Technics SX-G100 sustain problem

[Guest]

Hi, I am new to this forum. I’m an organist and have a technics sx-g100 which I am still trying to understand fully!

I have recently started using the knee lever to change sounds, but have come across a problem in that when the knee lever is down, the sustain doesn’t work on the upper and lower manuals, for sounds 1,2 and 3 (the organ sustain still works). So the sustain buttons are highlighted and the sustain level is set at 5 for example but there is no sustain. If I fold the knee lever away, the sustain is heard again... Very strange!

Any ideas??

Thank you
Emma

I think you may find that the knee lever defaults to sustain when it's pulled down. Assigning it to change registration pistons (which is I guess what you're doing) should in theory override this, so it does seem odd.

IIRC, you can assign registration shift to one of the kick switches on the expression pedal, as happens with most makes. That might be a solution, unless you're already using both kick switches for something else, of course!

It's been a while since I read through the manual of the GA3/G100, though. Around 20 years! :)

Hi, this is strange.

Usually the knee lever should only affect the sustain if the knee lever‘s „Switch assign“ is set to „Sustain“. And it even only switches off after the lever is pulled right at least once on my GA3. The one needs to keep the lever pulled right to have the Sustain enabled.

Maybe in one of your performance sets the knee lever is programmed in that way, and you get activated it by „chance“? (I don‘t know if this even stored in each performance set however, never tried).

Thanks for your replies. On my previous organ (EN4), I always used the kick switch to change registration but on this organ, the switch is really worn and my foot slips on the volume pedal when trying to use it, hence why I started using the knee lever instead.

It’s interesting that the default action of the knee level is to add sustain... I wonder if it’s got confused when I’ve set it to registration change. I’ll have a fiddle with it and see if I can work it out!

This organ is certainly a lot more complicated than my EN4! Thanks again for responding to me, it’s nice to have found this forum as the instruction manual isn’t that detailed!

You may still be able to find a replacement kick switch, try W D Greenhill. - www.wdgreenhill.com

As for slipping off the pedal (or making sudden changes of volume!) when kicking a switch, that's down to practice, as always, but if you did so on the EN4, it should be the same here.
