Hey @El_Corsario,
Unfortunately, at this stage there are no further plans to introduce new features to the MCX8000, only bug fixes as and when needed.
In regards to your question on file formats, please see the following from our FAQ:
What are the supported music file types that can be played in Engine?
- WAV : 44.1kHz, 16bit/24bit Stereo
- AIFF : 44.1kHz, 16bit/24bit Stereo
- MP3 : CBR/VBR 44.1kHz, Stereo 32kbps – 320 kbps
- AAC : CBR/VBR 44.1kHz, Stereo 64kbps – 320 kbps
We do not offer support for unsupported file formats.
Regards Jay
