βασικο γιατι ειναι 6 και δεν ξερεις ποιο ειναι
#ENTERING TEST MODE & INITIAL SETTINGS
-Hold KEY TRANSPOSE, turn on your JUNO-106 and release KEY TRANSPOSE.
*The display should now show '-_'. This means that your JUNO-106 is now in
'test mode'.
-Turn on POLY 1 and POLY 2.
*Your JUNO-106 is now in 'rotary' mode. The display shows which voice is
playing.
-Do following settings:
-RANGE to '8
-PWM: man
-SQR & SAW: off
-VCA switch to ENV
-PORTAMENTO: off
-All sliders to 0 except:
-VCF FREQ: 10
-KYBD: 10
-VCA: +5
-D: 10
-S: 5
-R: 2,5
*Your JUNO-106 should now be silent
#FILTER TEST:
-Make sure SQUARE, SAW, SUB and NOISE are off.
-Set FREQ to 5.
-Set RES to 10.
-Play a few notes.
*You should hear sound from all voices.
*When playing 6 times the same note, you should hear 6 time 'almost' the same
note.
*If you hear no sound from a voice or the pitch is 'way' off, then that voice
has a broken VCF. If the pitch is a little off, then your JUNO-106 needs
adjustment.
-Now play a bit with different RES settings. The sound should disappear for all
voices at about the same RES level. If a voice still plays with a RES level far
below the ones where the other voices stop, it means that this voice's feedback
VCA is hanging.
#NOISE TEST:
-Set NOISE to 10.
-Play a few notes.
*You should hear noise (and noise only) from all voices.
*If you hear constant noise without playing a key, then you have one or more
hanging VCA's.
*If you hear no noise at all, then you have a dead noise generator. There is
only one noise generator.
*If you have one or more voices without noise, then the VCA for that voice is
dead.
-Set NOISE back to 0.
#WAVE FORM TEST:
-Turn on SQUARE.
-Play a few notes while playing with the PWM slider.
*You should hear sound from all voices and pwm should work too.
-Turn off SQUARE and turn on SAW.
-Play a few notes.
*You should hear sound from all voices.
-Turn off SAW and set SUB to 10:
-Play a few notes.
*You should hear sound from all voices.
*If any of the above failed for a voice (except the ones that already failed in
the above noise test), then that voice has a broken wave generator chip.
*If you have a hanging note, then play some different notes with any wave form.
When the pitch of the hanging note changes, then the voice you last played has
a broken VCA.
-Set SUB back to 0.
