Audio out via USB not working as expected

[rockstar898]

My Kronos 88 is connected via USB to my iMac running OS X 10.7.3 after I installed the Korg USB driver v1.1.1 (r1). I have the System Preferences / Sound / Input set to KRONOS and the Output set to my Presonus FireStudio Project.

MIDI notes are getting sent via the USB cable because I also have the Korg Legacy Collection and can play (and hear) the M1 virtual keyboard via MIDI with my KRONOS. I also see sound in the "Input Level" meter of the Preferences / Input screen on my iMac moving when I play notes on the KRONOS, but I don't hear any sound.

What's stranger still, is if I launch Logic 9.1.6 and record a simple external MIDI instrument track via the KRONOS, the MIDI notes appear in the piano roll, and I can bounce that to an audio track just fine (although I can't hear anything while playing/capturing the audio from MIDI). But after creating the audio track from the MIDI bounce, I can hear the audio track just fine.

Is there some setting on the KRONOS that I'm missing, or is this a problem with OS X? I'm wondering if there is some type of conflict between the Korg USB driver and the Presonus FireStudio drivers or something. If I use standard TRS 1/4" cables out of L/R analog from KRONOS to FireStudio to Mac, everything works fine, but I'd really like to get the USB audio working if anyone can assist.

Thanks!

do you use the Kronos for Audio Output?
If yes, you have to go to Global Mode --> Audio --> and you have to check the both Audio-Inputs to USB.
Otherwise I don't know, as I do not have OS.

Edit: Sorry, I just read that you use your Fire.. for Output.

So my way is just for testing, where the problem is. Use it, to test, if your problem is with OS or your Fire...

Thanks, but no, I'm not using the KRONOS for audio input. Setting the USB inputs doesn't make any difference. I really think this problem resides in OS X with the Korg USB driver or something, since I can record audio (without being able to hear it) and then listen back (and hear the recorded audio track).

So it's like the KRONOS is sending the audio out via the USB cable, but the computer won't route it to the speakers in real time. Only on playback of recorded audio tracks, which are essentially .aiff files on the Mac at that point.

[rockstar898]

This is definitely a problem on the Mac and not the KRONOS. I also set my Roland V-Synth GT to output audio via USB and selected it as the audio input source in Mac preferences, and can see the input level bar move when I press keys, but there's no sound.

So weird. Does anyone have any experience with USB audio input via Mac OS X 10.7.3 Lion? I'd really like to use both my V-Synth and KRONOS with Logic via USB versus having MIDI and analog TRS cables connected through the FireStudio, as I believe I can get higher audio quality in my recordings via USB.

I still have a few months of AppleCare left on my new iMac so I guess it's time to call Apple...

Thanks!

It's been years since I've played around with any DAW, and never in a Mac or with Logic, so I'm taking a shot in the dark here...

As I understand your problem, you can record the Kronos on the Mac, and hear the playback, but can't hear the Kronos live through the Mac. That sounds like a switch setting somewhere related to Monitoring. Often, you want the live sound to be muted during recording sessions to avoid feedback. Maybe you could poke around on the Mac and enable live monitoring?

Although I use Reaper and Pro-Tools, when this occurs to me it is that "monitoring" is switched off. Check that out in your system and I think your problem will be solved.

hi there,

I also use a Mac/Logic 9 and have had real headaches getting audio and midi running properly on the Kronos, my post also had responses from people telling me to adjust USB audio inputs (wtf..) when I was clearly looking for answers on USB audio output, the reality is some people here don't like to say 'I don't know', oh yes and a mod started complaining that I was confusing things because I mentioned audio and midi in the same post, unfortunately 'mr organised' didn't have any answers to my problem(s), and neither do Korg UK tech support, they just copped out with 'its your mac' haha what a joke, I gave up in the end, I'm now using the optical output of the Kronos direct into my console, it's ok but being limited to 48kHz is a ballache, however its the only way I can really get any real use currently (when I bought it, I was under the impression this was designed for pro application), The bottom line is this, if Korg can't help without blaming your mac setup, then it can't be done (currently) And just for the record, every single piece of equipment I've ever connected to my mac pro has worked seamlessly, the only thing that hasn't is the Kronos, I deal regularly with multiple device firewire setups, creating aggregate devices etc etc, the lack of connectivity between Kronos and Mac is currently a massive oversight on Korgs part, and I'm massively dissapointed.

Before blaming people, read the posts: Rockstar wrote: I have the System Preferences / Sound / Input set to KRONOS and the Output set to my Presonus FireStudio Project --> no word about Midi.

Your post is still below any "I don't know anything but I try to help" posts.
You did not even try to help Rockstar..you just want to blame Korg.
That is just a waste of space on the server...

And he also wrote: I also set my Roland V-Synth GT to output audio via USB and selected it as the audio input source in Mac preferences, and can see the input level bar move when I press keys, but there's no sound.

So, it is not a problem of the Kronos...

I can understand Korg. It is not their fault, that Mr. Inevermakeanyfaults is not able to have a running system. read nitecrawlers comment, perhaps it solves your problem...of course it will not...
strange, that many Mac users don't have any problems.

And if that Forum doesn't help you, it is your descission to leave.

by the way, if you use the Kronos for Audio-Output, you need the USB-Inputs...but as I already wrote, I did not read, that Rockstar is using his Fire...for output.

@Rockstar, I hope you get your problem solved very soon....perhaps it is also the solution for vortexian, but I am pretty sure, he will not tell us...

Thanks, nitecrawler! Duh, I didn't even think about that. Simply starting Logic and selecting the Preferences / Audio / Input Monitoring checkbox, and I'm good to go on both keyboards.

It's amazing how something so simple can cause such frustration LOL
@Laste7 - you are spot on about vortexian. I consider myself a fairly technical guy (I'm a technical sales engineer that builds cloud computing solutions for a global technology company), and posting questions to forums are my absolute last resort because it always seems that someone responds with unhelpful rants that take the thread way off topic!

Anyway, thanks for the tech support everyone... easy fix this time.

hey good one guys, now that you got both your midi and audio rolling across USB, wait for it to crash!, the problem your just about to experience is massive latency across midi every now and again (this wont effect external instruments, only the kronos), you can check the forum for a quick fix but don't start celebrating just yet ok?

[Laste7]

@vortexian:

Thanks again for a useless post.
I don't need you to worry about my problems.

btw. you should think about the reason, why your posts always leads to negative reactions.

[rockstar898]

@vortexian... maybe you need a faster machine. My brand new quad core 3.1GHz CPU, 16 GB RAM, 1TB HD 27" iMac has no latency issues whatsoever. I just recorded a 2 minute legato piano piece using 000:KRONOS German Grand via MIDI/Audio simultaneously, creating one MIDI track and one Audio track in Logic, with no latency, noises, or audio crashes whatsoever. Other than forgetting to check the Input Monitoring box in the audio preferences, I've had no issues, and I've got the full Korg Legacy Digital Collection set of AU plugins running simultaneously with Logic, which is controlling both my VSynth and KRONOS via USB MIDI/Audio. My iMac is blazing fast, even with iTunes, MS Word 2011, and Chrome all running in the background and my youngest daughter AirPlay streaming an iTunes movie over WiFi to Apple TV2 in the living room from my iMac while I record!

Didn't your mom ever teach you not to say anything at all if you can't say something nice? LOL

I'm glad it worked out! Don't let the negative posters get to you. We get pretty used to them here. There are a lot of good folks around here to help.

Hey laste,


1) my post was really to direct the guy asking the question towards possibly using the optical outs as opposed to the USB audio interface because it worked for me, I also commented it was locked to 48kHz, it may have sounded like a moan because it was, Korg also could quite easily have used an ADAT optical interface to achieve the sorely missed multiple outputs. (its the difference between consumer and professional equipment)

2) your assuming everybody uses just 1 input interface on their computer (ie the Kronos) firstly, its only 2 channels, why would you use it as your primary interface? you wouldn't, so you'd possibly want several things connected to achieve live monitoring of all your sources, on a Mac, you need to create an aggregate device so all those items appear as a single interface. This is normally a simple and quick process if you know what your doing, the reality is, the Kronos, when added to this list doesn't work. There needs to be a new driver set, simples..

[rockstar898]

Well, he may be negative, but vortexian may be right about one thing. As I'm playing through my MIDI track in Logic, editing/quantizing what I just recorded in the piano roll editor, the KRONOS just stops sending audio out of the USB port. My Mac is no longer seeing audio signal at that point. Simply changing the program to another sound and back on the KRONOS fixes the issue.

There is no latency while it's working... It just eventually overloads(?) the KRONOS keyboard itself and it stops sending audio (MIDI notes continue to be received by Logic, even after audio cuts out). It's not big deal, although a little annoying, to cycle to a new patch and back, but unless there is some huge advantage to using audio through USB when the KRONOS editor and DAW plug-ins are released, I think I'll just continue to use standard MIDI cables and TRS 1/4" analog audio cables through my FireStudio...
