• Is compatible with Mac OS 10.12 (Sierra) with Logic Pro 10.2.4 and the iMac (21.5 inch mid 2011)

  Is compatible with Mac OS 10.12 (Sierra) with Logic Pro 10.2.4 and the iMac (21.5 inch mid 2011)?  I contemplate moving to Sierra, but not if it comes into conflict with Logic Pro.  Can someone advise?

  Thank you!

  Matt

  It was reported a number of not being able to save or to new projects with the title of the Sierra.

  I would conclude some time if I were you, especially if everything is working well at the moment.

• Logic pro exporting is not midi

  I recently changed my Logic Pro X and can't find a way to export midi. The resulting files are empty.

  I read the docs and see that this is the same process as Logic Pro 9: select midi regions > export > selection as a MIDI file

  Someone at - it ideas?

  To keep track, it only applies to some Logic files - other travel very well.

• Piano MIDI pedals on logic pro problems

  the pedals of my piano yamaha arius, the right and the middle ones, produce a sound when connected to logic pro X. I can't pass that off, and it drives me crazy because I can not play with pedals, which sounds terrible depends on music. The right pedal produce a E and the middle one a d. and it its really strong. I need a way to configure them to work as they are supposed to! Thank you

  This looks like to me MIDI controller messages being modified in MIDI Note messages. (These message numbers of control pedal, 64-127 and 66-127, correspond to these notes, and the value down to a pedal is 127, which, for a note, would be the largest value for sound intensity). Unfortunately, this can have several causes. A simple thing to try is:

  

  But don't think it will work in your case, as I suspect that the messages are sent by your Yamaha like this, so you will have to consult its manual and maybe its forums to find out what parameters to change. I guess that the Yamaha has a direct USB connection and not a separate MIDI interface?

  In any case, to check that the messages are sent by your Yamaha, download this free app:

  Here is an example when I type my pedal support:

  

• How to replace the logic board MacBook Pro mid-2010

  I have a MacBook Pro 13-inch mid-2010. About once a week, monitors (one who is part of the laptop) and an external will turn grey and freeze. When I turned off the computer, it brings back me to the login screen (I'm under 10.11.5), but I can't move the pointer (whether with my Apple Wireless Mouse or trackpad) to select the icon for my login. After a few reboots, the computer takes care of the password reset function. And there, I can reuse the mouse, select Restart the machine, and I'm back on my way.

  The genius of Apple and I suspect that the problem is with the logic board. Unfortunately, Apple has more parts for MacBook Pro mid-2010. I contacted a few service centers certified Apple the kind told me; None of them can help either.

  Any suggestions for how I have a fix for this problem? Thank you!

  You could contact a specialist to see what their requirement is to send you the

  computer while for a diagnosis appropriate; a specialist is the one who can do all the

  works internally and could actually fix the edge logic that the Mac came with.

  I know some who do this; they charge more than a parts Exchange hosting.

  You can see what a company such as wegenermedia can do. Or see what the

  iFixit guide for Mac (for your specific model) said repair and watch to see who

  part numbers are involved in replacement of the like-kind in refurbished or tested

  OK, from sources such as powerbookmedic.com and other sources used parts.

  The logic board may not be a problem; might be some on the Board of directors or of one which

  attached to, such as the graphics processor. These older models are not

  so difficult for a specialist expert set. While the Mac is able to do so, is a good time

  for they provide labour expertise to swap upgrade replacement parts.

  They can test the feature set and should provide a guarantee for employment.

  Some of these companies repairs also restored the supply of older computers they fixed.

  Good luck & happy computing!

• I don't hear Roland 501 Piano during playback when recorded in Logic Pro.

  When I record my 501 Piano from Roland in Logic Pro, I do not have the piano through my speakers to read.

  Create an external midi track

  in the way - (port) Inspector to ensure that Roland is selected and all midi channel.

  When you reproduce the track it is routed to the 501.

  If you don't hear it - make sure that Roland is configured to accept midi in reading

• How to assign to the logic of distance in a separate in Logic Pro environment physical port entrance

  Is it possible to assign the logical KEYBOARD with a separate entrance in the port of entry of environmental Logic Pro physics?

  Thank you for your advice.

  I don't think so.  Logic of distance is considered to be a controller. Controller input data stream are made (by logic) before stopping the logic entry in physics. I "think" (I'm not an expert on remote logic) that the flow of midi is available on the port of the sum.

  I'm still not aware that you can change the channel of the South on the logic of distance. So it must be channel a (connected) and your other controllers must be able to have their midi outputs assign other channels if you demux their output.

  (please, correct me if this is not correct about the logic of distance - more conjecture on my part because I use remote logical not)

• Keyboard in Logic Pro making strange noise

  Recently, I figured out how to use an audio interface for Logic Pro X so that I can record MIDI and hear me during the recording, but the sound I hear is very strange. When I'm not recording, the regular Steinway Piano preset sounds as it contains some very slow tremolo, making some notes sound an octave higher sometimes. However, when I save, the sound plays back perfectly normal. Anyone know how to fix this?

  Data sheet:

  Roland RD - 800 keyboard

  Interface Audio EX Roland Duo-Capture

  Maybe the RD-800 sends on two or more MIDI channels at the same time. To do this, simply save a note and take a look at the Publisher of the event, how many events is recorded.

  Best,

  DaCaptain

• Freezing / sluggish: Logic Pro 9. Mac Pro; Yosemite

  As the title suggests, I am experiencing sluggish controls and performance in reading with Logic Pro.  My specs are:

  Mac Pro (round) mid-2010; 2.8 GHz Quad Core (Intel); 12 GB OF RAM

  10.10.5 Yosemite

  Logic Pro 9.1.8

  Everything is apparently fine with the performance, however, I randomly and almost inevitably experience the app 'snap '.

  Never quite completely, it freezes, will get rather unresponsive in functions such as when I'm in the reading, he will just continue to play while any activated button will be delayed for a few seconds until the number of seconds before he answers.  This does not happen with the launch at the beginning of a session and a cool app, but wire time, it will be unless I have close / restart the application.

  I recently created a new installation of Yosemite on his own internal drive - using a stock of Apple HD (Western Digital, Black Label, 1 TB, 7200 RPM)

  The only thing installed on the OS drive is Logic Pro and a few plug-ins.  I watch performance monitors, nothing appears close to overload (this is both logic and Universal Audio monitors CPU usage).  My sessions are not complicated: consist on average of about 4-5 stereo Audio tracks / track Instrument 1-2 / 2-4 Bus titles.  Plug-ins averaged around 2-4 per track.

  I use a writing another drive internal (2 TB) and save the files of session while recording / mixing.  My plan was to spend the end sessions at the coast by car after completing their but I suspect that it is the source of performance problems.

  My question is, I'm pretty committed to get an upgrade of RAM max (32 GB for my system).  I hope that this will add enough buffer space to avoid blockages in the performance.

  • It is, 12 GB sound like a stretch to try to run the logic without any problems?

  • Would a 32 GB upgrade be important?

  • Logic Pro (9) have known problems with hang up and becomes unresponsive / slow over a period of time with a running period session continues?

  • Any other use?

  • Is it I better off working on and recording of current session to the local operating system drive rather than another drive?

  In fact... I think you will find that much of this is related to graphics performance. Are you running one of the EQS of channel mode Analyzer, medium or hi res? This will certainly lead to delays, even if they are not displayed. Logic 9 graphics routines is quite old and showing their age with newer operating systems. Using a dual monitor system (display)?

• matter of logic external midi instrument

  Hello

  MacBook pro connected via the usb Korg Triton rack interface.  Whenever I press a mouse click or key in the X one logic note random sounds of the triton.  Triton works very well isolated outside the logic, so I guess that each press of button in the logic sends a message for the Korg.  A way to disable this option in the logic?  Thank you.

  It's either a controller or a problem with the MIDI Interface configuration problem.

  Menu of Logic Pro upper left, then Preferences and control Surfaces, then work around all the controls.

  If your MIDI Interface looks like this: (only he could be the problem, they do not work on modern systems)

  You have the MacBookPro6, 2 - the Edsel of Mac. There may be the failure of logic-board that was covered by a recall program that is now complete.

  The model was abandoned in February 2011. It is now classified by Apple as a "vintage product." This means that Apple will probably refuse to fix (see exceptions on the linked page.) In this case, you will need to go to an independent service provider. The part can be is no longer available, or the repair may not be profitable.

  Often, the problems start after an upgrade of the OS. If the upgrade has been recently, and you have backups, you can then go back to a previous version of OS X.

  Otherwise, an appointment of 'Genius' in an Apple Store, or switch to a different service provider authorized, to have the tested machine. The trial will be free to an Apple Store - unless Apple refuses to even look at the unit, as it could. Diagnoses of current equipment used by service providers don't detect the fault. There is a specific test for this number called "VST" (for "video system Test.") Ask for it. A "Failed" result means that the defect is present.

  If you decide to go to an independent service provider, be aware that the replacement part may also be faulty. Some owners reported that they went up to three replacement boards before you get one that worked. Don't expect any help from Apple if you have to pay several hundred dollars for an another bad logic board and that the supplier will be replace again.

  If you don't want to take that risk, or if you don't like the price you quoted, you may (or may not) be able to work around the problem by disabling automatic switching graphics. To use the separate graphics processor, you will need a third-party utility to manually switch to him.

• Logic pro motu audio interface

  Someone has trouble with Motu 4pre after upgrade to El Capitan? I have no signal: alert the Motu 4pre in Logic Pro. All levels of finish on the CueMix interface return to 0 and all the channel input levels return to - inf dB regardless of what I do. I reinstalled the Motu software, but that did not work. Microphones operate and signals to inputs XLR 4pre seem to agree.

  You have the latest drivers for the 4pre?

  v1.6.68717 | February 11, 2016?

• M - Audio Keystation 49th, not its entry into Logic Pro 10.2.1

  Don't know what I do wrong here. I've lived all my Logic Pro X settings and I don't understand why there is no sound coming out of my M - Audio Keystation 49th in Logic Pro 10.2.1.

  Can someone tell me what setting could be the cause of the issue?

  

  (1) the keystation makes no noise... there just send data Midi...

  (2) download the free lunch monitor...

  https://www.Snoize.com/MIDIMonitor/

  Install and then press the keys on your 49th and see if it's midi notes transmittiing to your Mac...

  If it is not then the 49th doesn't correctly... and has nothing to do with logic... See the manual that came with the 59 E for assistance or call M-Audio for help...

  If it is... so that the midi data will be received by the logic so it must be how you have set things upwards in the logic itself... (As you have not selected the right inputs and outputs audio to hear sound from a software Instrument...)

• Logic pro 9 crashing

  Logic Pro 9.1.8 (1700.67) - OS X El Capitan 10.11.2

  Mac Pro mid-2012

  1. 3.2 GHz Quad-Core Intel Xeon

  14 GB 1066 MHz DDR3 ECC

  ATI Radeon HD 5770 1024 MB

  -------------------------------------------------------------

  So logical crashes constantly in two different circumstances...

  1: at some point in the project, I'll spend my screenset (with 1, 2 or 3 as the quick access keys) to get a different view to my project. When the screens are trying to change the two go black and about 3 seconds later I get a crash. After these accidents the project will be recorded as "hip-hop (crushed)." If some of my pieces have 10 + (crashed) behind the title.

  2: the other instance where I get a crash is when I'm doing my due diligence and randomly the CMD + s for a backup. Recording can run 5 to 25 times, but at some point it will say "the project «...» ' cannot be saved. "But right after that I'll save it and it will save perfectly. Only to then crash out of nowhere part 20-30 seconds later.

  I'm tired of dealing with this and I removed a lot of defective au. Run the diagnostic tests, etc.

  Here's the thing...

  Logic Pro 9 is not supported under El Capitan... Its considered to be an application of EOL (End Of Life) these days... so don't expect any patches or updates.

  Your choice is...

  (1) roll to a combination of OS X and previous LP9 that worked... using your backups...

  (2) updated Logic Pro x...

  That's all...

  Note: Partial copies of incident reports do not help possible all troubleshooting... like to much info is missing.

• Logic pro 10.2.1 update - Roland A49 controller has stopped working

  I've noticed since the Logic Pro update to the latest version this morning (10.2.1) that my MIDI keyboard/controller Roland A49 unresponsive.  Whenever I run the Logic Pro application I get this message

  Create MIDI keyboard assignments

  Please select "MIDI CH 1' on your keyboard of series of Roland."

  But despite the tent everything, including resetting my A49, reinstall the drivers, logic will not respond to the keyboard. The keyboard seems to work properly but in Garageband, it seems to be related only to Logic Pro.

  Anyone else have a similar problem with the Roland A49 or similar USB keyboard/controller?   Is there a solution?

  Thanks in advance,

  Simon

  I finally found a solution to this, it might be useful for others who have problems with their controller keyboards.
