I recently acquired a Scarlett 6i6 (after a long list of various interfaces, both USB and analog.) The Control software is relatively complex (to me at least.. not as much as the M-Audio, but the flexibility of routing options is daunting.)

What I am trying to accomplish is this.. I have a beloved external MIDI module (Ketron SD1000) which I would LIKE to use in conjunction with Real Tracks (or even some of the great Super MIDI tracks.) I eventually figured out how to setup the Focusrite Control to route the analog input of the SD1000 so I can hear it through the monitor headphones, or even output through my stereo amp.

Where I am getting stumped is being able to RECORD the mix to a .WAV file on my PC. Exacerbating the issue is the plethora of Sound devices I have available.

My motherboard (graphics card) includes Nvidia HDMI outs, as well as a Sound Blaster Recon 3Di (which offers me a "What U Hear" input and SPDIF output in BIAB Audi Settings.)

I also have the option of the Focusrite USB (input and output) where the choice of ports is handed over to the Focusrite ) which has 1/2 and 3/4 analog as well as SPDIF in and SPDIF out.

Once upon a time I used to use a program called iRecord (which still operates) to record "What You Hear." Currently I am able to get that to record the MIDI from the SD1000 OR the Real Tracks but never BOTH mixed (which I can hear on the monitor or stereo.)

I also have Audacity which I used to be able to use (once upon a time) with its Loopback feature, to record a mix of RealTracks and MIDI. I can no longer get THAT to work.

My machine is pretty fast, and I have no issues with latency using MME (I try to keep it simple.) Any attempts at WAS give me the dreaded -9998 error.

Anyone have experience with a combo like this? All suggestions appreciated.
