Hi I've developped this external for windows last year, this emulate keystrokes, the result of ascii code depends on your hardware, it uses kbd_event API, but I believe the python script from previous messages that uses sendkey would be much better.
You will have to use messages like this:
[downkey 18, key 9, key 9, upkey 18( for alt+tab combination.
Use it at your own risk, good luck.

Here's one scenario i'd like to see:
- Pedal assigned [PgDn] keystroke within Liquid Media, which triggers
scene change 2. PD outputs letters A-Z, depending on either volume or pitch frequency ranges input from audio source (microphone into acoustic piano) 3. A given scene within Liquid Media would then interpret the PD-generated keystrokes and trigger image events based on letter key "depressed" by PD.
You'd have the ease of image generation (a la Powerpoint) with the speed and power of PD to map the sound of acoustic music. Just my newbie imagination going here.

The pedals basically operate as programmable usb keyboard extensions, where you can custom assign any keystroke to any pedal (up to 12). I'm hoping that by assigning a certain set of keys to the pedals and reserving the rest for PD to control that everything can simply work together, if PD can output keyboard letters/numbers. Everything would run from the same computer. Again, please forgive me if i sound completely ignorant regarding what's possible with PD... Many thanks again!

As far as getting that information from Pd to Liquid Media, that may be the tricky part. Your current pedals are sending keystrokes straight to Liquid Media. Do you know if there is a way to control Liquid Media via MIDI messages, or some sort of message sent via a socket connection (maybe OSC)? If so, then you might be able to use Pd to capture your pedal input and then combine that with the information from [fiddle~] and/or [bonk~] to send the appropriate information to Liquid Media. If the only way to control Liquid Media is through keystrokes, then you might need to write some software that intercepts the keystrokes from the pedals and changes them depending on what is going on in Pd. andy On Tue, Apr 29, 2008 at 12:18 PM, Hugh Sung <hughsung@gmail.com <mailto:hughsung@gmail.com>> wrote: > I'm using a presentation program called "Liquid Media", sort of like > Powerpoint on steroids.
