공지사항

Dear customers and friends,

I'm glad to announce this good for all of SD Music card buyers.
New firmware for SD Music (plus) card was finished.

 

https://youtu.be/TmVWjNK-isw


What was changed?

1) New firmware support much better for Mockingboard emulation. now it supports all channels envelope 

I spent many days and nights to make a good mockingbird emulation.

*Chorus channels are removed and it assigned to more noise channels. now it has 3 noise channels.

 

2) User firmware update support
The previous version doesn't have this capability but from now it supports end-user updates. hence end-user could update when new firmware announce.

3) VGMPlayer support

But unfortunately, I need your card, hence SD Music card owner needs to ship it for firmware updates.
After that, End-user firmware updates are activated.
Please email me (quick09 (a) gmail . com)

 

But,  worldwide covid19 is a big issue hence,  you may not easy to ship it to me and also my side having difficulty returning it to you.  please wait for good days for us.


if you have any concerns, please let me know.
Thanks
Ian Kim

VGM Player V1.21

◆ SD Music card / 2020. 4. 26. 20:55

Hi friends and customers,

 

VGM Player for APPLE II, It is version 1.21 now.

In this version, It supports sub-directory and easy file list moving with Page UP/Down.

Also for more fun, I added a Jukebox function. it is simple to play all of the music files in the present directory.

Please watch this.

SD Music Deluxe card planned a month later and this program will be announced when the Music deluxe card launched.

 

Thank you very much.

Hi customers and friends,

 

I'm glad to notice that I've made a VGM Player for SD MUSIC card.

Here is the sample play on SD Music card.

https://youtu.be/s-QGBZC4Sbo

Recorded songs are mostly Korean songs.

All VGM files extracted(Not by me) from Family Karaoke on Famicom system.

 

This VGM player used a bare control mode on SD Music card on new firmware V2.0.

It has 32KB file limit so need to manual load for next data hence, I'm considering using AUX memory or file reading way(It may have a delay while file reading).

Anyway, we have another program to play music on SD Music card.

 

Thanks a lot

Ian Kim

Dear customers and friends,

 

I'm glad to announce for new firmware upgraded to Version 2.0.

In this version, I've applied all of Envelope functions and now it works very nice.

And on the Instruments Key On timing was improved a lot so, it could play much better.

Please have time to listen to it.

 

 

This song recorded from (Not so) Cheap Tunes I

and all instruments are default(Reed instruments).

(Recording was good so some parts had a clipping, it is not sound card issue but my PC )

https://youtu.be/4IKtQfxtfcg

Here is another song from Ultima IV

All instrument selected (Keyboard type Instruments)

(Recording was good so some parts had a clipping it is not sound card issue but my PC)

 

https://youtu.be/Rz3MPOaVjJg

 

I'm doing to make a user firmware updates utility and Instrument changing utility on APPLE ][.

After finishing it, I will announce it.

 

Thanks for your waiting and Keep good your health.

Regards;

Ian Kim

Dear Customers,


I doing for upgrade firmware of SD MUSIC card.

In this time, I learned a lot more about AY3-910 hence,

It would a good time to apply it to my previous SD Music card.


I can promise that New firmware could have below functions.

1) Support Envelope but still limited on the noise channel 
As you may know, AY3-8910 have 3 noise channel and our Mockingboard have two sets of AY3-8910
Hence, the total Noise channel required already 6.
But, YM2413 chip has 9 music channels but, it doesn't have noise effect itself.
To generate Noise on Music card, I used the 9th channel and assigned it to Noise Instrument.
So, it has only one noise channel hence if the program used a noise channel with an envelope, it would influence another Noise channel too so it would have a different sound.

2)  More noise channels,  As above YM2413 having a lack of channel to emulate AY3 8910 hence, I will assign three channels for noise. In fact, needs 6 channels. but, I will try my best to express noise channels

3) Due to only available 6 channels for voices, it will be assigned all for Mockingboard channels, Hence 3 Chorus channel should be removed so the sound would be different on Music compare to the previous firmware.

4) User firmware updates, After this function prepared, Users can update to the new firmware.

5) User support functions would be added to control YM2413.
Previous version bare mode doesn't work properly. I will make a new way to control Ym2413.

So It would be much better to play music and game effects.

And If a user board needs to add a noise filter, I will do it free of charge.

I need your card in my hand to update new firmware and for the filters.
Sorry for this.

I will notify you when I ready for this.

Thanks for your waiting.
Ian Kim
