Re: Your latest musical purchase

Just received a Korg nanoKontrol2 MIDI control surface as a birthday gift from my wife and son, along with a powered USB hub and mic stand clip. I'm planning to use it as a physical controller for some of my iPad apps, most notably Galileo Organ.

Re: Ensoniq SD1 issue

Just as a heads-up, unless you sourced the 68HC11A1P directly from another Ensoniq (such as a chip pull from Syntaur, etc.) then you'll likely have a completely non-working keyboard when you swap out the chip. The 68HC11 has 512 bytes of on-chip EEPROM which can (and, in this case, needs to) be pro...

Re: Ensoniq SD1 issue

Nah, not on the KPC board but the actual induction PCBs. In the upper-left of your last photo there are three groups of two resistors. In the center pair of resistors there's a transistor. It looks distinctively more brown than the solid black transistors everywhere else -- almost a deep rust. Coul...

Re: Ensoniq SD1 issue

Ah, now I see it. On my close-up of the ribbon cable it's quite obvious. I'll open it up and look again, that does look damaged in the photo.....

Re: Ensoniq SD1 issue

I don't know if this is the problem, but Q31 on the keyboard looks like it might be cooked. I don't know if that's the lighting or not, but it's a possibility. Is that what's circled here in black? I'll open it up and check that again.....might be the lighting but I may have missed it. Thanks for t...

Look carefully at my second and third photos. There's a ribbon cable soldered to points on each of the coil boards. No issues there.

Re: Ensoniq SD1 issue

Sigh. I reassembled the keyboard and put it back into the SD1. No change, the original problem still exists. At least I didn't screw anything else up and the keys and coil boards are clean again....

Re: Ensoniq SD1 issue

OK, I finally had the opportunity this afternoon to set up a table and take the SD1's keybed out for a look. Following instructions I found in several online sources it was relatively simple to extract the keybed and remove keys. Let's see what I found. Here's the top of the coil boards under the ke...

That's going to be my first task in the repair process as soon as I can clear a good chunk of a day to work on it.

Ensoniq SD1 issue

Good evening, VSE! I'm having a problem with my trusty Ensoniq SD1. When I play individual sounds in sound mode, they play with aftertouch or pressure (in Ensoniq-speak) full on. The effect is most commonly volume, vibrato or filtering. Here's where things get weird. If I press the footswitch down (...
