 ## Caveats and Limitations ##
 
-Before I wrote this, I didn't know much about VST or the OPL at a technical level. This is the first VST plugin I've written. The sample rate is locked at 44.1 kHz. In hindsight I would have implemented things a bit differently, but it all basically works, and is now reasonably well tested.

+One thing I have learned is that all VST hosts are not created equal. I only really work with Renoise. Your mileage may vary.

 ## How do I use it? ##
 
-Each instance of the plugin emulates an entire OPL chip, but polyphony is implemented by using a channel per note. Parameter changes applied to all channels. With this plugin, essentially you are just working with two operators.

+## What can it do? ##
 
-Percussion mode is now supported! This mode is not very well documented, even in the original Yamaha documentation. It works with the DOSBox emulator, but doesn't seem to work too well in the ZDoom emulator. Here are some tips on using it based on experimentation and looking at the DOSBox source code.

+SBI files are an instrument file format developed by Creative Labs back in the day for the Sound Blaster. Essentially they work as presets for this plugin. Just drag and drop them into the plugin window!

 ## How did you create the instrument programs? ##
 
 To figure out the parameters used by the original games, I just added a printf to the DOSBox OPL emulator, compiled DOSBox, ran the games, and captured their output as raw register writes with timestamps.
 
 I hacked together a Python script which parses the raw output, identifying unique instruments and outputting the parameter values.

 The VST was written using Juce, a cross-platform C++ library inspired by the Java JDK. Among other things, Juce provides a GUI for generating boilerplate for audio plugins.
