Hi all! Have some problems with my mini.So first off my Pot for OSC 2 was all over the place jumping pitch up and down and overall bad sound.It was not used for some time due to living abroad so guess it got stuck with dirt.So i opened the mini up and desoldered the pot 5 k linear one,cleaned it with isopropanol put it back together and it is working smooth now.Although my problem now is when i push a key on the keyboard some keys upper tone part mostly,it’s glissing up and down but only when i push the keys loosely,in full bottom it’s ok.It’s like this i am playing from lower octaves moving upwards then this glissing pops up in between notes going upwards but never from going downwards from upper parts of the tones.The overall pitch is spot on overall and it does it on all oscillators the same.It’s like having the glide on max but holding only one key down the pitch swings up and down.It’s always when i release or press the the keynever when holding it firm in the bottom,there is a between moment from bottom to releasing it,there it starts to move pitch up and down never when i have the keys fully pressed down.If i’m playing and pushing the keys fast and firm up and down but slowly in between to the next notekey it’s np.I have tried to clean most connectors not helping at all.My keyboard bushings etc looks in great shape.I am about to leave it to someone but it feels like a connecting issue or something maybe glide pot or switch? It makes the same sounds as the glide movement between keys but more irregular up and down and backand by holding one key only.Hard to explain but basically it feels like something between holding a key and letting it go in between that it starts.Regards any help or thought i am happy to hear it.
Did some serious cleaning on the single busbar the one regarding pitch.And also cleaned and took on and off the cinch connectors several times.Well something worked i figure it was some keys on the contacts leaning on the busbar that was dirty.Happy again mini again !!
It is called “squirrelling” and is common for dirty busbars and misaligned contact springs.
You need to service the keyboard contacts board… carefully..!
