pplllleease don't get me all hot and bothered over nothing
i just got back from playing a festival in Victoria, i was the only guy there without ableton (+1 guy using serato) and it really hit home how hard it's been to create live sets with reaper.

i'm still having issues with audio device being interrupted when moving the play cursor, ie moving from marker to marker.

Thanks so much for giving attention to this issue!

I just tested it with two machines and Reaper v4.71 and 4.72 pre1 (I attach the video specs of both computers). Some weeks ago, I bought an NVidia GeForce GT630 card for my work machine and I was dissapointed to see that the performance difference with the common, native graphic card of the other machine is not really great.

In did the test you can find in the bug report (http://forum.cockos.com/project.php?issueid=5025) and the difference between v4.71 and this pre-release is subtle, but welcome anyway. For the sake of further enhancements, and now that you have put your hands on this, I propose a simple project for you to try :

https://www.dropbox.com/s/1rggowu0cv...rawing%202.RPP

There are 24 tracks with 71-bar midi items each. Doing as stated in the 3rd point of the link above I select the 24 items in the first track, open the MIDI editor and zoom in order to see approximately 44 bars. Then I sweep nearly 40 bars in a wide open, single CC lane. The slowdown is still severe, although it has improved. CC editing in multiple items is still problematic with this kind of performance. If you use CCs heavily in projects with many measures (+150 measures or so, which is not unusual in many genres out of the pop song context) even drawing and/or editing in a single item may still lead to a high level of sluggishness when the lane is wide open and you zoom out enough to see what you are doing globally.

As I pointed out in the link, let´s say that we´re talking here about the default 32 events per quarter note density. If one wants to increase it for any reason then things get, of course, notably worse as is expectable.
This must be all about the quantity of CC "sticks" that are shown on screen and the need of redrawing each and every one of them every time, or am I wrong? Unlike many users I personally like the "sticks" in the CC lanes -and don´t discard any other approach, by the way -, but if my conclusion is right, such a mass of UI data must be a hog for screen performance, isn´t it?

The rest of the performance improvements are just great, by the way!!

Again, thank you very much for paying attention to this just after posting it in the 4.71 pre thread. Further improvements will be really appreciated and, of course, will be tested thoroughly here.

If there's any chance of fixing undo of fader moves and item splits interrupting audio playback on mac that would be very good indeed. It's improved slightly but small changes like single fader move undos still often create a playback glitch.

This is the kind of pre I love... Performance improvements!

Any chance of improving sends/receives CPU load? They're the most resources hogs in REAPER

I will continue making improvements, however it's worth noting that with your project, and the MIDI editor configured to open all MIDI items, on my i7, drawing each MIDI editor frame went from 2000ms per frame (making REAPER unstable, really) to 400ms, a 5x speedup. I wouldn't call it subtle, but agree that more improvement is needed.

Thanks Justin, this is good news.

Great too see this. One of the main advantages of composition and performance oriented DAWs like Ableton is the lack of interrupted audioflow.

I would also really like it if we could "Save as..." without stopping playback too.

(I rarely use normal save, since I save to iterated filenames)

Matches the relationship between 4.70 and 4.72pre1 in my test with the project with one midi editor per project being set.

Are these the first results of the coming internal changes ?

The uninterupted audio is great.

Well, maybe subtle wasn´t the right word, you´re right... Anyway, thanks for your interest, Justin. Together with Tod I can say these are really great MIDI news.
