Quick Question about sample rates

Hello fine gentlemen! I record in 48k. I have Reaper in 48K, I have my Behringer X32 in 48k. I just bought a Yamaha SPX 990 just for the Symphonic patch so I can run my bass guitar through it and get some crazy stereo chorus/modulatey goodness Unfortunately, the SPX 990 only runs in 44.1k. QUESTION 1: Am I gonna run into problems by recording the sound of my 44.1k SPX990 into my 48k interface and then into my 48k Reaper? Question 2: I know you always wanna get a DI when recording, so whats the best way for me to do this? I use a Countryman 85 DI, which has 3 jacks: "Inst", "Amp", and "Mic Output". My chain before the SPX990 was always: Bass guitar -->Countryman 85 instrument input -->Countryman 85 mic output --> X32 --> Reaper. So how do I get the sound of the SPX 990 and the sound of the bass DI into Reaper at the same time? Do I use the "Amp" as an output to the SPX990 and then use the Left and Right XLR outputs of the SPX 990 to go into two separate channels of my X32? This would give be 3 tracks of bass (Bass DI, SPX990 Left, and SPX990 Right) Heres a pic of the back of the SPX 990 Here's a pic of the Countryman Type 85 As always, any help would be GREATLY appreciated!!

Since you're making analog connections sample rates are not important. But the Yamaha is a line-level processor, right? If the Behringer has an effects send/return, that's the place for it.

If the SPX990 is to be connected digitally and it only runs at 44.1k, that will be your only option. Further, it very likely doesn't have the ability to sync to an external clock. (It's possible it may have the ability to sync to an incoming digital signal but don't assume.) If not, then it would have to be the clock master in the system when used as well. If the digital connection gives much cleaner signal than the analog inputs (as many digital fx units do that have somewhat lo grade AD/DA stages), you're just going to have to do that part of the work in 44.1k. Upsampling later on with SOX to put it back in your sample rate release format of choice shouldn't be a problem. (Or at least less of one than using the analog connections on the unit.) You might want to nose around online. Someone might have those SPX programs available to load in a plugin.

... and after all that the unit in question has no digital I/O?! Haha, well if this unit is analog only (which looks correct) then you won't be sending digital audio to it at ANY sample rate! The above advice would only apply to a unit with digital I/O. That the unit has internal AD/DA and processes digitally is what it is. It could be run by squirrels internally and your only connection choice would still be the analog I/O. Some people might compare the AD and DA converter quality in some of these devices to squirrels... Haven't the programs from most of these older fx units been liberated at this point as IR files?
