synthmixerdemo

The SynthMixDemo application is a Core Audio demonstration example to show loading from a sound font, routing through an effects unit for pitch adjustment and mixing with a multi-channel mixer

Here is a graphical representation in the AU Graph for the SynthMixDemo:

AU Graph diagram

Features:

Two instruments loaded for the sound font file and routed to bus 1 and bus 2 inputs on the mixer
Each input bus independently selectable - either bus 1 or bus 2, or both
Instrument 2 (bus 2) goes through an effects unit that has a ui slider for the pitch adjustment. The pitch bend in this example is a 'semitone' (100 Cents) in either direction. So for the C note, the slider to full right will give a C# note and full left will give a B note. Note that the full range of adjustment the pitch shift effect allows is two octaves in either direction (+/- 2400 Cents).
Pitch adjustment on instrument 2 will not effect the note pitch of the notes on instrument 1 as instrument 1 does not go though the effects unit. This you can demonstrate by playing notes with both bus 1 and 2 on while applying a pitch adjustment
Multiple keyboard notes can be played at once
