• Speech

I made a simple speech synthesis plugin. It uses Microsoft's Speech API, so you'll need the SAPI SDK installed.

C# Sources.
Also have a look at Microsoft's TTS XML tutorial.

• RegExpr (String Advanced), by vux, was modified a little by me in rev. 4674 (up-to-date sources).

• AsAscii (String Hex)

• Stanton SCS3 (Devices MIDI)
• OSCLearn (Network). This is now my preferred way to use FingerPlayMIDI with vvvv
• Fingerplay (deprecated)

I made a module for FingerplayMIDI. kalle helped me a great deal with an advanced version - thanks :)
After adding sensor support to Fingerplay, I updated the module once more. Note that Fingerplay now support custom layouts. This module was built only with the default layout in mind (I don't know if there is currently a way to find out about the current layout on the server side...).

• Bit (Value Advanced). A little different from Bit (Value) that ships with vvvv - it takes the number and the amount of bits to use for encoding as arguments, which is more intuitive imho. Also works better with spreads.

• Metronom (Animation). Slightly modified from the one in the vvvv release (added period outputs).

• URLEncode (String) Encodes strings for URLs/POST data etc.

• Logitech Dual Action (Devices) Interface module for the Logitech Dual Action gamepad.
