In the last tutorial, we created a 'smart' harmony maker - one that will take a monophonic source and generate harmonies based on a diatonic key. This is fine if you want each harmony voice to have the same sound or timbre, but that's not really that interesting. It's not how a real ensemble works. In a real horn section you have different instruments covering different parts. You may have  a trumpet on top, a bari sax on the bottom and some saxes and trombones filling out the middle. In a string section you'll have a bass on the bottom, violins on top and your cellos and violas filling out the middle voices.

We'll expand on the concepts introduced last time, and create a horn section that will stay in a diatonic key, and each voice will have it's own sound. Read on to dive in...

In this Reason project we will create a harmony maker, similar in functionality to the Digitech Vocalist series of harmony makers. The completed effect combinator will accept the audio output of any device and add up to three harmonies that track the key your are in. For example if you are playing in the key of C, you will hear a C major chord if you place a 'C', but an A minor chord if you play an 'A'. Ready? Read on to dive in.
