Code Snippets is a page where I will occasionally post useful Delphi sources related
to DSP, audio and VST programming. This is a great resource for anyone working in this field. Whether you're a programmer working during the day on party poker or other game sites, or you're working on a project in your spare time, this is invaluable. I will continue to update this page with the best information and examples of great coding.
 

If you want to store large data blocks inside the preset/bank files of your plugin
(eg. samples or tables), you should use the so-called "chunks" mode. This can be
somewhat tricky to handle and understand, so I wrote a little tutorial about how
to do this in Delphi. I did also include a little VST demo plugin with full source
code that allows you to store an image and a text as well as other parameters for
each preset of the bank separately.

IThis download includes 2 interesting Delphi components, developed together with
Christian Budde (www.savioursofsoul.de/Christian/):

- VSTHost is a component for loading and accessing a VST plugin from your Delphi
  programs. You can open the GUI, access the parameters, load and save banks
  and process audio blocks.
- ASIOHost is a component for accessing the ASIO driver of your system. It is really
  easy to configure and allows you fast access to the professional audio drivers.

Now think of combining those components: a VST plugin that is itself a host for
other VST plugins? A plugin that streams its audio to the ASIO outputs? An ASIO
host that loads and uses VST plugins? Everything is possible...

Also included in this download is:
- a little ASIO host demo
- a demo of the VST host in combination with my VST template to profile the
  performance of a plugin
- a unit for accessing the MIDI input and output ports of the operating system
- a unit for reading and playing back MIDI files.
- ASIOConvert: Christian Budde's excellent unit for converting audio data from
  one format to the other. This does now include extensive 3DNow and SSE
  optimisations!

This is a powerful step-sequencer class for Delphi, allowing multiple parameters per
step, optional interpolation between the steps and sample-accurate processing!
Download my Stepper and Screamer plugins to see (rather hear) the class in action!

This is a rather simple 303 emulation class that was partly converted from several old
C++ sources from the net and partly coded by me. Download my Screamer plugin to
hear how it performs!
