I've been sitting here trying to play turns quietly

I can't find the music, so assuming I'm playing the right stuff for the bit in question (is it the section where there are turns on consecutive notes rising up the scale???) but I suspect, after sitting here experiementing, that the mushiness is probably less to do with the fingering itself (there's not that much difference with an open C# especially when played quickly) but more to do with the cleanness or not of one's technique. I
think practising splurts or similar to get the fingering really smooth would probably solve the problem.
