Hi there,

What format is the material in? I quickly looked up the specs, and, from what I can gather, we're talking about a stand-alone, multi-track digital recorder. So, we must be talking about audio files, and each track you have recorded on the device will presumably result in (at least) one audio file, making up the total number of stems of your project. In order to import those into Music Maker, they would obviously need to be in (or be converted to) an audio file format supported by Music Maker (e.g. WAV). You would need to bring over the audio files from the device's storage to your computer's hard drive. Check the device's documentation on how to do that. Then import each stem from the "File manager" tab of Music Maker (or from Windows file browser) into a separate track of your Music Maker arranger. Now you can do additional editing, mixing and mastering in the software.

Good luck!
