Hi,
I recently got a Focusrite Saffire Pro 40 as my new audio interface, computer is a notebook with an i7-620 CPU, 4 GB, TI chipset firewire express card.
However the Pro 40 is not really running smoothly with the Focusrite ASIO drivers on Windows 7 x64 - crackles, dropouts, event with larger ASIO buffers.
For comparison, I switched to my built-in audio card with the ASIO4ALL driver and to my surprise, this was running nicely with an ASIO buffer of 64 bytes! At 64 bytes buffer, the ASIO4ALL driver is running without glitches up to a medium load. If I increase the buffer to 128 bytes, everything runs rock solid even if I put a heavy load on the system. So it looks as if my system itself (drivers, hardware) is really capable of delivering low-latency audio (I have done some tuning - disabling unnecessary devices and services, DPC latency checker is "all green".
And now the real surprise: when checking the parameters of the ASIO4ALL control panel, I noticed that besides the internal audio tested successfully as described above, the Saffire PRO 40 was also offered as an 8-channel input/output device.
So I configured ASIO4ALL to use the Pro 40 with an ASIO buffer of 128 at the ASIO4ALL side and the Pro 40 also configured for a 128 buffer. And - strange enough - this seems to work nicely. I played for an hour or so, all fine, no problems at all.
As this is still running with the Pro 40 in the back end it looks a bit to me as if the problem with the Pro 4's native ASIO driver is not my system environment or the hardware but probably the Pro 40 driver itself - I cannot understand how the combination of ASIO4ALL and Pro 40 driver, each running at 128 buffer size is running very stable and the Pro 40 driver on its own is not running completely stable even at more much than 256 bytes buffer size.
My questions to this forum - why is ASIO4ALL showing the Pro 40 as an 8 in, 8 out interface - where is this information coming from?
The interface has much more inputs/outputs which are all visible in the native ASIO driver - 8 mic/line ins, 10 outs, 8 ADAT-ins, 8 ADAT outs, SPDIF in/out, 20 internal virtual outs for DAW subgroups, etc. Is this configurable somewhere or is the Pro 40 driver telling ASIO4ALL "I have only 7 ins/outs"?
Best regards
Chris
