Note Hangs when using MIDI In block.

[Former user]

The MIDI block has arrived in the mail and I went straight to testing it. Sadly, it occurs quite often that a note "hangs" and does not stop playing; only turning the Patchblock off helps to "fix" this. It happens regularly when playing directly from my Akai MKP25. I appended a MIDI recording that reproduces the phenomenon (consistently!) when playing it back from Ableton. It also happens with my optocoupler circuit. I could reproduce it with multiple Patchblocks, using the Polysynth example provided in the 0.4 release.
