Hey guys! :synth:
Stage 1
I got a faulty ESQ1 for repair, the main problem now is - no audio output on any DACs. To reach someone, who is skilled with Ensoniq stuff is impossible, though the boards are known to be fairly easy to repair. The unit powers on, and the display shows the starting screen and then the current patch. Buttons seem to work fine
I must say, that the unit is in a bad shape overal, so it could be anything, I did research, but it gets confusing quickly..
I ask you for advice, what should I look at firstly?
Stage 2
Ok, so I won't describe the hassle of cleaning the synth inside and
out, but concentrate on what I might have spotted for now.
Keyboard:
Perfectly, needs to be fully replaced - many keys are damaged, the
chassis has broken key levelers, fixed with nails and tape:) and what
is interesting- my metal ESQ has the keybed installed from the plastic
one. The keys do differ. The keys work fine over MIDI, so do the Pitch
and Mod wheels.
Buttons/sliders:
All buttons work, so does the data potentiometer. Can't say for the
Volume, cause there's no sound coming from outputs, as I mentioned. I
cleaned the sliders, btw.
MIDI:
The synth responds to program data, and sends MIDI just fine. I
connected it to MidiOx, so I could check the Midi trafic - all
controllers send data. I could load the patches into the synth, but
the battery is dead, as suspected, and all patches return to Brass1
when power off. I performed a factory reset. FILTER tuning showed
figure 144, what seems ok, according to the manual.
Power:
It powers fine, but at first had some hum and buzz, that are gone now.
I reseated all cable inputs where possible. The power supply is 220v,
seems to be made in Italy, so as the keyboard.
OS :
My ESQ runs OS 1,75, that is archaic really. If I repair the unit, I
will definitely install the 3,5
Will do some simple tests tomorrow, but I'm not qualified to diagnose
the Volume problem. At least I localized it, since it was not keyboard
or software error
Sequencer:
The sequncer works great, and sends a Metronome Click on output, so perhabs that is not an A/D converter problem?
Looking forward your help and advice!
