Hello here! My Kurzweil PC3K8 (service manual: https://www.synthxl.com/wp-content/uploads/2020/05/Kurzweil-PC-3-x-service-manual.pdf ) won't boot. After switch on I see following: * There is a SOUND ROM in BANK1 on Engine Board. BANK0 is empty. The same symptoms are there is both BANKs ara empty. - ...

UPDATE:
Problem solved!
The thing is that my keybed was not attached. I fight the red glue problem in parallel. With keybed attached the JV80 reacts normaly to PitchBend and Modulation. ))

Me again! ;) It seems that also TRANSPOSE switch is not working (it light up, but there is no effect). Well, I can change the Transpose Value in the TUNE & FUNCTION menu, but pressing TRANSPOSE button takes no effect then... So it is still a lack of internal connection from the controllers: Pitch Be...

Hi here! I reactivated my Roland JV-80 after a long break and the PitchBend/ModWeel and C1 are not working localy. External MIDI gear can control Pitch Bend and Modulation inside JV-80. In test Mode pitch Bend and Mod Weel and C1 Fader reacts properly according to Service Manual. I can also see C1 v...

Hola here!
At least the battery replacement can be done quick and dirty from the top...

Hola there!
Well... after some circumstanses appeared, I sold all of the TS-12. Sh*t happens. But now I own an TS12 again and have three empty desktop cases. Maybe, maybe...

Hola here!
Just wanted to inform you here:)

Hola here! I have Yamaha YC 25D Organ, but in BASS MODE (at inverted keys) the second C dont work. Its sound like the key pressed bevore (from above AND from the bottom). What can cause this? I tryed to trace the On-Off switch to the corresponding board. The switsch itself seems to work, because it ...

Hello there! Thanks for a lot of information here! My VFX-SD is alive but the VFD display is dead because of leakage . The Vbb is there, a ll the chips around also get the Vbb. The 9VAC is here. The VFD is warm. It is possible to vacuum the VFD again? At least theoreticaly? Or after leakage somethin...

Nice inspiration:

Hey, there! Just want to report a small progress I've made. I cut the side panels for the tabletop from the original ones of TS12 with a little help of a side cutter. The new panels do not cover the sides completely, like the original ones too. I think to put some wooden panels on the momentary ones...

I got the surface cutted. Just had to find someone with pro tools. Because initially I tried cut the whole surface of TS (front panel made of complex age, flat aluminium plate and second complex age at once) the Ensoniq logo was cutted too... ;( The other two I cutet the way Ensoniq logo survived......

Some additional thoughts so far: - Realised that power supply inside TS uses the whole aluminium body of the synths as a passive cooling. So I need some kind of additional cooling inside the rack case. Simple screwing the small cooler of the PCB to the rack case wall could be not enough... ;( - Cut...

It is possible to put four Ensoniqs and one CD-Rom on one bus? Otherwise I have just one SCSI interface for my four Ensoniqs. So it would be cool to boot each one with the same interface one after another... so the switch is between synths and the one interface+cd-rom...

To share the tabletop unit was also my first idea. I realized that TS12 can also boot without the display board. So I first tought, it would work with a simple "mechanical" switch... But I'm afraid that the "additional circuity"have to be. :) Never tought about sharing drives! Interesting idea! May ...
