RD-700SX sustain -> noteoff bug?

[tuomas2]

Hi!

I have Roland RD-700SX. I have been suffering of the following problem:

Sometimes, when sustain release is right after noteon event, the note
is cut off although it should remain because key is still pressed down.

Here is an example midi file of this behaviour: http://users.jyu.fi/~tuma/rolandbug.mid
First time it occurs to D2 at measure 9 and then many times to C2 starting from measure 13.

I am curious if someone else have faced this problem on RD-700 series pianos and if
there is a workaround etc. I have the latest firmware (1.07) installed.

This is really frustrating behaviour and it keeps coming again and again.

Best regards, Tuomas
