Hot to make a programmable looper

[jakehop]

Hi guys,

How would one make something like this:

http://cgi.ebay.com/Analog-TRUE-BYPASS-WOBO-Prog-Looper-programmable-30-off_W0QQitemZ230332401275QQihZ013QQcategoryZ22669QQcmdZViewItemQQ_trksidZp1742.m153.l1262?_trksid=p1742.m153.l1262

I understand how the dip-switching contra the activation of relays work. However, how can I make something that either turns one preset off when another is selected, or adds that preset? Do I need to use a micro controller, or can this be made with logic?

Any thoughts are highly appreciated!

Kind regards, Jake

The circuit has been posted at GEOFEX for years. Look for a programmable FX switching system, then go see figure 7.

What are we up to, about two weeks between this question popping up again?

Sorry for this, but I looked through your site - there isn't a direct link for it. When I Googled it the last time, I only found a link to your "SpiderFX" project, that doesn't seem to reflect current thoughts, as it is missing most of it's images.

Not to sound rude, but if there is a link on Geofex for that article, please tell me where. I even put on my glasses for this one, and they usually never come out of the drawer. Now that I know what to search for, I found the article. Thanks a bunch for the information, it's EXACTLY what I need! I sincerely don't want to sound ungrateful, but please check if there actually is a link on your site to the article.

Kind regards, Jake

As I said, I found it now that I knew what to Google for. I was asking for a link on the web page. 

Kind regards, Jake

It's there. On R.G.'s main page. In that big table. It's:

Aye. Right there on the front page - how can it be that hard to find?
