Note duration is now counted as fraction of a whole note, as measured based on BPM check-in: 5a35ffdd27 user: spiffytech@gmail.com tags: tld
06:27
TLD now accepts ordering of movements. Also, fixed bug that caused all movements and instruments to play simultaneously. check-in: db1df2f460 user: spiffytech@gmail.com tags: tld
05:32
Now supports minor chords check-in: f02f66468f user: spiffytech@gmail.com tags: tld
00:07
Added support for top-down composition check-in: 7c7ce6adb8 user: spiffytech@gmail.com tags: tld

* Features [1/5]
- [X] Top-down composition
- [ ] Transition the melody between chords appropriately
- [ ] Set maximum song length
- [ ] Need to support all chord types
- [ ] Doesn't handle rest notes

* Bugs [3/5]
- [X] TLD resets clock for each movement
- [X] TLD doesn't accept an ordering for the movements
- [X] Doesn't handle minor chords    
- [ ] Calculated duration is absolute, not relative to BPM
- [ ] Chords don't respect octaves


* Structure [0/3]    
- [ ] Chords should be composed of Notes, not ordinary arrays
- [ ] Generate score with proper generation tools
- [ ] Store csound score lines with instruments
