Help please! Strange behaviour of Karma with key velocity

Post by Fener »

Hello,

I know I'm not frequently on this forum because I work also outside my country. Maybe my question has already an answer here, sorry for this.

I submit my problem.

I play Combi A117 : Radias XY Breakbeat Jam!.
I have a radias bass on ch4.
If I play without karma I have a dynamic (key velocity) on that bass, but when I switch on karma I can not have the same dynamic (when the bass is played by karma).
The strange thing is :
while karma is still playing (latched) if I select another bass for ch4 and then reselect the original one, immediately karma play the bass with a differeny key velocity (the one with which I pressed the key). Now if I switch off karma and on again I loose the dynamic (as the beginning).

In SEQ mode is possible to do this try better.

Enter in SEQ mode for Combi A117 (pressing Enter+Rec/Write).
Switch on karma and record some thing as you like, paying attention on the sound of the bass at track 4.
Now playback your recording and listen how the bass sounds different.
It seems that karma plays with a lower key velocity than the real one, but the karma "bass pattern" was recorded with the real key velocity of the keys.

Do someone of you encountered this behaviour?

Regards.

Marco.

Ok, I investigated it better.

It is very easy to try.
I have an M3 + EXB-Radias but can be tested also by those who do not have this EXB.

Take the Combi I-F48 : Radias XY Breakbeat Jam!
If you do not have EXB-RADIAS installed, take the I-A117 : Rad XY Breakbeat Jam! and select a bright bass on slot 4 to hear it better.

Enter in SEQ Recording by pressing ENTER+REC/WRITE.
Start recording and turn on KARMA.
Press just one key STRONGLY in the lower part of the keyboard to obtain a high ket velocity. This record just the bass pattern performed by KARMA.
Then stop recording, turn off KARMA and playback your recording.

Do you hear the difference of the bass sound between realtime and playback?
There is a key velocity change on that bass.
It seems that KARMA play the bass with a lower key velocity but records it with the real velocity with which you pressed the key.

Now, Turn on KARMA and playback your recording again.
No more differences on bass sound. Key velocity returns to be the one you was listening in realtime.

This has an explanation. I hope this is the right one.

KARMA has some parameters in the GEs RTP that controls the key velocity (accent) while you play, then the velocity sensing can be changed by KARMA (if it is enabled).

Actually, I was t thinking that the notes generated by KARMA, going to sequencer, are recorded as they are, with the same characteristics you hear in realtime.

Also, to obtain the same notes characteristics in playback like in realtime, KARMA must be turned on to "filter" them out.
So, it seems that the notes recorded in SEQ go back to KARMA module. This is new for me.

This behaviour is not a problem, maybe it as as expected.
Can anyone confirm this?

Regards.
Marco.

I can't try it right now but my experience with recording karma has been that the sequencer records exactly what you hear while you play. Playback should sound the same as long as karma is turned off during playback.

I think that if karma is on during playback the trigger notes are sent back into the karma engine again. What you would hear is a mix of the previously recorded karma performance and the live karma performace being re-trigged by the trigger track. But what you describe is that playback is ok when karma is on and that is the opposite of my understanding.

Is this something specific with just the Breakbeat Jam combi or do you hear similar behavior with other combis?

It's a filter cutoff issue. You can view the full answer at Karma-Lab: http://www.karma-lab.com/forum/showthread.php?t=19783
