Waveshapes are not really editable except for the shaping envelope and the amount applied to the sample. Just a few oscillator parameters can be edited including: volume, tuning, panning and delay startwave.
I had to repair some of the circuit traces.Back panel terminal connectors: - main out - aux out - Midi interface - 2 assignable pedalswitche inputs Front panel terminal connectors: - headphones out - 2 card slots for data and PCM.Ī basic patch is composed 1 or 2 samples oscillators that can be set in 2 manners: 1- single: 1 oscillator per sound 2- double: 2 oscillators per sound.
So I followed your advice and replaced all the dead caps. Found one good motherboard and it lasted for a good while. Hi Hajo and readers of this topics, is there also a site like this for the Korg M3 somwhere? This for the M1 is excellent!!!!!!! Thanks to Hajo.
Once I do that, how do I reset to the to factory setting? Any other ideas as well? See this comment on how to pre- load the factory sounds. I have only the default Piano sound on my Korg I have been advised to change the battery. Be careful and do not touch the power switch unless you know what you are doing. I am not sure if you will be able to get it back on track as a keyboard, rather as a sound module. I have a 01w that need a tune up the power switch is disconnected and the various keys dont sound or lay flat thank you hope you can get me back on track denver nick.
What can the problem be? Is the battery ok and did you try a factory reset? If the answer is yes and the behaviour still as you describe, then your 01W needs professional servicing. I can change the sounds if I go into Edit Program and manually select, but once I select Combi or Program it reverts back to the original sound. It seems to be stuck in a piano song, doesnt matter if I switch to Combi or Program, Banks or anything. I loss many sounds i need for recording with the same sounds, for re-make many songs and dont have idea for repair this. Many sounds, is OK, but if I apply any wave shape, the sound is very bad, have a very amount of distortion, if work in single or double osc mode, with any, WS1 or WS2the sound is broken. Hajo, where would these fused resistors be? Both comments and pings are currently closed. You can follow any responses to this entry through the RSS 2. Of course, it is not state of the art to replace an SOT89 SMD component with a TO92 through-hole component, but firstly it would have taken some amount of effort to get the SOT89 variant and secondly it is yet a robust and well-functioning replacement in this case fitting pinout and leads, no thermal or mechanical aspects to be considered. As you can see on the photos I also replaced IC53, which stabilised at 4. So I replaced C and patched the broken trace by scraping off a bit of solder resist and bridging it with solder. And the cleaning should be repeated a few times with fresh swabs. To clean this type of mess I prefer cotton swabs heavily soaked with isopropanol isopropyl alcohol. The caps C95 and C96 had ruptured and the sub-PSU and even more distant parts were spattered with electrolyt.Īnd the really bad thing about leaked electrolyt on a printed circuit board is that it causes corrosion and damage of metallic parts and circuit traces. But then, on the next day, all analog outputs were dead.
After a short power off it recovered without further action.
