Well cubase will record whatever you send to it, then you can send it somewhere.
Aftertouch can be used on some keyboards to trigger leslie effect etc. but that’s in the keyboard. If your keyboard does something like that it would work when you got the midi back from cubase, it would have the same aftertouch messages that you recorded.
Forgive me if I am wrong, but I am guessing that English isn’t your primary language, and therefore we are trying to “guess” a little at the question you are actually asking…
Are you in fact asking if the aftertouch that your keyboard transmits can be converted into some other MIDI controller data that can be used by Retrologue? (even though Retrologue can indeed respond to aftertouch… it is available as one of the Sources in the Modulation Matrix).
Anyways, if you have the “full” version of Cubase (as opposed to Cubase Elements etc.), you can use the Input Transformer to transform aftertouch into, say, CC#1 (modulation).
If that is indeed what your question was ( ), then we can eventually show you how to set that up .
OR (after taking a 2nd guess at the meaning of your question… sorry )…
Are you expecting Aftertouch to act as what certain organs refer to as “Second Touch”? (whereby, having pressed a note down to its initial stop position, you can then press it down still further, and it then send out a second “note-on” data).
the answer to that one is… no. (that is not what MIDI aftertouch does… and if you were under that misapprehension, then I really do advise you to read up on how MIDI aftertouch actually works… it is intended only for adding modulation (to the filter, volume, or vibrato etc.) to the notes that are currently being held down. (as i mentioned in the first part of my reply )
