alright. SO if you read this Wikipedia article ( http://en.wikipedia.org/wiki/Microtonal_music), it states that you can assign notes, including those outside of our Western 12 tones, to a midi note. Can you guys tell me how exactly to do this?
It's all done with Pitch Bend. However, you have to set up Pitch Bend to operate correctly.
I suggest you set up PB to the value 1 in your instrument, which is a semitone up and a semitone down. If you're using the EXS24, for example, this is on the main EXS24 window at the bottom of the second panel.
Once you've done that, determine the level of PB that you want to apply. The following will give you an ascending microtonal scale:
Likewise, if you want to play something a quartertone flat, use PB: 0 32. The first PB figure (always 0 in my example above) allows ultrafine tuning. To see how the two figures interact, look at the Length/Info fields in the Event Editor.
One thing, though. Please remember that PB applies to the whole of a MIDI channel so, if you want a chord with different microtuning levels applied to different notes, then you need to use different MIDI channels or multiple tracks. Likewise, if you have multiple melodies, best to put them on different Logic tracks so that you can manipulate them independently.
Another way that might help is to use some of the 'exotic' tunings that are available for synths in Logic. These range from very subtle, eg Hermode tuning, to outrageously odd. I can't remember which ones give the wildest results, but try some of the Tibetan, Balinese & Old Chinese systems.
