I have been using two simple free online computer keyboard pianos http://virtualpiano.net/ and https://www.onlinepianist.com/virtual-piano but they are getting really boring to me (I used to play on a real keyboard with many instrument options). What is a good online source for one that also includes other instrument sounds, but specifically the cello and preferably other string instruments as well? It's ok if it's not free, I would just prefer it to be new user friendly. Whenever I look for downloads, from app stores, they seem either overly complicated(i.e. difficult to just dive in and play freely) or too basic with only a few keys. An ability for it to record and add layers would be really cool too, but I have yet to find one.
i was wondering the same thing but unfortunately i couldnt find any really simple websites like the ones you linked. i think you might be better off using a real electronic piano keyboard but maybe a small one that you can just connect to your pc/computer and atleast that way youll have the normal piano keys to press and not the computer keyboard.
Try Soundation. The cello is decent as online keyboard goes. You can also record multi tracks. https://soundation.com/studio
