Does anyone know of a good irish tin whistle vst? I have been looking for one and I can't seem to find one. I have an irish tin whistle, so is there any way that I could record the notes and turn those into a vst?

Tin whistle isn't a very complicated instrument to play, so why not just record a performance, then edit out clumsy bits in an audio editor? Otherwise, just multi-sample it, trim etc the samples and use it with a VST sampler, there are plenty of good freeware ones (look up kvraudio.com database, for example)
