Coding Error When Using EzCode4F to Add Voice Files
Use related sound editing software to add voice files and then compile MDB files used in EZCode4F instead of directly adding voice files

1
Sound frequency error may occur during voice or midi play
If you use PWM as the voice output mode, and use mode2/mode4/mode6 for voice or midi play, try the following method to avoid the above problem
2
When you use unequal judgment sentence (! =) for bit condition to jump to the specific path, the program-executed result is not identical with the judged result by formula
If you need to use judgment sentence for bit condition in your project, you can modify this sentence into equal judgment sentence
3
A low-pulse output of SYNC pin when power on.
If you use PWM function in your project, you can set the Low level (initialized) for it in IO PIN page

1
The Application of Portamento
In order to prevent making this error, users only need to set the timbre of the corresponding portamento codes as “instruments” if they want to make portamento effect with over 4 halftone notes. By this way, the portamentos of those halftone notes can still be played normally.
2
Ineffective Key Press With Alone Key
 If your project must use the PraOutFirst option, try to set a non-empty (no “X”) path for all pins. If this still cannot solve the problem, please contact Alpha for support.
3
The program size exceeds 64k
The reason why this occasion occurs is the adjustment of codes when your compiled program size exceeds 64k. It will result in the command codes occupy more space by around 0k~64k. Then you will find that the size of program increase much than expectation after compiling.
4
Pitch error with the timbre edited
Do not use the above files in PatchWaveEditor4F v2.10 and use *.wav file instead, or in PatchWaveEditor4F v2.00, use a *.wav file to generate pw2. As such, the correct TDB file can be produced.
5
Make a timbre under Mode H or H+R or H+S+R and the waveform length of the head exceeds 2 seconds.
Try to limit the length of the head waveform within 2 seconds during timbre making.
6
In EzCode4F2.00 and EzCode4F2.10, the parameter Pitch can cause compiling error and hence an incorrect result.
We recommend that when use ShiftKPH in EzCode4F2.00 or EzCode4F2.10, always set Pitch to 0.
7
When you use unequal judgment sentence (! =) for bit condition to jump to the specific path, the program-executed result is not identical with the judged result by formula
If you need to use judgment sentence for bit condition in your project, you can modify this sentence into equal judgment sentence
8
A low-pulse output of SYNC pin when power on.
If you use PWM function in your project, you can set the Low level (initialized) for it in IO PIN page
