you have to switch to tscript mode or use python.

well i tried but thats not helping…i switched the parameter to expression mode…i am seeing this video where this guy just types in the expression and boom it stars working

You probably watch a video where he is using 077. Since 088 python is the standard scripting language, so there is the extra step of switching to tscript if youd like to use tscript. Its that little python-logo button in the parameter dialog.

Btw. If you are just starting: rather go for python than tscript. Its the future

i get it now…shit i should`ve messed around a bit anyway thanx man…and yeah i am a beginner will keep your advice in mind. :slight_smile:

Here is a handy table of expressions in both Python and T-script

the python ones look longer (because they mostly are) compared to the terse t-script but python is a full-blown programming language whereas t-script was made more from csh and other old unix shell script tools. Python will take you much further.

t-script is still with us so we can bring in our old projects without having to completely rewrite all the old scripts. there are still a couple of obscure things that, to date, have yet to be translated into python - some MIDI stuff, for example, and telling a Kinect to move up and down etc.

but eventually, all will be python.me.thinks( :nerd: )

Latest version of the experimental has several MIDI send commands associated with the MIDI Out CHOP.
