Boot up time.

JeffB63 · Post by **JeffB63** » Thu May 05, 2016 2:35 pm

Greetings on this beautiful sunny day.

I had an original Kronos some time ago but never dared use it live due to the long boot time.

I'm currently considering a new purchase and was wondering if the Kronos 2 boots any faster?

Slightly, but then it comes with new sample libraries (EXs17/18) which cause it to take about the same. I have both the Kronos 73 and Kronos 2 88 and they take roughly the same amount of time to book generally, depending on how many KSC's you're auto-loading.

We have tons of info about using a UPS unit here at the K Forum. For not a lot of $ power it up before the gig, and unless thing go really bad, no worries.

I have the original Kronos and have gigged with it since it first came out. I don't have any issues with the boot time. I let it boot while I'm plugging in cables and putting away cases. It takes me longer than 2 minutes to set up, so I'm good.

I love gigging, rehearsing, jamming and writing with the Kronos. It's been ideal for me to have my best sounds with me at all times, all in one keyboard. I miss it when I don't bring it.

The 2-min boot time is a very minor annoyance that doesn't matter when playing, and I really can't see that being any type of criteria when evaluating which keyboard to buy. A lot of the other pro synths out there these days aren't exactly instant-on either.

I usually use a UPS, and an often bring an additional keyboard as a weighted controller which is just a volume knob away from playing a piano sound should something unfortunate happen to the Kronos.

I have the Kronos 2, but, to tell the truth, I've never counted how long it takes to boot. Like LZ, I just know it takes me more time to setup cables, pedals and say hi to other musicians.

Indeed a lot of others new pro synths aren't instant-on either.

Unfortunately had a gig where the Kronos started freaking out. It kept choosing the same patch over and over driving me nuts. I finally rebooted it but I had another keyboard and played that one. In the end it wasn't the Kronos but you 2 minute time is long on stage.

You can reduce boot time considerably by choosing the Ksc you want to load on startup. You can do this by unchecking the boxes related to options in the auto-load ksc settings tab in global mode. Once started up, you can load the options.

I turn it on, pour a coffee, plug in my headphones, and it's ready. Maybe 90 seconds or a tad more. I can't imagine the boot time being an issue for anyone setting up to gig --- from my home experience.

Where the boot time would be an issue is if you had a power surge during a gig and had to restart in the middle of a session. That's why a ups is a good idea for gigging musicians.

You are forgetting another problem IF you have to restart during the gig due to a problem. Don't assume that you will never have to restart - it has happened several times for me.

I don't know why we are making excuses for a 2 1/2 minute boot time. No matter what, it is a long time - we all accept it, but it is a longer than almost every keyboard on the market.

I mean it's come to the point where now it's a requirement to have a UPS etc... which most of us never had to do with any other keyboard we ever owned. We accept it due to the Kronos being such a great machine - but we really do sound like we are ignoring reality saying that it's not an issue if we have to restart on the gig - which can happen at some point.

Highly suggest getting a UPS no matter what. This keyboard is power sensitive and will reboot at the slightest glitch in power. I have used them live for 5 years without incident. But always with a UPS. I got a lightweight one for about $75; will keep keyboard running for more than 30 minutes.

.

because it always takes ' time ' to load up large (gig's) samples on any device.

Yep, no argument from me. The boot up time is what it is. Whether the large samples are worth the load time is another topic.

I agree with aron. boot time is nothing when it's worth. for me I don't see any problem for booting up. we usually participates with the Battle of the Bands and one of the usual rules is there is the minimum setup time which is 3 mins. What I did is to put my KK into the stand, plug and switch on right away while I'm sorting my cables and pedal. without knowing it, it booted up successfully before our drummer finish setting up his cymbals.

Hi Guys

Thought I'd share this in case anyone else is in the same situation...
If you're doing a gig where you know exactly which sounds you're going to use, and you want to be super-safe and shave off as many seconds of boot time as possible in case the worse happens, then you can create your own KSC file to be loaded at boot up, so you only load the samples you need.
My Kronos X with OS 3.04 will boot in 1min34 with just the PRELOAD.KSC selected in the KSC Auto-Load tab in Global mode. If I uncheck the PRELOAD.KSC file and let the Kronos boot without loading any samples then it'll boot in 57 seconds! If you happen to be doing a gig using only the synth engines that don't require samples then lucky you, you're done and you have a super-fast boot time (relatively speaking).
If you are using programs or combis that require samples then do this to get a boot time somewhere in between 57 seconds and 1min 34...
First go to the KSC Auto-Load tab in Global mode, deselect all the KSCs including the PRELOAD.KSC one, then hit "Do Auto-Load Now". This unloads all of the samples so you're starting with a clean slate (don't worry you're not deleting anything, they're still on your hard disk). You should see the amount memory used for samples go down to zero. Next, go through your setlist (you've got your sounds in a setlist,right?) play a few notes on each patch, and if you get the message "Samples not loaded" at the top of the screen, go into Program or Combi mode (whichever the patch uses), and using the Page Menu (top right corner of screen) select "Load Required Samples". Make sure you select "Load only required samples" and not "Load complete banks". You don't need to save the program or combi, but if you do it won't hurt. Once you've been through your whole set loading only the samples you actually need, then you need to save that state as a KSC, so go to Disk mode, select the Save tab, navigate to wherever you'd like to save your file, then using the Page Menu (top right again) select "Save Sampling Data". Select "Links to EXs" or "Both sampling mode and Links" if you're using additional samples, give your file a name like "BeyonceGig"

and hit Save. Finally, go back to the KSC Auto-Load tab in Global mode and hit "Add KSC". Find the file you just made and hit "Add". Make sure that this new KSC is now the only one selected to be preloaded, wait ten seconds for the changes to be saved to disk, then switch your Kronos off and on again with your stopwatch at the ready. You don't need to save the settings you make on the KSC Auto Load page, they auto-save.
In my case, the Kronos now boots with all the samples I need in 1min 7secs, so I've saved myself almost half a minute of embarrassment if it all goes pear-shaped on the gig.
And make sure you use a UPS. Remember it ensures your power supply is consistent as well as guarding against complete loss of power. Before I got my UPS I did have one incident where the Kronos froze and I had to reboot, I suspect due to a surge or dip in power. Since I got the UPS it's been 100% reliable.
