Good effort making your own controllers and sequencer, which is an achievement in its self for your first year. If you have any questions be sure to post them or jump into the chat area as there are people here also into the DIY field.
There's a bunch of us in chat who've been having a look at your sequencer and from what I've seen it is looking real nice. I especially love the audio filtering tools. I'm sure this idea will make it's way into a couple of commercial alternatives
What part of Florida are you in? Dont stress the as nice as yours statement too much. Some of these guys have been at it for years and they have displays that rival or better huge commercial companys, heck some of these guys do those displays! Myself I had a whimply little 32 channels last year, but every night I would get home and just watch in amazement. Take your time, info is everywhere and if you need help a new question is only a few clicks away!
