Roland System 100m

hi there,

i got a system 100M recently and tried to play it via my doepfer MCV4
maybe i am stupid, so excuse me, but i dont get it to work

the OSC plays out of tune, means if i tune it to 440 the octave isnt proper
the notes got more out of tune the higher they are (its about 15% per octave)

I dont get the gate properly conected, so the notes dont stop until another note starts

help is highly appreciatet!

thx, ringo.fire
