I’ve just downloaded the demo for Ardour 5.9, it looks like a fantastic DAW that could work really well for me. But I’m getting some extremely high DSP usage with only a single audio track looping a short drum loop. With no plugins and the Buffer Size set to 512 samples the DSP meter is over 50% and frequently hits 90%+. I’m getting audio dropouts and the loop doesn’t repeat perfectly (getting a slight delay every time the playhead loops back). Upping the buffer size helped a little but in Max/Logic/Ableton I can easily run multiple tracks/plugins with buffer size 128. Running a Mac Core 2 Duo 2.53GHz from 2009 so it’s not the fastest machine these days, but considering it handles other DAWs fine I’m wondering if I’ve set up something wrong? I have selected “all available processors” under DSP CPU utilization but not a lot of improvement…
I understand from the documentation that I shouldn’t expect Ardour to necessarily match commercial software in capabilities but this seems pretty unusable at the moment. Otherwise the feature set looks amazing so I’m really hoping to get it running properly!
If I’ve missed something really obvious I apologise in advance.
