I have been trying to get a Kyma sound to interpret after touch (or MIDI key pressure messages after the note attack for a held note).
I can see the after touch MIDI events are being received as I see "press" messages in the MIDI Event Log, these are different message to key down/velocity messages.
I have read the manuals and they mention that the MDI channel pressure is mapped to !ChannelPressure (aka after touch).
!ChannelPressure is also listed in the reserved words list:
https://kyma.symbolicsound.com/qa/2130/where-can-i-find-list-of-reserved-words-for-parameter-fields?show=2130#q2130.
However, when I use the variable as a parameter in a sound (for example in the "Frequency" box of a sample), the reserved word is not recognised and it appears as a literal variable on the VCS tableau when the sound is run - it then acts like a normal ad hoc variable.
I have seen a mention that !KeyVelocity is dynamic and runs for the life of a key press (
https://kyma.symbolicsound.com/qa/2528/mpe-channelpressure-polyphony?show=2528#q2528) however, I do not see this behaviour - modulating key pressure on a sustained note does not affect !KeyVelocity. !KeyVelocity works well for the initial attack of a note, but the sustain of the not seems unaffected by it.
I have tried to find an example of the use of !ChannelPressure in the Kyma examples but could not find one.
Have I missed something?
Any suggestions would be helpful. Thanks
