How does this sound for a plan:
Sounds good. Lets do it. Enough talk.
Let's channel some of this energy into writting the API.
It's not like it's a huge task. The core VST API is what... 17
files, the core AudioEffect class is 7 pages of code.
The VST API is two files (AEffect.h and AEffectX.h), possibly including
AEffEditor.hpp for the ERect struct (personally, I've patched our VST
SDK headers so that ERect is defined in AEffect.h to keep the interface
as clean as possible). AudioEffect.cpp is part of the SDK, and not the
API - it's entirely possible (and in some cases desirable) to build a
VST without using the AudioEffect class at all.
The VST API consists of only:-
- The entry point for a VST plug-in
- The definition of the audioMaster callback type.
- The definition of the AEffect struct
- The definition of about five (rather arbitrary) functions to which the
AEffect struct holds pointers - dispatcher, setparameter, getparameter,
process and processReplacing
- The dispatcher opcode enum for the AEffect dispatcher function
- The dispatcher opcode enum for the audioMasterCallback function
- A handful of simple data structures used as datatypes by the two
dispatchers - event-list, event, parameter-properties, pin-properties,
view-rectangle and a couple of others
- Specifications for calling conventions, byte order, struct member
alignment
- A set of (very much under-specified) rules as to call sequences,
allowed arguments, threading, CPU state and suchlike...
Cheers,
Angus.
