Thank you! We are looking at ways to overhaul our playback. For now, Premium and Learn users do have the one-line percussions option, and you can also get many of those sounds using other instruments. We have a complete guide to all percussion sounds here: https://notes.noteflight.com/playing-techniques-part-2-percussion/adrian.lim-klumpes commented
PLEASE PLEASE PLEASE add these! I am a Noteflight Learn teacher with 400+ students and the fact there is no tambourine, triangle or maraca leaves so many orchestral basics out!!
We do have timbales, and several other instruments that may not be so obvious. Please see this article for a complete explanation of our percussion setup. http://notes.noteflight.com/playing-techniques-and-how-to-notate-them/adrian.lim-klumpes commented
add maraca and/or shaker to Noteflight Learn
