Tips on using portamento on VSTi |
 |
I thought folks maybe wanted a lazydog on how to use portamento with their fav VSTi. Usually you may set your VSTi to monophonic and all is a go, but sometimes you might want to trigger the portamentos on and off and maybe even set the time for completing the slide. So how do we go about?
Well here's the answer.
As can be read in Inges tutorial over VST there are those MIDI Continuous Controllers to fiddle with, and while this tip cover the portamento part, it can also be used generically on all other controllers.
First off, to use a MIDI CC we state it in the effect column by typing "CC".
Then in the effect parameter column you state any of these parameters:
The parameters in short:
41xx for trigging portamento ON and/or OFF
05xx for adjusting time of the slide
25xx same as 05xx only finer adjustments
Explanation of parameters:
To trigger portamento ON: CC 4140
To trigger it OFF: CC 4100
OFF is any number between 00..3F and ON is any number above 40 (..7F)
To adjust portamento time: CC 0540
Where 40 controlls speed and can be set between 00..7F
Or: CC 2510
For finer adjustments
Here's an example
| Code: |
C-2 1 == == CC 4140 <- Trigger portamento ON
=== == == CC 0540 <- Set portamento speed
E-2 1 == == == ==== <- Note to slide to
=== == == CC 4100 <- Don't forget to trigger OFF
|
That's it!
Hope you've found this tip useful. |

I tried to reproduce this example, but I dont get any result. Tried different VSti but none of them seem affected by the CC portamento commands.
If anyone has any tips I`d appreciate it.

try to go into the helpfile of the vst-plugin ( if there is any ) and find the CC nr. of the portamento ON and the portamento SPEED. They may be different from the ones described above...

Thanks for tip, I thought the CC commands were standardized.
It seems that very few VST comes with a list of CC codes - but I did try the Invader which comes with a list(As stated in the VST tutorial) But I couldnt get any result.
Apparently sending more or less random CC commands to the VST is not a good idea. Sending the command CC 8040 to Invader caused a serious system freeze.  |
