Juno-6 Help

Post by Hossinfeffa » Sun Apr 27, 2008 4:13 pm

The other day my Juno-6 did something strange, and was curious if anyone had any idea what caused it.

I was playing it like normal, with a thick bass type pad and it was working fine. But when I pressed the lowest note (C2) all I got was a type of high frequency white noise sound. Someone in the room with me thought it was that the key contacts needed to be cleaned, but if it was that, then you would still hear the original sound, just it would be playing on and off. I went away for a few minutes, came back and played the note and it was back to sounding normal. But now a different note doesn't play at all (most likely this is a key contact issue since it was flickering before and now it just stopped completely.)

I plan on taking my Juno into a shop soon for a bit of servicing, but how much can techs usually accomplish in an hour? The nearest tech is about an hour away driving and costs $80 an hour. What I'm mainly looking to get done is just clean the key contacts and clean the sliders/repair slightly bent ones.
Well fffff.

you need to differentiate between key and note. for the sake of expediency, lets call:

key=low C. the physical piece of plastic if you will.

note=a pitch. as in, your juno can play 6 notes at a time. better known as voice.

if it always happens on a particular KEY, thats a key contact issue.

it it happens on a NOTE, as in somewhere in your 6 note rotation, thats NOT a key contact issue.

considering junos are known for the faulty voice issue, my money is on a bad VOICE. i would GUESS you were hearing a voice chip go bad. tell us more.

It's a particular key, so I guess it is a contact issue. I tried going through each key to see if it was a voice going, and it was only the two keys.

I've really only heard about the voice issue with the Juno-106, the Juno-6/60 have different circuitry and are more reliable.

It's just usually I expect a key contact issue to be either a flickering key, or not playing at all.
Well fffff.
