Pianu

Pianu is a completely free online piano instrument available at www.pianu.com
This instrument software lets you play the piano using your mouse by simply clicking on the desired keys.
But, you can also use your MIDI controller and play your parts, chords, and progressions very easily.
One key feature of Pianu is the fact that you do not need to install anything, because it runs as an online app, extremely fast.
It also has an option to show the note names so you can learn them faster, ideal for students and beginners.
Perhaps the most important key feature is the "song" mode, which basically shows you the score of your desired song, and lets you play along with it while you can visualize the keys of each chord.
This makes the learning process of music notation extremely simple because you associate the keys with the sound and the chord position, all at the same time.
If you are a more experienced player, you can switch to a "full piano" mode that will show 7 octaves so you can start practicing in your MIDI controller with both hands and read the full piano clef.
This last feature will basically let you change the key size of the instrument from a small size to full size, whenever you feel confident with this!
Unfortunately, it will not respond to velocity, since this is not a super high-end instrument like Native Instruments, but the workflow is easy and the quality is good.
Bottomline: If you want a free, online music instrument, that works fast and lightweight, Pianu is the answer.
Pro Tools First

Pro Tools First is the free version of the award-winning software Pro Tools developed by Avid, available on Mac OS systems.

Xpand! 2 serves as a sampler that contains up to four sound slots playing back at the same time, letting you create super deep and complex timbres.

Effects are also included in this program so you can shape the sound of the virtual instrument devices after the patch itself.
There are sounds that range from natural instruments such as violins and cellos to more complicated synthesized tones from FM synthesis and Wavetable virtual instruments.
