Why doesn't Casio publish an AC7 converter?


Recommended Posts

The AC7 format is really good for complex rhythms with 8 tracks and many kinds of parameters, but how to convert a certain MIDI file to an AC7 rhythm? I have made a lot of MIDI files to create CKFs and AC7s, but I haven't got a CTK-6xxx or a CTK-7xxx, so I can only make CKF rhythms with just 5 tracks. If Casio publishes an AC7 converter, it will be good for many Casio users.

Call me dense but what exactly is an AC7 file format and what is it good for?  What makes it any better, if at all, than a MIDI?

 

Is it proprietary and limited to a single brand of instrument?  Does it contain more info than a MIDI or MIDI type 2 file?

 

I only ask this because MIDI type 1 has proven to be an incredibly resilient and long lived file format which has outlived many supposedly "better" upstarts.

AC7 is a format of Casio RHYTHMS which is newer than CKF. It can be made up with 8 tracks instead of 5 of CKF. It's not a song file but might be able to be converted from MIDI.

The following file types (filename extensions) are used by the CTK/WK-6XXX/7XXX Arranger Workstations:

 

AC7   User Rhythm
TN7   User Tone
DB7   User Drawbar Organ Tone
DS7   User DSP settings
MPS   User Presets for pre-defined chord progressions
CMS   Songs (Song Sequencer)
RM7   Registrations
AL7   All User Data (back-ups)
 

On the older CTK/WK (3XXX / etc) units, the equivalent files all carried a .CKF Casio generic file distribution extension, but were

automatically extracted and converted to the following specific file types when loaded into User Memory:

 

Z00   User Rhythm

Z01   Registration

Z02   Song

Z03   Drum Sound with wave sample

Z04   Drawbar Organ Tone

Z05   Tone

Z06   Tone with wave sample

Z07   DSP Settings

Z08   Package file (any/all of the above)

Z09   All of the above (backups)

 

Once the above ZXX files had been extracted from the original .CKF files, they would also be accepted

directly into the keyboard's User Memory, on subsequent loads, without need for conversion.

 

The only files from the older models that are compatible with the newer units are the User Rhythm files.

The newer units will accept either .CKF or .Z00 User Rhythm files, but they are automatically converted

to the new AC7 format as they are loaded into User Memory and can be brought back up to a computer's

hard drive as AC7 files.  They can even convert/load .CKF or .Z00 Rhythm files to AC7 format directly from

an SD Card into the keyboard's User Memory, circumventing the need for a computer and the Data Manager

software, but in this case, loading can only be done one file at a time, where as the Data Manager software

allows for batch loading of multiple files.

If you do an Intro or an Ending on a minor chord and get the same basic melodic pattern as with a major chord, only with minor chord notes, then NO, there are not separate Intros or Endings for minor chords, but if you get an entirely different melodic pattern, then YES, there are separate Intros and Endings for minor chords.  On MOTL and TOTL Yamaha Arrangers, many of the rhythms (styles) have completely different melodic patterns for Intros/Endings for major/minor chords.  This is done, not by the main part of the rhythm (style), but rather by an integral sub-program within the style known as the CASM.  So far, I have not found any rhythms on the CTK/WK-6XXX/7XXX units that you could consider having different Intros/Endings for minor chords.  Yes, they play minor chord notes instead of major chord notes, but the basic melodic pattern is the same.  I do not know if these units have an equivalent to the Yamaha CASM or even have the capabilities of different Intros/Endings for minor chords, but then, I have not checked all of the rhythm patterns.  That would be a nice exercise for whiling away an otherwise boring rainy Sunday afternoon.

没想到G版也时常光顾这个论坛,我就不用英语了~~为什么不创造一个像雅马哈CASM那样的转换器呢?因为CASM是雅马哈电子琴所独有的一种类似于某种计算机语言的东西,它就像是节奏的汇编语言,卡西欧的CKF/AC7最基本的节奏构架是依托在SMF也就是Midi之上的,因此卡西欧的节奏转化只能通过midi数据的导入,但是也可以使用AC7输出,点击这里查看安东尼奥的那篇文章简介:http://casio.medivm.ru/casio_rhythm_converter_doc.html

Just in case no one reads Mandarin here's a Google Translation of the above.

 


 

I did not expect G version is also frequented this forum, I would not have English the ~ ~ Why not create a kind of converter like Yamaha CASM it? Because Yamaha keyboard CASM is a unique computer language similar to some things, it's like the rhythm of assembly language, Casio CKF / AC7 basic rhythm framework is relying upon in the Midi SMF, Therefore Casio rhythm converted only by importing midi data, but can also be used AC7 output, here's the article Antonio Profile:

Hello friend:
Google translation function is still very strong, the translation of the sentence in our Chinese people seems to be more accurate, of course, there will be some grammar mistakes. :)
