Hi friends. Just to say that the accordion in GPO4 is very handy.
If you want hear it, i made a super-quick test real playing test:
Im not kidding ... Just load the ensemble called "02 Woodwind Section One.aria" or "03 Woodwind Section Two.aria", map all the channels to "OM" and you will get this sound... in the mp3 the first part is the woodwind One, and the repetition is the woodwind two. You can replace the "KS" instruments, to avoid the keyswitching when playing chords...
Would be nice if to experiment with this, adding some instruments and tweaking the balance of volume between them. Let me know any trick you can suggest to enhance this.
