CZEdit v1.12
============
(c) S.J.Borrill 1993,1994
N.B. This application is Freeware and as such can be distributed
freely as long as no profit is made and any charges cover only postage or
media. I retain the copyright and the application must be distributed in its
entirety (including this !Help file)
This application was written to allow patches for CZ-101 or CZ-1000
synthesizers to be stored and edited easily. A MIDI interface corresponding
to the Acorn standard must be present in order for the program to run.
If you are familiar with programming a CZ the parameters shown will
be self-explanatory. If not, then read the manual as I do not have room to
go into it here! A few points however:
1. The two rows of small bars underneath each envelope represent the
END (red) and SUS (black) positions
2. If a writable icon is selected then the UP and DOWN icons in the
appropriate window will alter the parameters
3. Clicking on light yellow boxes or waveforms (e.g. Line Select)
will alter the contents
4. To load a patch from the keyboard, set the MIDI channel and
voices number as appropriate and then select GET VOICE from the menu.
5. The menu options are as follows
Info -> Look and learn
Save -> For saving your patch on disk
Send voice -> To send the voice being edited to the CZ
Get voice -> To get the selected voice from the CZ
Set name -> Selecting this will make the save filename equal to the
voice last downloaded (e.g. Internal1). This is very
useful for dumping the voices to disk as a backup without
having to think up names.
Temp Send -> When selected, any voice sent to the keyboard will
not be stored anywhere, but will only be resident in the
temporary space (i.e. can still be played and edited
but will be lost if voice changed). This can be stored as
normal using the WRITE button.
Graph ... -> Opens a window allowing the envelopes to be edited
graphically.
Quit -> Gets rid of the CZEdit (N.B. does not ask for
confirmation)
6. If TEMP SEND is not selected than any voice sent will overwrite that in
the keyboard, so be careful.
7. Any bugs, hints, questions, money or interesting patches should be sent to
the address at the end.
8. The graph window is not perfect, but is quite usable. The slope of a
segment with a rate of 0 is exaggerated so that it is easily seen.
**************** VERY IMPORTANT ****************
The protect switch on the back of the keyboard
must be set to OFF for the keyboard to receive
data. Also, the keyboard does not respond to
system exclusive data if the MIDI channel is not
set to 1. Very weird.

History:
1.00 All icons in one large window. Only one set of eight icons for both END and SUS parameters.
1.01 Decided on two banks of radio icons for END and SUS. FormEd crashed
whilst saving (too many icons I suspect), so I split it into two windows. I
got input and output files to correspond on 4/1/93
1.02 Save window disappears after saving and filename is updated. When
downloading a patch, the icons are not updated one by one as when the
envelope window is open, this is very slow.
1.03 Can now load from disk at last! Alter file format so that voice number
is saved as well
1.04 Pressing RETURN now moves the caret through the windows. Everything
seems to work as expected!
1.05 Steps after END are blanked out and the END level is unwritable.
Unfortunately this negates the speeding up of v1.02! (As Wimp_SetIconState
updates the screen)
1.06 Patches can now be downloaded permanently instead of into the
temporary workspace in the keyboard.
1.07 Various bugs corrected. If keyboard does not respond after 2 seconds
then an error is produced (previously it crashed!). Caret inserted at
correct position.
1.08 Sorted out slow screen redraw. First release
1.09 Enormous bugfix. Basically it didn't work. And now it does :)
1.10 Graphic envelope editing and general smartening up. Some 3D templates.
1.11 Can be used without a MIDI interface, i.e. checks for presence and then
greys out irrelevant menu options.
1.12 Small bug-fix. Altered templates to allow for proportional fonts in icons
(as I've just got my RiscPC).
