Lag in sequence mode - Recording on Korg Kronos

dagodoy · Post by **dagodoy** » Sat Jun 21, 2014 10:44 pm

Hi.
It just happens with sequences 100% done on Kronos from the beginning. After recording about 70 measures and 12 tracks (all MIDI notes and not Audio samples), the Kronos start failing with some lag time on operations. Let me show with an example:
- Measure 70. I press REC and then START. It begins with recording process.
- I press STOP and kronos freezes for 3 seconds and then goes normally.
- When I try to change to measure 80 (for example) I press 8-0-ENTER and it freezes for 3 seconds too.

This happens even when I press STOP and then STAR again just to hear what I recorded. I have to wait 3 seconds.

I wrote Korg support on USA and there was not any response from them. I sent the SNG file, a video file showing this lag issue and there was no response from Korg Tech Support.

I updated to 2.1.1 and same error occurred.

I have a friend with a Kronos 61 and he told me "I'm having this lag too!". We are working differents songs and we are not sharing the same SNG file.

If I load a MIDI file done in other keyboard with more than 100 measures and 12 MIDI tracks full of notes, it works flawless! I'm thinking this is an error on KRONOS sequencing process and not a general error.

Any ideas? Please help!

This lag always happens when my SNG has more than 70 or 80 measures with a lot of MIDI information. BUT if I mute some channels (3 or 4 of them)... the problem disappears!

One of the most times where This problem appears is when I stop recording and press START immediately to hear what I did (in a half of second time)... it freezes for 2 or 3 seconds (Even it doesn't play any sound when I press any key on the keybed)

If I write measure number and press ENTER, it changes after 2-3 seconds. When I press "Track Edit" Tab, it freezes for 1 second... this happens in any song. This didn't happen in my Triton TR. Shouldn't work flawless this machine?

Additional updates made in authorized centers: - Additional 160GB hard drive installed - Additional 1GB memory installed.
Operating system is 2.1.1

There are no attached accessories. Just a pedal but there are no changes if I disconnect it from the keyboard.

I've been holding back commenting on this because I was hoping someone with more knowledge would give an answer. I have noticed the lagging that you are talking about with one set of sequences. There were about 16 songs total and many had busy MIDI tracks. I eliminated the delay, but I'm not sure exactly what did it. If I remember, I thinned some of the MIDI data. It could be that actually saving your sequences will help.

My suspicion was that the delay was caused by a full edit buffer. Saving and reloading your sequence might give you a fresh, empty edit buffer and make the Kronos respond more quickly.

Then again, I could be completely off base.

Somewhere in a cobwebbed corner of my mind I remember issues being caused by a full edit buffer. It could have been an old onboard sequencer or even my early days with a Mac. The edit buffer is a place in memory where changes are stored so that you can undo if needed. Maybe an edit buffer isn't even a thing anymore in modern OSes, but I'm thinking that this solved the problem for me on the Kronos.

Thanks for reply.

This happens with just one song inside a SNG file and not a group of songs in a File. In fact, I always save the song after a few minutes of sequencing to avoid data lost for any power interruption.
This still happens when I power on the keyboard and load the SNG file immediately. Tried rebooting the keyboard to flush memory load but no luck

Any other suggestion?

Sorry, I got nothing. Hopefully, someone else can jump in...

SAVE, then go through deleting track by track until you find the track causing the problem. Usually in the Event Editor I'll find a s**t load of EXCL data in the offending track. Dump them all using "Erase Measure" with setting "Exclusive" instead of "All".

I REALLY wish we had a way to see exactly what the EXCL data is in the editor. Most of the time it makes no difference at all, or I can use an effect to achieve the same results.

Please, let me know your results!

DAMN I LOVE MY KORG!

Hi thanks for reply.

Do I need to do this in all newsequences on Korg?

This happens everytime I create a new song with many trakcs full of midi events (not EXCL or CTRL)

I haven't found this to be an issue very often, so I don't have an answer to that.
