The Yamaha AN1x Synthesizer mailing list

Leeze –

 

I don’t want to discourage you but really man, considering your severe
symptoms of anomaly, you’re barking up the wrong tree with the firmware
upgrade.

 

Back when the chip was released by Yamaha, it was only the smallest number
of users who noticed any change after installing it (including myself).  The
people on this list are who I’m referring to… and they would probably be the
most vocal as well as geeky enough to explore the synth’s innards.

 

As Jon said, the 1.04 chip addressed a few minor bugs.  I searched the
archives for you and found these previous posts:

 

(From Jon 2/18/07)

It's been some time since I corresponded with Yamaha Tech Support regarding
v1.04.

I inquired:

<< it's my understanding the v1.04 OS corrects an erroneous 'low voltage'
warning which
can occur prematurely and that it also corrects the audio response when
modulating the
depth, i.e., return, of delay effects. Is this correct? >>

They replied:

"Version 1.04 does correct the symptoms you described."

So, AFAIK the MIDI Start/Stop issue you've brought forth as an issue is the
third fix
addressed by v1.04. To be honest, I'd never noticed it before you mentioned
it
:-)

pressed
down on a key. The tempo delay works without a glitching.

So the three things that OS 1.04 does is:

1.	Corrects a premature low battery voltage warning
2.	Corrects audio response when modulating effects
3.	Corrects MIDI start/stop errors in the sequencer section

 

It’s not going to fix not responding to MIDI or your screen going blank.
You need to open the back of that synth and try what I told you about
re-seating chips and connectors.  After all, IF you were ever able to obtain
the ROM chip, you will have to open up the synth and remove the old one
anyway… so instead of wishing and waiting why don’t you get inside there and
fix it now?

Well if you can give me the contact please do. I would like to try a 
new OS chip but I will also try the suggestions here in regards to the 
battery adn pushing the chip in.
