Hi,
 
I'm a beginner using PD as a realtime MIDI processor, and with the help of this list, I've been able to prototype my application in just 2 short evenings.
 
Now, I'm looking to make my app as tight and fast as possible.
 
I've used the minimum amount of code whenever possible -- it's probably not as elegant as it could be, but there are no apparently obvious gas-guzzling portions of code.  (It does use 2 subpatches, I don't know if those are slower or not.)
 
Also, since the app does not require audio processing, I used the -noaudio flag.  I tried using the -nogui flag but it doesn't seem to work at all then.
 
Here's a link to the app if anybody wants to take a quick glance at it for any glaring problems:

...and download rsmidi.pd.
 
Thanks,
