A few Akai AX60 questions.

Postby abend » Wed Mar 09, 2011 11:29 am

just a two quick questions.

1.) keys from the Poly-61 will fit on the AX60, correct?
2.) I've seen someone selling an eprom software upgrade for the AX60. what is this?

I believe the keybed is the same as a poly61; the AX-60 keybed parts I've seen online were identical to the the ones out of my buddy's Poly61.


I can't comment on the EProm

I'm curious so I sent an ebay seller of the EPROM upgrade a message inquiring what the purpose is.

looks like its a few minor OS bug fixes

The following are changes/bug fix's made to version 1.2 from version 1.1, I don't have any info for version 1.1 from 1.0

MODEL: AX60 No. MS-0008 DATE: March 1986
001 Subject: To improve performance
0.
~he 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 un~t
is turned off, as 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.
Ref. No. Part No. Description
(NEW) 3-IC7Z EI-364674-B IC TMM2764ADC AX60 Vl.2
Changed from January 1986
Service Ref. No. : CNLOlOl, CNL0113

I just got off the phone with VST... they don't have any info on the v1.0 - 1.1 update. Anybody here know how to get this info. I'm wondering if dropping the $55 on this Eprom is worth it.

I have a v1.0. I wonder what other folks have here. Maybe we can compare bugs.

I've got a few AX60s, let me check what ROM they have. If I've got 1.2 I can provide the chip for $30...
