Re: Nested sequences/non-linear writing possible in Logic? Topic is solved

Besides Ableton Live, you might also want to look at Bitwig Studio (created by some ex-Ableton folks I believe). I think Bitwig Studio has more MIDI devices, and maybe finer control of modulation/MIDI parameters. If I recall correctly, at least in Ableton Live, while you are selecting clips to play ...

Re: Is Mbox 2 compatible with Logic Pro?

I think I recall that the original Mbox (1) just worked as is with Core Audio, but after that the design changed so that was not the case. So as David says, I think you would need some kind of driver for Mbox 2 or later.

Re: How transmit MIDI clock from middle of project?

There should be a way to select transmitting MIDI song position pointer out from Logic, which I think will work as a jam/sync of sorts for MIDI, if you send it to an external sequencer. Or you should be able to start playback form anywhere and the external sequencer(s) will chase (assuming they work...

Re: How does logic handle CPU? Cores vs clock speed?

We've been using Mac clones for years with Logic. We don't typically use huge sample libraries, and so don't need to load large amounts of audio into memory for virtual instrument managers like Kontakt (though we do use some virtual instruments). One machine configuration is: 3.5GHz Core I7 (4 physi...

Re: Can't enter a note length longer than 999 bars?

If you know how long your piece is going to be in minutes, then you could use a tempo to time calculator like this one, https://toolstud.io/music/bpm.php?bpm=90&bpm_unit=4%2F4&measures=999 to calculate the tempo that will get you to the length of time you want. I put in 999 measures at a tem...

Re: External Instrument - MIDI Latency issue

Sometimes a diagram can help explain things. These are from "Logic Pro X - The Details" by Edgar Rothermich. I think his docs have been mentioned before elsewhere in the forums. It's interesting to note the choice for an external MIDI instrument where you use both the MIDI channel strip (f...

Re: Macbook Air fan going crazy

I would check your disk activity as well as the fan running could be from constant disk activity. This can be caused by applications frequently caching information to disk, e.g., when you have many tabs open in a web browser, and the browser is caching information for each tab to keep it up to date ...

Re: Current external SSD vs HD speeds for LPX assets

I would try to buy an SSD that says it supports SMART software utility - which can warn you when the drive is starting to have errors; I don't think all SSD's support SMART. My impression is that Logic is still happier with the OS one one drive and then media files on another drive (regardless of wh...

Re: Does Normalizing affect sound quality?

As previous poster(s) mentioned, normalization to 0 dB means you have to deal with inter-sample peaks; it's bad gain staging, and there's really no reason to make another copy/bounce of a file normalized to 0 dB.  Playing back audio normalized to 0 dbFS can add distortion and so the general rule of ...

Re: Logic 10.3.2 or 10.2.4 for old macbook pro?

You should try maxing out the audio buffer (I forget now if the max is 1024) - if you have not already done so. But that will also increase latency which could be an issue if you are trying to do simultaneous playback and recording. Under Applications -> Utilities is the "Activity Monitor"...

Re: Summing stack and external midi device?

If tracks output audio, then it should not matter if they contain references to audio or MIDI objects; it should work to create a summing stack containing them.  You should be able to create a summing stack that contains both audio and MIDI tracks (that output audio).  Selected virtual instrument tr...

Re: Summing stack and external midi device?

I ran into this as well.  I discovered that you first have to make MIDI tracks for internal virtual soft synths (should not matter what the instrument is), e.g., if you want to end up with 2 external synths in a summing stack, then first create 2 internal virtual soft synths, select those 2 tracks, ...

Happy to help.  Not sure this is of interest, but anything you can select in the event list from a MIDI region, e.g., click/highlight only the controller tab to display only  controller data, etc.  - can be copied and pasted at its original position to a different track.  So you can select only the ...

It reads like you getting a MIDI loop between the SX70 synth and the Karma software running on our machine?

I have not tried to do what you describe, but from what it reads like, I'm guessing that Logic app is taking some time to cache (read/write) info from all of the drum audio files, e.g., transient markers are being moved for all the locked tracks,  This apple tech note, https://support.apple.com/en-u...

Re: Midi output and input

I'm not sure what you are trying to do. I think of the IAC like another MIDI interface - but only in software - where you define MIDI busses so you can send MIDI to/from applications running on your computer.  With the IAC driver defined in Audio/Midi setup, you could create an IAC buss and, e.g., a...

Re: Is it possible that Logic support 32 bit audio samples in future?

I think Logic's freeze files are stored in 32 bit float format.  I suspect they are in the project folder, but I've never tried copying them out and importing them into another DAW.  But there are different 32 bit floating point file formats, so it's not necessarily a good file interchange format be...

So it's great tha...
