Reaper auto forcing 256 buffer size

BMW4LIFE · Messages: 2,361 Registration: 05.06.2003

I am unable to make Reaper honor the settings changes I make in the M-Audio Control Panel (I use the Ozonic interface) - for instance I change the buffer size from 256 to 512. The settings are saved when I close and reopen the control panel. However, when I launch Reaper (3.11) it auto-changes my control panel settings back to 256!! Can somebody please help? Also, I should note than when I go into the Reaper Preferences-->Audio-->Device and click 'ASIO Configuration...' it does not auto launch my audio control panel. I have to open that from the lower right hand icon (it's always running there). THANKS in advance for any help.

Same here. 2 Delta 1010LT cards both revert to 1024 samples any time reaper does anything. (v3.13pre5)

Reaper doesn't even store the ASIO device buffer size. Reaper asks the device what its "preferred size" is, and then initializes the device using that buffer size. The driver is supposed to report whatever it is already set to as its preferred size. Does whatever application you are using to change the buffer size have any further options (like "use this buffer size as the default", or something)?

Reaper buffer size issue : Solved

I had the same problem. My case would be different than yours but I hope that this helps: I use sfz sound font player and have M-Audio 2496. Apparently running standalone sfz was causing the problem. So I run sfz and while it's running on the m-audio control panel I changed the buffer size to 384 and closed the sfz stand alone. problem solved reaper doesn't change the buffer size anymore. If you use any vst either inside or outside the reaper that changes the buffer size that may cause the problem.

did you stop playback? anyway, im using an old st-audio soundcard that behaves somewhat similar. try this: in reaper open the soundcard-config window, THEN open the cards own config-thingy and change it there...that works here. always figured it was an ussue with the card i currently have...guess not. worth mentioning i that i have used a 2496 from m-audio before without this problem.

I just got myself a second M-audio Delta1010lt and I'm having this issue too. Setting 64 samples buffersize, Reaper changes it to 256. Is this a problem w Reaper or the drivers?
