Hi, there are some bugs I found when trying to use the matrix~ object.

First, in Max, when in mix mode, default ramp time is 10ms, in Pd we have apparently "0", which is bad because it clicks.

The clear message should take into account the ramp time, but it doesn't, so even with a big ramp time, it'll click. Moreover, it doesn't seem to work properly because it'll stop the sound, but it won't clear in fact the connections - so lets say you had something on (amplitude of "1") and then cleared it, you can still send an off message (amplitude "0") to it and it'll consider that channel was on, so it'll click back to "1" and come back to 0. In Max this doesn't happen, because clear acts like muting and setting it all to 0!
