[Rwp] Odd behaviour when adding an effect

[Justin Macleod]

You also might want to look in the audio devices section of the preferences tree and play with the settings there. Using wave-out rather than Direct sound, or wasapi rather than wave-out, or a c o rather than all of them if your sound card supports it and you have another sound card for speech, will reduce your latency. Also play with the block settings. On a good day my laptop can do a block size of 128, on a bad day, when I haven't been bothered to close other applications or when I'm dealing with high sample rates etc, I need to set it to 512. You shouldn't pick values that aren't in that progression - 64, 128, 256 etc as, apparently the processor has to work harder to support those values or something. 

Also, Reaverb is one of the more resource-hungry plug-ins because of the nature of convolution reverb. There is a checkbox in the plug-in dialogue, two in fact, labled ll and zl respectively. LL stands for low latency and zl stands for zero latency. I check the zl box and it seems to help a lot.

Thanks for that info. I'm based in the UK, so I imagine that I'd be better off purchasing closer to home. However, I'll definitely look at the specs and consider what's best for audio.
