How to use MIDI and Arduino without MIDI to USB?

So, in short terms, with an arduino, and nothing else, except inputs, take one of those inputs and use that to send MIDI interface codes? The MIDI library goes over hardware serial and requires a MIDI to USB cable. I want to build a crescendo pedal with some stops for a Hauptwerk organ. I've already got my keyboard on it, too. You should check it out.
Most any help appreciated,

I don't understand why you think you need a MIDI-to-USB interface to get MIDI out of an Arduino. The MIDI library speaks MIDI (which is a serial protocol). Does your destination device have a 5-pin DIN MIDI input?

I want to interface the MIDI directly with the computer, unless my Yamaha PSR-260 has mIDI Thru...

Hope johnwasser doesn't mind me jumping in here, but your Yamaha has MIDI thru (MIDI IN and MIDI OUT). Page 52 of your manual.

So then how would I route this extravaganza?

MIDI is a daisy-chain deal, you connect the MIDI OUT of one device to the MIDI IN of another device. Eventually the MIDI OUT of the last device should connect to a computer or a sequencer.

Sorry if I sound dumb about all this, but with the MIDI library, how would I get to make it send commands aka the crescendo pedal/stops to my computer? I'm quite new to the internal workings of MIDI...
