Hi every body....( As usual, please forgive my bad English)

I am a Logic user since version 2.4 which does not mean that I consider myself to be a guru, but I have made some decent music with it
Once said that, what is happening is weird...
I record a part, a bass line for instance, and when I go to "piano roll" in order to edit it, change some notes or whatever, I found that all notes seems to be duplicated (one behind the other, same velocity, same duration), then I have to go one by one to avoid that double note mysterious recording...
I really don´t know why I am doing this, nothing happens with the double notes (or I am not hearing it), but it is kind of annoying...

May be someone in the forum has or knows about a solution (shortcut) or key command that could be shared...??

Well, thanks in advance for your time and patience

well idk why it's happening...but i know how u can fix it...go to the piano roll, then select all the notes that have a duplicate then go to function>delete>duplicates and they should all go away......i think that's how u do it try it

Hey emgcarra- I had this problem I finally discovered that my keyboard M-Audio Keystaion Pro 88 has four zones that can send MIDI signals to Logic. The default position when I power it up is that two zones are active so I get the doubling up of every MIDI keystroke unless I remember to switch one off! Drove me mad for a while. Hope this helps you find a solution. Lantana

Well, Thank you guys....!

1. I´ve manage to delete them in piano roll....Thanks.

2. Yes, that other path sounds interesting...I am using an old Kurzweil S2000 as midi controller, and it has a lot of functions, so may be I´m doing
the same thing you did..."Telling Logic twice what it must do"....

I´ll try all your suggestions ...

Thanks again

Hi,emgcarra,

I've had the same problem which seems to be common with older midi controllers.I'm using an old Yamaha DX 7 as a midi controller and the way to fix this is to check the output of the controller and switch off the unwanted data {most midi controllers and synths have midi out data filters}.

Hope that helps,

Well, Thanks again.....

I guess I did it....Now I have a new challenge....I am using now more virtual instruments that I´ve could imagine....So, LATENCY arrives and
intent to stay for a log time... I decided to make some research and look for a PCIe Card to avoid that....No way, at least not under $3.000
(meaning good preamps and sound improvement leap...) which is a lot of money....So I ´ll keep my good old FW410 and start a new approach...
Making every virtual instrument as a real audio file, then try to play bass, guitar, and voice with tolerable latency and invite a new device to
the party...In this case a Summit Audio 2BA-221 which promise to do the same trick of the UA TwinFinity, but whit 2 channel set up and mixing capabilities of both signals...(and $170 less)...
Any thoughts ?

Just freeze the track to free up cpu, they can later be unfrozen for tweaking.

Exactly what machine do you have? I've yet to even tax my Mini after two years of use, sessions of 32-48 tracks no freezing needed.

Well, that´s a good question because I upgraded cpu last year to a MacPro 2.6 Xenon, etc....with 5 GB RAM and a second internal HD....
Just Logic, Waveburn, and a couple of utilities.... (just waiting for a 4 more GB pckg. to raise the ram ..).
I must be doing something wrong, because of this behavior.... I also use a 256 Bus and at this moment I am trying to figure out How can I
get that famous "hardware direct monitoring" in order to avoid latency.....I´ll keep reading and working to see what happens....

Thanks.

Hi folks. As I'm getting wierd behaviour from 8 I thought I'd ask for a bit of advice on this thread with my problem. I've literally just upgraded my Os from Tiger to Leopard on a pre Intel twin core G5 2.3 system. I've first of all encountered issues with the OS but the local tech centre has solved that.

Now I'm trying to get my copy of 8 which I just won on ebay to work. I've installed it ok but when I try to ope it I get the "Logic has quit unexpectedly" message. I'm running a Protools Mbox 2 as the interface if that helps.

Any advice would be appreciated.
