LCD character mappings

[shooking]

Hi all

I know I saw this in a panel recently but for the life of me I cannot find it.

What I saw, I think, was some Roland panel that made mention of Kawai – but on reflection it might have been different forum.

PROBLEM: Kawai K1r character set is almost ascii.
How to easily discover their mapping?

I understand this will be a surjection (1:1 and onto) so inversemap(charmap(i)) = i

But how to get at this mapping?
One thing I can be sure of .. it’s midi so the char is in range [0, 127]
A patch name is 10 bytes

So I could write 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 to 1st patch name (byte val) and see what happens on the name in the K1r

Then write 10, 11, … 19
up to the 127

this gets me KawaiChar(byte(i)) mapping (provided I can find a matching ASCII or even UTF-8 for what I see).

Then for i = 0, 127 do inverseKawaiChar(KawaiChar(i)) = i end

Just hoping someone might have already generate the mapping?

Best regards
Steve

You would perhaps create a lookup table.

	_chars = {'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L',
 			'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W',
 			'X', 'Y', 'Z', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h',
 			'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's',
 			't', 'u', 'v', 'w', 'x', 'y', 'z', '0', '1', '2', '3',
 			'4', '5', '6', '7', '8', '9', ' ', '-'}

So if the sysex for patch name is 01 02 03 0A, it converts to ‘ABCDJ’ – no need for string.char() etc

Something like:

console(String(_chars[m:getData():getByte(n)])

man I beginning not to like this WordPress — I clicked on reply – turns out I hit report!! Well it looks the freaking same .. and there’s no obvious cancel.. Refreshed the page

Sure I know what I need to do .. but I am unsure of two things

K1 says valid chars are (and it even gets the order wrong in my printed manual) are

” ” ! ” # $ % & ‘ ( ) * + / (a middle horizonal line) . /
0 1 2 3 4 5 6 7 8 9 0
: ; < = > ? @
A .. Z
[ a yen character ]
^ _ ` a .. z { | } -> and <- (which are wrong way around) so that's not 127 chars. I can hack my program to generate the 0 .. 127 and "observe" the output so this get me British Ascii -> Kawai Japanese/US chars
and should be reversable.

I am so sure I found some panel or some Novation mapping for a Korg or Roland that was supposed to be the same.

Your “kill the modal” trick is very powerful.

Labels can display # but I not reliably got combo to do or LCD I guess because some of these chars are used to represent a delimiter

Time for a BBQ and much beer in locked down UK .. I do hope as many people round the world that can stay healthy and have fun are able to do so.

Oh and time for some bass playing on my Steinberger copy while I flip burgers …

I don’t understand what you are trying to do.

Are you parsing user input to ensure a correct set of characters?

Or are you trying to convert to (extended) ASCII which you obviously know how to do do well?

I understand this will be a surjection (1:1 and onto) so inversemap(charmap(i)) = i
…

What does all this mean?
