Oh.. it's a difficult bug, because it not always appear. Most of time, it appear after 1 hour of work.

It appear only with the drum kit which use ram samples and if the arranger is playing when I change the pattern to one from the HD.
exp: i play one pattern, (from the ROM, flash RAM or HD) when is playing, I want to chain another pattern, I press the single ram style button, and i press one of style button to change the page of the screen. Then, when I press the button, the pattern wait a little (100 msec), as a computer too slow, who read a music.
but perhaps, when I change to another style (who use the sampled kit from ram) when the arranger play, the synth sing : LIJHFSJHSJLFGHSLGHSL!!!!!!!AAAAAAAAAAAIIIIIIIIIIIIIIIIIII!!!

If you want, I send to you my oriental kit.
i know to send you all (wav files, msp files, ins files, pat files) but, where the kit mapping is saved?
and what is your email AJ?
