Using 2 or more USB instruments with Logic Pro

Question

I recently purchased a Korg M3 (which is great). I'm considering adding a Motif XS rack.. My question, are any Logic Users out there using Logic Pro with two or more USB instruments connected?
Are there any issues with that (other than assigning to different MIDI channels)? Does USB bog down when there is too much data?

Answer 1

I'm only using these three lines of code. If they don't work, neither will any more lines.
I discovered the issue thought. If I read two different fields from the same user-defined table then it works. If I read from two different user-defined tables I get the error. Apparently B1 can't handle parameters being set from two different ud tables.
This works:
DECLARE @S2 nvarchar(30), @S3 nvarchar(30)
SELECT @S2 = (SELECT T0.U_Country FROM [dbo].[@COUNTRIES] T0 WHERE T0.U_Country = '[%2]')
SELECT @S3 = (SELECT T0.U_CCode FROM [dbo].[@COUNTRIES] T0 WHERE T0.U_CCode = '[%3]')
While this does not:
DECLARE @S2 nvarchar(30), @S3 nvarchar(30)
SELECT @S2 = (SELECT T0.U_Country FROM [dbo].[@COUNTRIES] T0 WHERE T0.U_Country = '[%2]')
SELECT @S3 = (SELECT T0.U_AdCode FROM [dbo].[@BPGROUPS] T0 WHERE T0.U_AdCode = '[%3]')
