Question about Korg Legacy Collection

7 Answers

Intermittent problem with an electric piano.

While playing instrument, sound will either suddenly seise or the last note played will sustain and reverberate indefinately even when key is released. turning keyboard off then on again resets most of the time, other times keys produce no sound. Intermittent= one second to hours between glitch. Note of interest; instrument performs flawlessley while controlling other synths thru midi. any ideas?

    this problem has nothing to do with the legacy, this unit is apprx 20 years old, it is played through an amplifier, not a computer.

    sounds probable except the fact it plays perfect while controlling an e-mu proteus 2000. keys work fine.

It sounds like a keybord failure. The keys of the keyboard can wear out over time. This might result in keys that don't make good contact (you have no sound) or that remain in contact (last note played will sustain ) even when pressure is removed. Probably there is no easy solution for that. I may suggest to disassemble the unit and clean the contact surface under the keys and keys itself with degreaser (40 % ethyl alcohol or 70 % rubbing alcohol) and let it dry for couple hours or dry it with hair dryer. In most cases it helps. If no help you need to replace the unit
Good Luck

Hi and welcome to FixYa,

Offhand, I would suspect the effects processor rather than the keyboard itself.

If you are considering a DIY (do-it-yourself), the unit must be opened to access the effects processor board. It is also required to have familiarity with electronic components (digital & analog) and circuitry, use of a DVM, logic probe and even a soldering iron. Access to a service manual would be to your added advantage or at the very least a schematic diagram. Of particular interest to your diagnosis would be the phase shifter and the effects generator/processor.

Should you be uncomfortable performing a DIY, then perhaps your best bet would be to seek the services of a qualified professional.

Good luck and thank you for using FixYa.

    The service manual would provide you with the block diagram, the signal flow, where the PCBs are located, test modes, function test, how the MIDI is implemented and therefore why the MIDI is good but analog audio has intermittent issues. Service manual maybe purchased from here and/or here.

Yes this is because you are not connecting it to a computer that has a USB 2.0 port, you are using a USB 1.

USB 2.0 is a much faster connection just like firewire.

so your only option is to use another computer, a new up to date one.

hope this helps

Gets whacky and freezes up every 2-3 minutes


Is this the correct sustain pedal for this unit? It sounds like it should be a momentary button type. I would look into that. Some have a push to work type of switch and some use momentary. If it is, I would open that pedal and clean the switch with contact cleaner, as it appears to be sticking.

My casio privia px830 pedal doesn't sustain enough,


It could be that the electronics of the pedal are dirty, or that dirt has collected under it causing it to not depress all the way. Try taking it apart and cleaning it with a Q-tip and rubbing alcohol. Be very careful of any wires or delicate articles.

I would check your fingering... You MAY be late in hitting a particular note and the using auto chord... this can cause the problem. Another thing is if notes are hit with different velocity that can affect the sound. Sometimes certain voices have VELOCITY switching which actually changes the voice depending on the velocity you hit a note.

My P85 digital piano have not a good trasmission with midi cable USB, in particular when press the sustain pedal trasmit a note to pc. Thanks


It is IMPORTANT to realize that the SUSTAIN is NOT attached to a note, but is an independent MIDI message. Hence it is up to the external MIDI device to associate the sustain with whatever notes are still active.

Some of the Yamaha pianos have several pianos emulated and selecting a "Grand" will sound different than if you select an "Electric" or "***** Tonk" setting.

There is NO internal adjustment for this. other than the voice selection. Choose either the Grand1 or Grand2. Do not use reverb as this can "ring".

Piano has a ringing sound when playing keys


Check if the sustain is stuck on due to a bad pedal or lack of.

Also some settings like Harpsicord have a sound that has ringing... check you have the correct voicing.

Midi vs. Sound


Think of MIDI like the old time player pianos where you put a roll into it and the punches on the paper roll told the piano what notes to play. MIDI is a way for computers and musical instruments to communicate what is being played. When you plug your keyboard into your computer and enable it in Cakewalk, then Cakewalk records what notes you are playing on your keyboard (makes a piano roll file). Then when you tell Cakewalk to play this file back it communicates to your keyboard and says play these notes just like a person was sitting there playing these notes. The distinction here is you are recording and playing back your performance (which keys you pressed, how hard you struck the keys, how long you held the keys for sustain, etc...). No sound is actually being recorded, just the PERFORMANCE. When you play it back, the keyboard regenerates the sounds on the fly just as if you were actually sitting there performing the music again. Same thing applies to other MIDI enabled instruments (drums, guitar, saxaphone, etc...). This opens up all kinds of possibilities, you can redirect the recorded MIDI file to a completely different sound or instrument. Example... you record MIDI of you playing piano song, then you have Cakewalk play this MIDI back to your keyboard but you change the sound on your keyboard to guitar, it will play the same song, but now you will hear guitar instead of piano. Get it?
