Re: [Lmuse-developer] Fwd: RE: [Lmuse-user] unsolicited midi muting

Hello,

the events
         <event tick="88565" type="1" a="262145" />
         <event tick="88565" type="1" a="7" b="110" />
should be ok. The first is a controller event which sets
HighBank LowBank and ProgramChange to zero (missing b parameter
defaults to zero). The second one sets Volume to value 110. 
Note that controller events (type=1) do not have
a len.
Not all external midi gear can handle HighBank and LowBank. My Korg
NS5R is silent after sending it a HighBank controller value of 0.
