Program Hangs on Repeat Send To Device commands

[gary-1959]

I was having a problem with the program hanging after a couple of Send To Device operations.
I found this about mido: mido/mido#37 which talked about only receiving 1000 messages before input hangs. Following the discussion I inserted a sleep command into AlesisV25Device._send (line 26 in alesisvsysex>device>alesis.py) as follows:

def _send(self, message):
if not isinstance(message, SysexMessage):
raise ValueError("Can only send a SysexMessage")
p = mido.Parser()
p.feed(message.serialize())
self._port.send(p.get_message())
time.sleep(0.001) # added because of save to device hang

Of course time has to be imported beforehand.

This seems to have resolved the problem.

Hope this helps,

Gary
