VST is a type of plug-in but there's also AUs, RTAS and other types. Most of the big companies make their plug-ins available in all the popular formats. Logic uses AUs to add third party plug ins. The effects and synths that come with Logic are built into the programme, so they're not really add ons and can't be used in other programmes.

Beginners may wish to skip this section - writable computed observables are fairly advanced and are not necessary in most situations
Normally, computed observables have a value that is computed from other observables and are therefore read-only. What may seem surprising, then, is that it is possible to make computed observables writable. You just need to supply your own callback function that does something sensible with written values.
You can use a writable computed observable exactly like a regular observable, with your own custom logic intercepting all reads and writes. Just like observables, you can write values to multiple observable or computed observable properties on a model object using chaining syntax. For example, myViewModel.fullName('Joe Smith').age(50).
Writable computed observables are a powerful feature with a wide range of possible uses.
Example 1: Decomposing user input
Going back to the classic “first name + last name = full name” example, you can turn things back-to-front: make the fullName computed observable writable, so that the user can directly edit the full name, and their supplied value will be parsed and mapped back to the underlying firstName and lastName observables. In this example, the write callback handles incoming values by splitting the incoming text into “firstName” and “lastName” components, and writing those values back to the underlying observables.

Source code: View model
This is the exact opposite of the Hello World example, in that here the first and last names are not editable, but the combined full name is editable.
The preceding view model code demonstrates the single parameter syntax for initializing computed observables. See the computed observable reference for the full list of available options.
Example 2: Selecting/deselecting all items
When presenting the user with a list of selectable items, it is often useful to include a method to select or deselect all of the items. This can be represented quite intuitively with a boolean value that represents whether all items are selected. When set to true it will select all items, and when set to false it will deselect them.

Example 3: A value converter
Sometimes you might want to represent a data point on the screen in a different format than its underlying storage. For example, you might want to store a price as a raw float value, but let the user edit it with a currency symbol and fixed number of decimal places. You can use a writable computed observable to represent the formatted price, mapping incoming values back to the underlying float value:
Source code: View
Source code: View model
Now, whenever the user enters a new price, the text box updates to show it formatted with the currency symbol and two decimal places, no matter what format they entered the value in. This gives a great user experience, because the user sees how the software has understood their data entry as a price. They know they can’t enter more than two decimal places, because if they try to, the additional decimal places are removed. Similarly, they can’t enter negative values, because the write callback strips off any minus sign.
Example 4: Filtering and validating user input
Example 1 showed how a writable computed observable can effectively filter its incoming data by choosing not to write certain values back to the underlying observables if they don’t meet some criteria. It ignored full name values that didn’t include a space.
Taking this a step further, you could also toggle an isValid flag depending on whether the latest input was satisfactory, and display a message in the UI accordingly. There’s an easier way of doing validation (explained below), but first consider the following example, which demonstrates the mechanism:
Source code: View
Source code: View model
Now, acceptedNumericValue will only ever contain numeric values, and any other values entered will trigger the appearance of a validation message instead of updating acceptedNumericValue.
Note: For such trivial requirements as validating that an input is numeric, this technique is overkill. It would be far easier just to use jQuery Validation and its number class on the <input> element. Knockout and jQuery Validation work together nicely, as demonstrated on the grid editor example. However, the preceding example demonstrates a more general mechanism for filtering and validating with custom logic to control what kind of user feedback appears, which may be of use if your scenario is more complex than jQuery Validation handles natively.
No matter what your skill level is, there is a way for you to make your own audio plugin.
In this article, I’ll be sharing multiple ways for you to start developing your own audio plugins in no time.
Ways to make a VST plugin:
Drag-And-Drop Plugin Makers
A plugin maker will take all, if not most, of the coding out of making an audio plugin. Synth makers are especially useful for prototyping.
Coding
Coding a plugin will involve downloading a special sdk for VST development. This is how all the big names in the audio plugin industry make their plugins.
If you want to learn how to develop any type of effect imaginable, I highly recommend this book. It teaches you how to develop plugins in C++ and comes with A TON of example code for professional plugins. It is written very well and makes a huge effort to stand out from the other programming books.
I believe the book is well worth the price. It’s the only resource you’ll ever need to learn how to code plugins.
You don’t even need a full understanding of c++! This book starts at the very beginning and works it’s way up to more advanced material. I’d rate this book a 10/10 any day!
At least give it a look and read some of it’s reviews. It is an extremely helpful resource.
If you are leaning more towards creating software instruments, this book might be more your speed.
It is by the exact same author, Will Pirkle, and offers a ton of great information for you to get started.
Synth Makers/Prototypers:
1. SynthEdit
This has to be the most well known program for creating audio plugins on the fly. It is a lot more simple to jump into than writing code and is very understandable.
Keep in mind there is no mac version.
You can export plugins so they run on mac just not use the SynthEdit program.
2. Flowstone
Flowstone was Formerly known as Synth Maker. Flowstone allows you to create a virtual synth visually and then add code to create more advanced plugins. What stands out with this plugin is the design and intuitiveness. There are many features to this software including the ability to “connect to the outside world”. That means that you can connect to external hardware including any usb device.
3. Reaktor 5
Reactor is an audio plugin that allows you to make audio plugins. Reaktor is almost like a giant plugin library within a plugin. Many producers use this as an easier way to publish quality synths instead of having to learn how to program synths all buy themselves.

Programming
Programming a synth, or plugin, will most likely be a very steep learning curve if you have never programmed before.
There are many different ways to code plugins. I will be sharing 4 different ways to get started.
The most popular way to code is with C++. Most plugins nowadays are coded that way.
Coding Plugins:
1. Using C++ and Visual studio
C++ is a language a lot of people choose to learn. It is used in most commercial software. It can be a bit tricky to learn so make sure you get the basics down before you try building a VST plugin with it.
2. Using Java:
I love Java because it is fairly simple to get into. Maybe it is just me, but when I started learning Java, it felt easier and more natural than other programming Languages.
3. Using Ruby:
Substring Plugin Vst Plugins
I have never used ruby, but I heard it was a really simplified programming language. I found out that there is an add-on for Ruby called Opaz-Plugdk. It allows the creation of vst plugins in Ruby. I couldn’t find too much info on this, but I’m sure if you dig deep enough you could find some helpful sites.
4. Using C++ in Xcode:
Substring Plugin Vst Download
This or Java is the way to go if you are on a mac. The information I found was once again from teragonaudio. They seem to have a lot of good info on plugin development, so defiantly check them out.
