Hello. sorry to burge in…
I have a ESQ1 on my hands. cheap buy as usual. I have several issues.
First let me tell what i have resolved.
- It had low battery, replaced that all good.
- It had a faulty ribbon cable for the keyboard. and made the controller chip a bit hot. The ribbon was backwards and 2 wires interrupted. It works great now velocity and all.
All values are within range. the power supply all in range. the output opamp 084 +/-12v the -5v regulator on board ok. MJE-182 ok. 7 v out. but all filer values are 0 in filter calibration. will check again tonight power on all filters
2. The filter calibration results are all 0. all 4 envelopes work fine. (audio output is low)
