Correct Fran!
The missing feature always request are only the CDG Mp3 on multiple display and then update the Preformance system that burn as Presets the whole MS pannel.
After this last two features, I think that the MS have the all tools that you need.

About the arranger:
Now on MS are available 2 arranger engines:
1) livestyler: integrated on MS OS and full controlled the arranger section.
IF there need some updates and features, just stress Norber and NOT Lionstracs, this because we use the native binary windows version and we can NOT edit/update NOTHING.
IF you don't like the YXG-50 VST, just open the midi I/O and remap the Livestyler to another sounds device or just load another VST, where is the problem?

2) Qranger: is already full integrated API on MS side pannel, we don't have to develope nothing more.
Qranger is based on Qtractor engine: http://qtractor.sourceforge.net/qtractor-index.html
Qtractor is still in progress developement and now is also full controlled by the Bheringer BCF2000.
When Rui Capella update the Qtractor, automatically is updated the qranger too and a new package will be released.

I will spend my time now for complete the 3 new totally GIGA products....
In october you will see some nice....
