Re: cracked main board JUNO 60

I have a tech, can this be soldered? its a clean break. It can be fixed. Just get a patient tech. In my opinion (and from what I can see), it's not that bad. It probably wouldn't take that long to do. Bond the board, jump 22-23 fairly large traces... either run wires point to point (some are obviou...

Re: Ensoniq VFX-SD stuck in display self-test mode

Okay, so the DUART was sucking the Vres down and after replacing it things are looking good now - but I'm stuck with the infamous Keyboard Calibration Error. I checked the keyboard connections, and someone had hardwired the connectors together already, but they used real thin of wire and they looke...

Re: Ensoniq VFX-SD stuck in display self-test mode

All the PSU voltages are within spec except Vres going to the mainboard which is 2.48VDC. I think George already gave you a lot of good technical advice. In other words, disconnect the PSU from any other boards so that the reset line cannot be dragged down by a fault from any other boards (display,...

Re: Ensoniq ASR-X Sequencing Question

like i said, split the loops up... Your answer was vague and non-committal, in my eyes, so I was giving a firmer explanation as to (what I'm assuming to be) the process. "Split the loops up" could mean that they used each 909, Trident, Rhodes, and SP1200 section independently and then layered them....

Re: Ensoniq ASR-X Sequencing Question

I interpreted that as the ASR10 was being used to record major segments (from a mixer 2-bus) such as verse, chorus, etc. and then they just played the verse section 4x, chorus 8x, or whatever for the entire arrangement. Similar to the concept of flying in the choruses on a DAW.

if I press the parameter group up button Im getting "card not ready" on the display !
Hold down the two bottom-right keys and then power on the D110. This should put you into test mode.

- Go through switch test at the very least.

Let's make sure there's nothing strange going on with the unit.

This only happens with B and C keys on the lower octaves
Fairly random guess? Bad diodes in the key matrix in that specific section which ordinarily would prevent "ghosting".

These discs are hard to find and they shouldn't be! I especially object to people making money out of these.
Highly agree.

Valiant attempt, sir! But I believe you copy/pasted a truncated link :(

The display isn't working, none of the LEDs light up and there is no sound on the output.
Check all the basics such as seeing that the CPU is getting 5V, clock, and reset.

That said... cross your fingers and hold down the STORE button while powering up. If you works again, you're blessed.

The saved patches stay in storage as long as the power adapter is plugged in (whether unit is on or off). Not much useful if the keyboard has to be moved around and I'd definately preffer if they resided permanently.
They just have to be battery backed, that's all.

Re: Yamaha PSS-480/580/680 firmware?

Replacing the Rom sounds would indeed make more sense. Are the 100 preset patches written in from sysex files? You would have to use an EPROM programmer to burn a new ROM and then open up the synth to replace the presets. And you'd also have to wire up a bank selector knob, etc. if you wanted to ex...

Re: Yamaha PSS-480/580/680 firmware?

Increasing the number of save slots is more what I had in mind than replacing the onboard sounds. Keep in mind that I haven't deeply explored this idea, but: I think increasing the amount of user patch slots is more or less "impossible" because (at least on the PSS-480/580) they are kept in 64K of ...

Re: Yamaha PSS-480/580/680 firmware?

Does anyone know if a firmware revision or update was ever released for these Yamaha keyboards? I'm wondering if there's a way to permanently replace the rom presets with custom ones. I think there are two separate questions there. If Yamaha ever released some "final update" for that series, it wou...
