Hi,
I'm using Copperlan on OSX Yosemite with AL-88. When using the Soundtower Poly Evolver sound editor and its "Morph" feature the AL-88 goes funny.
This morph function must send a batch of sysex very quickly and as a result the AL-88s MIDI out light just periodically flashes and when I try to play notes the Poly Evolver doesn't receive any notes. If I press the reset button on the front of the AL-88 it then starts to work again.
This is most annoying and severely limits the usefulness of Copperlan for me.
