rolandfan, you say your CD Writer doesn't recognize Midi so I am assuming your just trying to copy midi songs you made on your Keyboard to a CDR-CDRW disk by way of a Computer and the Samsung. You have to make sure if you are using a CD-"RW" disk that you format the disk so you can read and write to it. Same goes for a CDR if you are trying to copy the Midi's to the Samsung by way of Windows Explorer/My Computer. If you are trying to copy them within an External Program, eg., Easy CD Creator, Nero Burning ROM, etc. it should be a fairly simple process. I am not familiar with the Samsung 252b but if you just bought it yesterday it sounds like it's a new product vs. old product (technology wise). If it is a newly released product I don't understand why it's not reading 'recognizing' the .Mid files.

Give us a little more idea of what's going on, ie., "explain yourself better if you can".

A more thorough solution is to record your Midi's by way of your Main Outputs from the Keyboard= (Playing the Midi file on the Keyboard then running the signal into your Computer either by routing the signal to a Mixer first then outputting the Mixer Signal to the Computer.) Inputing the signal into your "Sound Card" from the Mixer or just from the Main/Aux Outs of your Keyboard, eg., to a Sound Blaster Audigy, Delta 44/66PCI, Layla Card, etc. "whatever sound card that you have that allows you to do this." Then recording that signal with a Multi-Tracking Software Recording program such as Pro Tools, Sound Forge, Cool Edit Pro, N-Track Studio, etc. The Midi file will be recorded as a .Wav file by the Recording Software. After that is accomplished then you would convert the .Wav file into the .MP3 format with a Ripper/Converter sofware program, eg., Lame Encoder, dBpowerAMP, FreeRip MP3 Version 1.21, etc. After you convert it to .MP3 you could then transfer it to your CDR-/RW disk.

Hope this helps.

Best regards,
Mike
