Today i toyed with an acoustic piano and a clarinet
Added some delay and echo to the piano
Tuned the filter and eq to make the piano more present in the low
Added some more release to the envelope and made attack a bit slower
And then a tiny bit of wah wah..

And then added the clarinet at 50% volume..
And set it to mono.. and disabled damper pedal..
Added some chorus..

Worked very well..
In the end you can layer any sound this way,
Because what i did was actually creating a new sound..
