I was able to record intro for a minor scale tune. Set parameter to C m, then record the tune play in Cm. Style Creator plays this tune correctly, very similar to recording a C major tune by set parameter to C Maj.
With either C Maj or C m recording, the parameter of the RYTHM2 has to be set to C Maj or C m, with the default C M7 setting, the recorded tune (major or minor) will not sound correct within Style Creator and during actual style play.
These are discovered by trial and error.
Style Creator has many quirks, not very user friendly and these slow down style creation process and introduce annoying issues. Here they are:
1) most tune are in major or minor scale, for some reason, the parameter for all instruments are set to C M7. User has to change the setting for EACH channel. It would make sense for the settings to be C Maj (or C m) for all (except RYTHM1 and RYTHM2). If any channel (11-16) uses a percussion instrument, user would change it to C M7.
2) root transpose: by default all channel have fixed root, default should be set to root transpose for all except RYTHM1 and RYTHM2
3) EXTREMELY ANNOYING ISSUE: once a channel has been recorded and later, reselected for RECORD, the setting goes back to C M7 !!! Even if one only reselect it to increase VELOCITY or to QUANTIZE.
4) channel volume: (confusing to me), if I change the volume of a channel (of my recorded intro), this volume setting also applies to ALL 4 main variations.
I will try Style Creator on Genos and see if it get improved to be more user friendly.
During my career, I have never seen a product design in Japan to be user friendly. One typical example that I have encountered. The product use letter 'A' to create a file, 'B' to copy a file, 'C' to delete a file.
