Suggestions that Should be Considered

The only useful and easy to add thing here would be soloing instruments.

Adding a synth would be against the simplistic natute of the website that inspires creativity. Also it would probably be very hard on some people's computer. If you just want to try synthesizers there is a website that lets you play a synth in your browser.

Tempo changes are really not very useful. It is only really practical in those crappy piano versions of great classical songs. I feel few few people would actually use it and not very often.

Its helpful to not rely on the key guide. I think its pretty easy to see a key change in a song and hear it too. Adding a key guide change in a song is impractical also, every time you want the key to change you have to add a marker or whatever? We aren't writing scores for people,we are writing scores for a computer, who doesn't give two craps about what key the song is in.


Soloing instruments so only that instrument makes sound or muting instruments would be very helpful however

I disagree a little on your key guide and temp change, but do agree about how the synthesizer does decrease the amount of creativity. However, more options can mean more possible opportunities.
