at the moment, Meiro has one tambourine bank available for download and usage, HOWEVER there are plans for a ukulele bank in the future (if possible). the sample was provided by radiopassiveboy on freesound.org. as the tambourine is a percussion instrument, it is strongly advised this bank is used as a beat rather than a melody, and kept at one pitch in the song. the recommended resampler the default UTAU resampler.
unfortunately, there is no current sample available to listen to :(
