Hi

The tempo change clicking issue was different than the asio issues.

Beta 313 attempts a general cleanup of asio playback. I hope it fixes most issues. If you still have issues please let me know the details (symptoms, sound card, OS, type of computer, etc).

One thing that MAY affect some folks. I don't know if this will happen, but it is possible-- Because the new higher-quality Elastique tempo stretching uses more CPU, some people may need to use ASIO buffers a little bigger than they previously could get away with, if they like setting buffers "as low as they will go".

I tested several ASIO drivers and sound cards on the same Windows 7 quad-core computer. Some drivers and sound cards just seem a little more efficient than others. On some drivers buffers as low as 2 ms played fine, but on others I needed to use 5 ms buffers. On slower computers the buffers might need to be bigger than that.

Some (especially older) ASIO drivers are/were very temperamental. If an old ASIO driver was temperamental in the past, then it might still be temperamental!

I haven't used ASIO much since I got the Windows 7 64 bit computer. It was surprising how smooth some of the newer drivers run on the 64 bit system. The newest version of ASIO4ALL worked great. The Creative ASIO driver for Creative XFi card seemed very well-behaved. The driver for the Focusrite Saffire is very pleasing (as is the little Saffire audio interface box). Maybe there are still some manufacturers newer drivers out there that are still temperamental, but the above seem very good quality as best I could tell.
