they suffer from cracked solder joints as the solder is the mechanical strength on the output jacks when you fit normal jacks in they act like a lever and put pressure on the solder joints from gravity eventual they crack you then have to resolder them then they work again and make sure you use 90 ...

sounds like a bad psu they use external wallwarts and if left on all the time even when the korg module is switched off you need to switch of at mains also they get hot and b ecause there is no load can over heat which makes the dc bad with ripple and why you get the sound degredation

its also a known problem that the dual linear volume control sliders fail and if its also on the phones i would suspect this if the diagnostics dont work the trinity does have floating phono,s the only mechanical protection is the solder pads and they do fail due to phono leads i fit 90 degree phono ...

also the t series use dshd disks

because of the 1mb pcm

the korg 01w went back to dsdd

1 t3ex dont do pcg they use the older method pcg came a lot later in the n series the only way to do those file is to image them with omniflop in the pc there are 2 types of format options on the t series with the ex theres just all program data times 4 and and sequencer data and there is pcm data ...

check for cold solder joints on the audio outs as they can crack and can be intermittent this happens to all korgs as they rely on the solder joints as the mechanical strength i recommend the 90 degree phono 1/4 inch jacks as they dont put so much strain on the sockets where as the straight versions ...

i dont have an m1 but have a t1 and t3ex

similar patch creation but less multisounds

i create a lot of user content on my t series and trinity using my own multisounds

the o1w is the first ai2 synths the m1 and t series are ai1 versions the t series with pcm sample playback can have 48khz samples most samples are done in 32khz as it allows 1 sample per octave with the t series you can do a 1mb multisample this allows very good quality sounds the ai2 series used a ...

all fatar are the same height and circuits connection

the waterfall keyboards have squared of keys so its hard to use them but you can use the hammer type to as used in the k2500x and the ensoniq sq2 and ts12

there zero ohms resistors they can be replaced with insulated wire links

that picture you have i noticed it has a bad spring i would change that if i was you

you will find that the weighted versions went into dearer keyboards

what was wrong with your keybed

sounds like ripple in the psu check the ripple with a scope if its to high

with the service manual recommendation for max ripple change the filter caps

check that the battery has not leaks as it destroys ic and tracks and if there is green oxide on the tracks and white powdery blotches then you will have battery leakage you need to use some white wine vinegar to neutralize the acid then wash with water remove all ic that are damaged and check that ...

current price is £1000-1400

depending on quality and if it has midi or not

you need to service the psu as its sounds like ripple in the psu filter caps they are failing and why it gets worse over time as they stop charging and discharging the voltage sand let the ac ripple through from the rectifiers a sign that you already had burst caps is a good sign that others may ...
