Topic: editing pedaling in logic

hello,

i'm wondering if someone with experience with logic could help me out.
there's something weird about how pianoteq handles pedal information.  if i record something in the standalone interface, and then import it into logic, i get 3 midi regions.  2 of them have nothing but pedal information.
this is not really a problem, as i just delete those extra 2, but i thought it might be related to this:

if i record within logic, and try to edit the sustain pedal info (orange line) in the piano roll, nothing changes.  for example, if i play something will full pedal, then drag the orange line from 127 down to 0, the playback still has pedal, even though the orange line shows no pedal. i asked over on the logic forum, and they could not help me. 

does anyone else have this problem or know what's going on?

i guess another way to put the question is:  how do i edit the pedaling in logic?

thanks.

Re: editing pedaling in logic

rjawad,

I work with Pianoteq in Logic all the time (and I do quite a lot of midi editing) and never encountered the problem you're describing. Have you checked if the pedal information which your controller keyboard sends out is being transmitted on the same midi-channel as the note information? If not, that would explain why the midifiles which you record into Pianoteq have their data on more than one track, and also why your attempts at editing the pedal information in Logic have thusfar proven unsuccessful.
The quickest way to check these things is: record a bit of playing in Logic, and then open the 'Event List' for the recorded sequence (or 'midi region'). All the data in the Event List should have the exact same midi-channel number. If they don't, you'll need to check the midi set-up of your controller keyboard and make sure that controller data -- such as sustain pedal information (which is midicontroller cc64) -- is being transmitted via the same midi-channel as the note-on / note-off data.

If the pedal information (cc64) happens on the same midi-channel as the note-on / note-off (and velocity) information, I really can't think of any reason why editing that data in Logic shouldn't work.

Re: editing pedaling in logic

Piet, you're right.  For a simple down up pedal, the info looks like this:
ch 1, ch 2, ch3, ch8, ch1, ch 2, ch3, ch8, etc.
it cycles through 1, 2, 3, and 8. 
all the notes are on ch 1.

so the problem is not with pianoteq or logic; i guess it's my keyboard.  is there a way to fix that?  currently i'm using a casio celviano ap620.  it has 3 built-in pedals.

Re: editing pedaling in logic

rjawad,

I'm not familiar with the Celviano, but I'm pretty sure there's an easy fix for this. (Quite surprised actually that it behaves the way it does, cause what you're describing is somewhat unusual.)
I just downloaded the manual of the Celviano to see what you need to do, but the document provides hardly any information. As manuals often tend to do. Maybe the 'Duet'-setting causes your Celviano to transmit midi in such a peculiar fashion? (Just guessing here ...)

Either way, you somehow have to edit the Celviano's midi configuration --- instructions on how to edit the system's settings begin at pag. 19 of the manual --- and make sure that it sends all its midi data over one channel only. Maybe a system reset, to restore the factory settings, might yield the desired results, because those settings, as described in the manual on pag. 23, appear to be OK, as far as I can tell.

Sorry I can't be of any more help.
