0.2a performance

[UpTilDawn]

I am a little leary of doing the SS recording from the same input devices... although it is working if you have enough cpu power.

Hopefully, the direct hooks will ease the load for that scenario.

I'm confused...
Is your concern over using the same drivers... asio for both SAC and SAW for instance?
How is what I've been testing with asio for SAC and mme for SAW any different, if at all?

There is quite a load in the background when using the same soundcard in both apps at the same time... whether using the same asio driver for both (if possible) or using Asio for one and MME for the other.

It is interesting to see it work... but this would not be my prefferred method.

The hooks I am working on eliminate the use of any driver at all in the SAWStudio app... it receives it's data direct from the SAC channels thru an internal shared buffering scheme... this will hopefully allow more stability with less Windows system interaction between the two apps.

less Windows system interaction

Ahhh, the holy grail ...

So, out of curiosity, what (if any) is the difference between using the same driver or different drivers to run the apps together?

There is no difference potentially if both methods work... but that depends totally on the driver and its cpabilities and then what goes on at the low level inside the hardware to make that happen.

But... you do have the extra load of processing the driver code twice for each chan of data.

Okay.

I tried both ways initially and at first had trouble using only asio for both apps, which caused a lot of static-like sounds to be recorded to the tracks in Saw. A second attempt a couple days later produced no such problems.
The mme/asio combo seems to work okay, but as you say, at a cost.

finally tried out 0.2a today... got it running stable at 1X48 with my Fireface. Nice!!! Can't wait to try it out at a real live show this summer. ...had my nose to the grindstone over the last 3 weeks on an album so I really haven't had too much time to play with SAC. How do you tell if buffers are slipping?

Left-Click on the LIVE lite and a popup message wil tell you the status.... and do realize that the slippage is self correcting now so you will not drift latency.
