Does YEM reference keyboard built-in samples

(1/3) > >>

hechuan:
YEM can reference the built-in samples of Genos keyboards, can we reference the SX series keyboards, or can we not use YEM to reference the built-in samples of SX series keyboards.
I would like to know what sample format is used when creating packages using YEM, wav 44100 16bit? Do you know about Yamaha's WXC audio data format.

DerekA:
Only tyros 5 and both genos have the option to use yem with the built in samples. And even then, not all of the samples are available to use

BogdanH:
YEM accepts 44100Hz 16bit wav samples for stereo (22050Hz 16bit for mono).
I have never heard about WXC audio data format. I think I've seen somewhere WXC chip being mentioned, but it was not in audio format context.

Correction: Replaced kHz with Hz

I saw this information from the official package of Yamaha. It seems that Yamaha's package has compressed the samples, but I am not very sure how they are compressed。

BogdanH:
hello hechuan,
It's hard to say what WXC means in this case. For example, if we import wav samples into YEM, then sample header will contain:
<WaveType>LINEAR16</waveType>

Of course we can speculate that WXC means something like "WaveXCompressed". But if codec is not available (or at least file structure specification), then it will remain only a guess.
On the other hand, it can also be some special wav format, similar to rex (which is actually wav, but customized for handling looped samples).
