Why the playback stopped for 1 second several times? Is the hw buffering?

Playing on SymbOS, on the other clips it can be, as it is reading from the SD card, but reading from its USB it sounds continuous. I have tested the last video on two computers and there aren't pauses.

Maybe  you refer a pause when I click on the NEXT SONG button on the SymAmp player? It is closing the actual mp3 song and searching the next song in the SD.

Observe how the mouse pointer manages the player.

Please, try to play the videos on other equipment, for example on a phone.

Really, I don't ear those gaps. I will try to play them again to see.

Only in the very first short video I ear some crackling, but it is because I am holding the phone on my hand. On the second I used a tripod, and on the third I leave the phone on the table on a weird angle.

I am discovering new uses for this little beast of cartridge. I am finishing the translation of the minimal SEplayer from MSX Basic to Enterprise Basic. Soon I will show a new video.

It actually plays the following files: MP3, AAC, OGG, WAV, WMA, MP4(audio), and surprisingly MID(Type 0, probably with a modifiable instrument table... ). The Basic program works as a simple DOS command interpreter, you can make a sort of DIR and select the name of a file to play from the cartridge USB port. You even can change the path, enter or leave a directory on the pen-drive disk tree. All made with AT commands on an easy basic listing...

Initially the SE-ONE was designed to also have a MIDI interface, but Hans says that the MSX community showed little interest and it was dropped from the final design. It is reasonable, as there are a lot of classic commercial MIDI cartridges  for the MSX range of computers, and a lot of projects made by users. On the other side there is no popular software to manage it.

But Hans says that the UART port was left as a header for communicating with the  Arm processor, the hearth of the cartridge, so he proposes to add the MIDI interface idea on a eventual Enterprise SE-ONE cartridge. This, he says, will need a software to be programmed on the Enterprise side....

Another curious application of the cartridge is as a speech synthesizer, an emulator of the SP0256-AL2, exactly the same chip inside the Enterprise Speakeasy interface.... Allophones can be sent to the cartridge by means of an AT command.

He is now hard working on a DAB+(digital FM radio) receiver for the SE-ONE. Once finished he will send me the schematics to add the MIDI interface to the cartridge.


As you can see this concept cartridge is constantly evolving and being improved.

Hello Hans. Here I am emulating your work with your CPC AMSDAP , trying to build an interface with MSX slots for the Enterprise, but as a side effect showing the wonders of your SE-ONE cartridge, the first and only module I have tried on my prototype....

Is the first time I know that the software(SymAmp by Prodatron) is made before the necessary hardware. You launched the cartridge on summer 2017, but we have the SymbOS Enterprise port for several years now... 

Well, the secret is that SE-ONE is a clone of a MSX Sunrise mp3 cartridge from the 90s.... and Prodatron leave code inside the player to manage that old MSX I/O cartridge. But now you have added some new lovely tricks like the FM receiver.

The clever idea of the AT commands is another of your innovations, and allows all the characteristics of the module to be managed from any high level language interpreter almost from the first time it is inserted on the slot. It is demonstrated with the previous simple Basic listing.

I am still discovering new treasures....

Please Zozo or Admin, can you make a separate thread with all the SE-ONE related messages?

Hans proposes "SE-ONE music file player" for the title.
