Tools for creating AC7 rhythm files for Casio keyboards (especially CT-X keyboards)

ac7maker's Issues

Incomplete chord conversion tables

The CT-X keyboards recognizes chords (see User’s Guide, page 147 or A-2) that are not listed in the conversion tables file. Is there any reason why these are left out?

“f-root” conversion tables

There are currently 16 chord conversion tables in ac7maker.py; the 3 “f-root” tables documented on page 88 or EN-87 of the User’s Guide are missing. An “f-root” table makes the first note the root note upon chord change (so isn’t really a table in the usual sense). Assuming you measured the table data by recording a chromatic scale on C and then playing every chord on C, the data you got for an “f-root” rule and its standard counterpart should be identical because there’s no change of root.

There are 4 pairs of identical tables in the current conversion tables file:

• 2 (Chord basic (for chord parts)) and 28;
• 4 (Chord var 3 (for chord parts)) and 29;
• 18 and 31; and
• 19 and 32.

So it doesn’t look like the missing “f-root” table numbers are within the 0–35 range.

You have said previously that using table numbers above 35 gave “incoherent results”. I’m wondering if you missed something in those 220 tables, or maybe the “f-root” mode is specified by some other means.

File format errer ex01.ac7

Since I bought a CASIO CT-X5000 keyboard, I have been trying to write a program to convert AC7 rhythm files to mid and vice versa in Delphi, but so far to no avail.
Following all the instructions to AC7maker I created the ex01.ac7 file, but when I try to transfer the file to the keyboard using DataManagerCTX.exe, I get an error:
File format errer ex01.ac7
What can you advise me?

P.S I know the Delphi programming language and Python language a little

Allow users to specify a midi device (sysex_comms.py)

Script sysex_comms.py tries to open /dev/midi1, but my casio keyboard is /dev/midi2 on my pc. I think it should be better to allow the user to specify a midi device with an option.

Unknown event

Hi, excellent work!
I get these errors when I try ac7maker. What could it be? Thank you!
I have a CT-X3000.
