Re: [CAD_CAM_EDM_DRO] Joystick connections

Hi Brian,

Thanks for the URL's. Funny thing this midi stuff just came up. My
youngest son (senior in HS) just grabbed my Ensoniq keyboard, and an old
midi extension cable I made up, and is making tracks for his animated
film strip. The good side is, I get his old slow, 400 Mhz Pentium II
(?) ! So now, after I find some PC100 SDRAM, I might have a new PC for
EMC!

Using the MIDI channel might be useful! Let's see what you come up
with!
