Double Notes in Logic Pro 9?

When I play 2 or more notes on my MIDI keyboard that is hooked up to my computer (logic pro) it plays a note when I let go of the 2 or more keys. This doesn't happen when I play one note! WHY? HOW DO I FIX THIS? I tried turning off local control that didn't work. My MIDI controller is a KR-11 Roland Piano.

MacBook Pro, Mac OS X (10.7.4)

Well, you won't hear the sounds from your KR-11 because we disconnected the Midi In cable....


Make sure you turn off Local Control off on the KR-11 and Leave it off when using the KR-11 with Logic... as that will cause double notes to sound (Local On will cause you will hear the note being sent directly from your keyboard to your sound engine inside your KR-11 and you will also hear the note being sent from your keyboard to Logic and then back to the sound engine in your KR-11) You can then reconnect the Midi cable back to the Midi in of your KR-11 and hear the sounds being played.


As for why you are seeing double notes recorded as Midi even with the Midi In on your KR-11 disconnected is a little odd however...


Have you tried changing presets on your KR-11 to make sure it happens when playing different presets or is it just one Preset that causes this? For example, make sure your KR-11 is not playing a layer or split sound preset.... (A Layer would give you two outgong notes possibly.. one for each layer being sounded)

No.. I think it is your KR-11 that is producing double notes because you are playing either a Layer or Split preset on it...


Did you check to make sure that was not the case?


You can test out Logic itself by disconnecting your KR-11 completely and then using Logic's built in musical keyboard to make sure it is not Logic that is generating double notes...


Create a Software Instrument track


Sel;ect that track.


Choose a Software Instrument from the browser


Press the Caps Lock Key


Play notes by pressing keys on your computer keyboard


If you only get single notes (pretty certain you will) then you know it's your KR-11 and either it's settings or the trype of preset you are playing on it... that is the cause of the problem...

Some of the presets on the KR-11 utilize two or more sounds at the same time and it could well be that the preset you are using is outputting two or more notes for every one you play be it in split mode or layer mode.


Try using different presets on the KR-11 and see if that changes things.... and also try playing notes together in just one part of the keyboard (to test for split mode issues)

Yes please... that will identify the midi notes and channels that are being sent


You say you can't use presets with Local Off.. Did you create an External Midi Instrument track in Logic to do?


Also...


When using a Software Instrument track... (so you are not listening to or using sounds from your KR11 and turning off Local Control..) selecting a software Inastrument... and playing on your Keyboard, do you get doubled notes in the Midi track you record?

Its interesting that both the 'echo' notes are playing at exactly 64 Vel... and yes, they are all on Midi Ch 1... It still looks like they are being generated by your keyboard for some unknown reason.


Anyhow, what happened when you changed presets? Did it make any difference?


Also, can you do another screen shot of exactly the same thing but this time click on the "Additional Info' button so we can see everything coming from your keyboard...


Also, can you double check your KR 11 is in "whole' mode and not in any other mode? (See section 6.2 of KR 11 user guide) and... make sure things like "Musical Intelligence" are turned off...
