Converting Korg PA styles to Casio CKF format

Recommended Posts

Hi chaps,

After browsing this forums for several days since I got my CTK 6200 for two weeks so found that you can't really create a new rhythm from scratch  :huh: . My ideal instrument now would be CTK 7200 but I got a good deal on ebay for a few months used CTK 6200 for £100 delivered ;)

Yesterday, I was trying to convert the rhythms/styles from Korg PA series to the Casio CKF so that I could load this into my CTK 6200. My workflow is:

01. Convert Korg PA style to Yamaha PSR 630 (SSF 1 styles which is actually midi file SMF format 0). I used Style Works XT style converter.

02. Rename the converted file extension .STY to .MID

03. Open the MIDI file in your sequencer (I used Cakewalk Pro 9 - old but very easy to use. You could use Anvil Studio free or something you're familiar with)

04. Change the drum track(s) from Channel 9 to Channel 10

05. Change bass track to Channel 11

06. Tweaks tracks for Chord tracks 12 to 16 (***Issues see below)

07. Test by connecting to your keyboard and playing each part as you hear the actual out from the Keyboard. (I actually connect the keyboard and set midi output of sequencer to keyboard before even opening converted file)

08. Save the file of you're happy.

09. Launch Casio Rhythm converter (part of IDES suit for last generation keyboards such as CTK 900 etc.) and open the converted style MIDI file

10. Set the markers for Casio rhythm parts i.e. Intro, variation, ending, fill etc. according to what is marked in the midi file converted and marked for Yamaha style. The Rhythm converter needs the starting point and number of bars so actual sequence in the midi file doesn't matter as long as you specify the part correctly

11. Convert to CKF rhythm by menu option Convert to Pattern which will save as Casio CKF file

12. Copy to your SD card in the Casio specific folder

13. Now load the rhythm (CKF) file in your keyboard in one of the user styles slot.

14. Now play! and have fun!

*** Issues:

The Casio CKF file only support 5 tracks for auto-accompaniment rhythm

* Channel 10: Drum track

* Channel 11: Bass track

* Channel 12: Chord 1 track

* Channel 13: Chord 2 track

* Channel 14: Chord 3 track

But the new generation of keyboards (CTK 6000/6200/7000/7200) supports 8 tracks for a rhythm in new AC7 file format. Technically it supports:

* Channel 10 to 14 similar to CKF format plus 2 more channels

* Channel 15: Chord 4 track

* Channel 16: Chord 5 track

which is great news and it makes the new generation Casio to stand with Yamaha, Roland and Korg in terms of style track counts.

But right know I cannot utilise the track 15 and 16 due to stuck in the conversion from Midi to CKF. So I cannot transform the Korg PA styles to Casio rhythm completely and bound to exclude/ignore track 15 and 16.

What I need is SMF(MIDI) to AC7 converter which has not seen the light of the day yet.


Well, this is my journey so far. I think I am kind of happy because I have happily converted Korg PA series Progressive style and playing with the on my Casio 6200 but I would be more glad If I could completely reproduce the complete Korg rhythm for my keyboard


Any help/comments would be great!


I would share my converted Korg style with you guys soon for your feedback. ;)

Please find attached my first ever conversion from Korg PA 80 Factory Style: Progressive from Bank 5 to the Casio CKF format file. Please unzip the file and load the CKF in your keyboard.




Enjoy! And let me know how it sounds!


Thank you

Thanks, I've done alot of research about these file conversions and posted here about the  PX350 which plays ckf and ac7, I'll give this file a listen.




Do you have any experience of converting Midi to AC7?

Well, according to the CTK 6200 manual the auto-accompaniment supports 8-tracks :D


09 - Perc

10 - Drum

11 - Bass

12 - Chord 1

13 - Chord 2

14 - Chord 3

15 - Chord 4

16 - Chord 5


Which is exactly like Yamaha Style format and similar to Korg PA style. I have no experience of playing with Roland but I think it would be similar for there GW series arrangers specially Roland GW-8 which has one of the best auto-accompaniments in an arranger keyboard according to Roland and some reviews.

Here is an interesting thread showing some of the problems you've already solved but no .AC7 converters:




I do know that my PX350 automatically changes .CKF rhythms stored in the internal user memory slots (10 only not much) to AC7.  I don't know if this is true with the CTK or WK series.  I have found nothing so far in the US, European or Asian Casio websites that have software to directly work with .AC7 files. I'll keep looking.

Here is one more link that may be helpful. Tnicoson here at this forum contributed part of this other thread which describes converting a mid to a ckf and transferring it to the CTK,/WK with the IDES data manager as an AC7. Problem would still be losing the 2 extra channels you want to create from the mid to the ckf. I have also tried translating Korg and Roland styles with just about the same limitations as you've found. Obviously, there is no easy solution to this!

Yes !  The CTK/WK units are like the PX in that respect.  If you load a CKF rhythm file into one of their user memory slots, and then use the Data Manager to bring it back up to a PC, it comes back as an AC7 file.  I originally thought that the Data Manager software did the CKF-to-AC7 conversion, but now, I believe it may be the keyboard's operating system that does it.

Yes, tnicoson. You're absolutely right. The keyboard does the conversion and I have also seen earlier.


I think I am limited to utilise the following tracks on my CTK 6200 when using CKF for custom rhythms.


Track/Channel 9: Perc

Track/Channel 15: Chord 4

Track/Channel 16: Chord 5


But I have work around to spice up my custom rhythm which is to replace the missing part with one of existing rhythm's track. What I meant to say that I could assign channel 9 Perc track of keyboards existing rhythm to my custom rhythm where it is empty (because CKF does not support it).


I think I might need to upgrade to CTK 7200 so that I could do all on the keyboard with no or minimum interaction with sequencing software on the computer.

By the way... is it possible to do something like this and convert the tones (I mean the sounds) from a Korg (let's say a Korg PA50SD) to a Casio CTK7200? I would really love to have something like the Korg tone called Vox Legends in my Casio.

I have a Korg Pa 600, and a Casio CTK 4400. I wonder if any body has tried to convert ckf files to Korg styles?. All you have done is to convert korg styles to casio ckf, but how about ckf to Korg styles? You may have some ideas.

Ниже прилагается мой первый переход от Korg PA 80 Factory Стиль: Progressive из банка 5 в файл формата Casio CKF. Пожалуйста, распаковать файл и загрузить CKF в клавиатуре.




Наслаждайтесь! И дайте мне знать, как это звучит!
