Hi Mac...

Okay - 1, as you would know, if audio sample rates between two devices are mismatched you get all sorts of artefacts and digital noise. I am using the spdif out from my keyboard to the Presonus Firestudio M. The keyboard has a FIXED sample rate over spdif of 48, ergo the PFM also needs to be at 48.

2. I am using BIAB for the playback of songs only, NO recording...and in essence a wav/wma file at 44 will still play fine if a device is set to 48, or even 96. I can understand if I was recording audio but I am only playing back.

3. All audio interfaces can ONLY operate at one sample rate at a time - they cannot accept multiple sample rates concurrently as you would know, so both items (BIAB and the Keybaord need to be both at 48)

I did think of a work around last night though, as it is only playback I might be able to get by with using MME (as PG music seem to still be in the dark ages with audio - no WDM and no WASAPI) and then use the laptop headphone out port, but this is a "sticky" solution at best.

As I see it there is no alternative, at this stage, other than to look at an alternative to BIAB.

I did try Realband as it will allow both devices to run at 48, BUT it is horrendously slow at loading realtracks. Certainly not acceptable for using live....

I cannot use the normal analogue L/R out of the keyboard (Kurzweil PC3) as they are quite "noisy" at stage levels, and I think you will understand what I mean by that . The sPdif gives me a really nice solid and noise free output....

Cheers
