Hello,
I'd be happy to record you quality solo violin. Unfortunately, I cannot record a violin of me performing, although I am a string player (both violin and viola) -- so my offer is to record a live, acoustic violin using a sample library. It is the sound of a real violin, played by a human performer, so it will sound realistic.
Please feel free to discuss with me. I can offer to send you a short sample of your track to see if you like the violin sound I can make.
Kind regards,
Yasas
