MODEL: AX60 No. MS-0008 DATE: March 1986
001 Subject: To improve performance
The ROM IC program has been changed to improve the following points.
1. AUTO TUNE request by MIDI is recognized but is not transmitted.
2. AUTO MUTE request by AUTO MUTE button is accepted up to 6 times causing
other functions inoperative for up to 30 - 35 seconds.
3. When VERIFY is executed and the data recorded on the tape and that of
AX60 is different whatever the reason may be, the data in AX60 may be
re-writen when PROTECT switch is off.
4. Since the position of PITCH BEND setting VR is memorized when the unit
is turned off, when the unit is turned on again after changing the
posistion of setting VR, the amount of Pitch Bend effect is different
from its VR position.
5. In SPLIT mode, the MIDI channels are set for Upper keys and Lower Keys
separately. But even after SPLIT mode is released, MIDI channels are
not caceled thus AX60 accepts 2 MIDI channels.
