I have boss micro br hooked up to my computer it has windows vista.I'm not finding a micro br icon to click on to open files or drag to another file to open so as to send in email.

Why you have to convert to mp3 ?. Did not the card can be removed and installed on the computer and then copied?
Where you convert the file? BR or computer?
What software you use to convert?

did you find a way? i am trying to open songs on my mac

Chances are you need a driver in your PC compatible with Vista. There are MANY compatibility problems with Vista and special devices such as the Micro Br.

Page 2 of the Turbostart manual explains that in some versions of Windows the Micro BR may appear as a removable storage device titled "Removable disk (?:)." The manual is here:http://cms.rolandus.com/assets/media/pdf/MICROBRts.pdf It also mentions free downloadable wave converter software. Hope this helps.

You can use it, but realize that you do all the work on the Micro BR and just download the result to the PC as an MP3 file. The PC treats the device just like a memory stick

Here is a link for a good freeware program that will help you:http://www.filehippo.com/download_dbpoweramp_music_converter/ Let me know if this helps.

Go to bossbr.net - Plenty of answers there! And yes, you have to master or export the tracks to .mp3 or .wav. These files will be located in the mp3 folder. Boss also makes a free .wav converter located on their website.

I would expect the formatting MUST be done by the unit itself, not formatting on a PC and then installing in this unit.

The autoplay window should have popped up, and then select "Open folder to view files". If not, open file explorer and there should be a drive labled "Boss_BR". The only playable files will be located in the MP3 folder. You have to export your tracks (Using the MBR) as .mp3 or .wav for them to be playable.

Remove card, reincert card and initialize again. card may also be fragmented, use card optimizer in menu.
