@ -11,28 +11,16 @@ if it is a 2-byte macro, read a dummy byte.
then read data.
## pattern data
## binary command stream
read sequentially.
read channel, command and values.
first byte determines what to read next:
if channel is 80 or higher, then it is a special command:
```
NVI..EEE
N: note
V: volume
I: instrument
EEE: effect count (0-7)
fb xx xx xx xx: set tick rate
fc xx xx: wait xxxx ticks
fd xx: wait xx ticks
fe: wait one tick
ff: stop
```
if you read 0, end of pattern.
otherwise read in following order:
1. note
2. volume
3. instrument
4. effect and effect value
then read number of rows until next value, minus 1.
