Jazz string bass pack that's in tune?

[Selek]

I'm trying to make piano-bass-drums and guitar-bass-drums jazz instrumentals using MIDI samples only. (I do play piano, guitar, and electric bass, but I've never played a string bass.) Every bass sample I try sounds a little sharp to me. I guess I can fix this with the detuner tools, but it sure would be easier if there were an out-of-the-box solution. Can anyone recommend a string bass pack suitable for jazz or classical that is in tune? Many thanks in advance.

This may not be what you want to hear, but you can send that midi bass clip to an audio clip and then record it as audio. From there use something like Melodyne and Tune it. It would take just a few minutes and you would have what you want.
