Hello, all;
I have a KT-88 purchased in 1995 that was until quite recently still working perfectly, both the internal synth and all the MIDI in-out-thru stuff. The only issue it has ever had was the battery warning in 2014; I had the battery replaced while living in Austin TX at Switched On for $100 parts and labor (pretty reasonable I thought).
It sat for a couple of months recently without being turned on while I replaced and reconfigured the two desktop computers (one Windows, one Linux) that comprise my home studio along with five other old hardware synths, and when I turned it on a couple of days ago, it produced (when keys are pressed) a very low volume sound somewhere in between one of the string and one of the brass presets. (FWIW, having the volume slider at full high or full low makes no difference in this very low volume sound.) I tried the reset and everything seemed to be back to normal, except for a weird fast “echo” effect on the default patch (“E-Prime Grand” or whatever it is called) and every other patch I tried. At the time, I thought it might be something that I needed to look at in the MIDI setup, that one of the other synths was on and there was some kind of weird MIDI artifact happening. I was pressed for time so I played for a few minutes to satisfy myself that the KT was okay, then powered it off.
Yesterday, I powered it up again to troubleshoot the “echo” and it was making the same very low volume stringy/brassy sound again. This time, multiple resets didn’t solve the problem, but powering it off and back on several time resulted in my getting a piano sound again, but once more with the “echo,” although I made sure that the echo was just happening with the KT by unplugging the cable from its MIDI Out.
Is this information that might help anyone guess what might need repair in the KT? Has anyone experienced something similar with a KT in the past? If it will help anyone take a guess, I’ll try to get a recording of the “echo” for people to listen to.
Thank you!
