Item Properties 
> window.
>
> Volume
> Item Volume is independent of Track volume. Item Volume can be set per 
> Item, or for multiple selected Items by adjusting one of the selected 
> Items.
> To set Item Volume:
> 1.Mouse over the top edge of the Item until the cursor changes to a 
> vertical double-headed arrow.
> 2.Drag the cursor to lower the Item Volume. The Item Volume will be shown 
> to the right of the Cursor and the Peaks will be redrawn to reflect the 
> change in Peak Volume as you drag the edge of the Item.
> 3.Release the mouse to complete the change in Item Volume.
> By default, you cannot drag the Item Volume above 0db. This behavior can 
> be overridden by pressing the SHIFT key while changing the Item Volume or 
> could be permanentely changed in the Media preferences dialog to have the 
> volume range go from -inf to +6dB.
> You can also set Item Volume and raise it above 0db by using the Volume 
> Fader in the Media Item Properties window.
> Item Processing
> The Item processing sub-menu can be found when you right click on an event 
> and consists of Normalize Selected Items, Auto trim/Split Selected Items, 
> Quantize Items Position to Grid and Move items to Source Preferred 
> Position
>
> Normalization of an event in REAPER is non-destructive and is extremely

> the item volume adjustment tip above, and that event's peaking at 0dB will 
> not produce audible digital clip noise unless either the master buss

> The Auto Trim/Split function is incredibly flexible and useful for drum 
> editing when combined with 'quantize item positions to grid'
