Logic Pro Updated To Support Up To 36 Cores

Apple has updated Logic Pro to support the capabilities of the iMac Pro, tuned to support up to 36 cores.

Here’s what’s new in Logic Pro X 10.3.3:

New Features/Enhancements

  • Logic Pro X now supports up to 36 cores.
  • Sculpture and Amp Designer are now optimized for iMac Pro, and deliver up to 12 times the performance compared to previous versions.
  • Sculpture offers a new high-definition mode that provides higher string resolution.

In addition to the performance improvements, Apple has updated Logic Pro with a wide range of stability improvements and bug fixes:

Stability and Reliability

  • Loops, Channel Strip settings and other content are again available on Macs using APFS (Apple File System), and on which Logic 8 or Logic 9 had been installed prior to Logic Pro X.
  • Logic no longer quits unexpectedly:
    • Sometimes when user loops created in Logic Pro X 10.0.7 – 10.1.1 are dragged into the Tracks area.
    • When adjusting the left corner off a region in projects that contain an Environment Macro that includes a Sysex fader.
    • When the Enter key is pressed to start a bounce while the mouse is being used to adjust the start or end point of the bounce.
    • When the Tracks menu is selected while the Audio File Editor is open with no audio region loaded.
    • When Repeat Section is used on a region in an Electronic Drummer track.
    • When previewing audio in the Audio Bin after enabling Transient Editing in the Audio File Editor.
    • Sometimes when on a MacBook Pro with Touch Bar the Shift key is used to add to the region selection in the Tracks area where the Score window has focus.
    • When the Shift and Option keys are used while adjusting the length of notes in an independent Event List window.
    • Sometimes when inserting Program Change events into the Piano Roll in MIDI Draw view.
    • When right-clicking a line break in the Score.
    • When pressing OK to confirm a clef change in the Score.
    • Logic no longer sometimes hangs when the “Convert Sustain Pedal to Note Length” Score function is used.

Plug-ins

  • Sidechain detection is no longer delayed when the side chain source is a Software Instrument track in Live Mode.
  • Latency compensation now works reliability with plug-ins inserted as Dual Mono or Multichannel.
  • Amp Designer no longer sometimes changes gain unexpectedly after stopping or repositioning the Playhead.
  • Tracks that include MIDI plug-ins again play back when frozen.
  • Scripter now reliably transmits MIDI events on time in scripts that start with a Needs TimingInfo = true statement.
  • Software Instrument tracks that include a Scripter plug-in no longer sometimes reset the instrument to a default sound when the project is reloaded or the audio driver is relaunched.
  • Tracks using the EXS24 Coffee Shop Percussion or Latin Percussion instruments now play in sync when triggered by the Scripter “Drum Probability Sequencer” script.

Alchemy

  • Alchemy no longer fails to show its installed Library in certain very rare cases.

Editing

  • The Piano Roll now reliably shows velocity bars on notes the first time it is opened after recording MIDI into a new project.
  • The Piano Roll again shows MIDI notes as they are being recorded.
  • The length display of notes in the Event List is now reliably correct in projects that include time signature changes.
  • The Step Editor now updates immediately as notes are moved using the Finger Tool.
  • Vertical Auto-zoom again works correctly in the Audio Track Editor.
  • The keystroke combination to temporarily limit dragging to one direction in the Piano Roll again works as expected.
  • Roland U-110 synth modules no longer display a check sum error when an associated Sysex Fader in the Environment is adjusted.
  • It is again possible to create velocity ramps in MIDI Draw that maintain the existing relative values of note velocities.

Accessibility

  • It is again possible to modify the start and end time of a bounce using Voiceover
  • The VoiceOver cursor now reliably remains functional when shortening a region at all zoom levels.
  • Navigating into an open Take Folder with VoiceOver no longer causes a continuous system beep.
  • Switching from the Main Window Piano Roll to the Score with Voiceover no longer causes the editor to close.
  • Using the Shift key with the cursor with VoiceOver to adjust the granularity of movement while positioning the Playhead no longer causes a Logic is Busy alert or an unexpected hang.
  • Adjusting the loop length of a Drummer region with VoiceOver no longer causes the loop handle to sometimes jump unexpectedly to the next region in the track.

Score

  • There is no longer a large unexpected offset when inserting objects into the score in page mode in documents with multiple pages.
  • Brackets for Guide Accidentals in the Score are again visible as expected.

Track Alternatives

  • Packing regions into a folder no longer causes Track Alternatives on other tracks to disappear.
  • Hidden Track Alternatives that are packed into a Folder no longer display in the wrong position when viewed inside the Folder.

Export/Rendering

  • Bouncing a project while Logic is downloading content no longer sometimes results in bounced files with corrupted audio.
  • Mono tracks that contain Mono > Stereo plug-ins again playback as stereo after they are frozen.

Takes/Comping

  • Comping now works correctly when the “Select Tracks on Region Selection” preference is turned on.

Control Surfaces/MIDI Controllers

  • Waveform zoom again works as expected with Mackie C4 control surfaces.
  • Logic no longer displays an incorrect “Incompatible EuCon version” error with EuCon software version 3.7.

Movies

  • Movies now play back when the Show/Hide Movie command is used while the movie preview is closed in the Inspector.

General

  • MIDI settings for External Instruments that are saved as part of a Patch are now reliably maintained when the patch is reloaded.
  • Setting a Track Delay on an External MIDI track no longer sometimes affects the timing and note lengths of notes on other tracks.
  • The note overview of MIDI regions now updates immediately to reflect changes to the region content when Automation is visible.
  • Notes sent to External MIDI tracks no longer sometimes hang when using Rewind or Rewind by Division when there is a Track Delay set for the External Instrument track.
  • Custom icons now are reliably sorted into the correct order on Macs with APFS formatted drives.
  • Logic now successfully create project backups on macOS 10.13 High Sierra.
  • The Musical Grid now shows reliably when it is set as the secondary ruler.

10 thoughts on “Logic Pro Updated To Support Up To 36 Cores”

  1. Apple has really stepped up their game with the frequency of Logic updates. This is a drastic improvement over the dead air they delivered a few years ago.

    Besides the new iMac, this one’s an important update for everyone with High Sierra, and it appears to fix lots of stuff besides.

  2. Kind of ironic that APFS/macOS High Sierra broke Apple’s own Logic Pro – along with a lots of other apps. ;-/

    This is another reason why I’m putting off upgrading to High Sierra (though perhaps someone will figure out a workaround, such as running Logic from an HFS+ volume or something…)

    1. That is precisely the workaround – but perhaps this update takes care of the APFS issues … ?

      I have no reason to upgrade to High Sierra so I won’t until I have to.

  3. It seems to have the power to last a decade or more. But will the screen last that long and how much if it needs replacing? Doesn’t matter since there’s no way I could afford even a mid range spec model.

    1. Still have my 2013 iMac (Could be wrong on the year but its an older model) and the screen still works perfectly. It’s pretty slow now but i use it to watch youtube videos in my workout room. Never heard of anyone worrying about a malfunctioning screen but maybe its a thing. Apple builds pretty solid hardware.

    1. Sure, but your typical performance problem isn’t the master bus, but your 200+ tracks each with heavy FX and instruments, right?

      1. He’e referring to the fact that not all of the workload in any given app will automagically get spread across multiple cores. Generally, something like an entire audio track needs to stay on one core. So having one faster core is better than an infinite number of slower ones, in that and most other instances.

        So yeah, a machine like this will improve performance in some areas, and in others it will be completely unnoticeable. Don’t believe all the hype!

        1. That’s general computing knowledge. But to be fair to the Apple people: A typical usage pattern of a DAW with many tracks each having inserts and some virtual instruments, would definitely benefit from it. Based on the mixing console and multi-track paradigm, there’s nothing more attractive for audio developers to implement parallelism by multi-core algorithms than this. Apple does new hardware and optimises its software for it. Logic gets regularly free updates in the recent years. Not much to complain here imho.
