Count me in - I need high definition ADCs. This looks very promising.

Not sure about the APC40, but Alesis Ion and Micron have these, as well as Akai Miniak (rebranded Micron). The feel is very nice for fine tweaking. I have been looking after these for a while: www.instrumentalparts.com in the US ships replacements wordwide, but it's not too cheap (part no. 0-09-0044 for Micron, 0-09-0036 for Ion). If you google around with the part numbers, you might come up with other stores as well (there is www.disco-store.at in Austria, but they don't ship abroad). Some Numark devices might have these as well, but I'm not sure... To read those endless pots you need two ADC-channels/pot and use some logic to eliminate values within each channels electrically inactive zone. A15-3P from Piher might also work, but I don't know where to get one. Anyway, I am going to do some experiments with "endless pots" and MIDIbox as soon as I get my hands on some. Will let you know. If anybody knows where to get for example #0-09-0044 cheaply (or happen to live in Austria, willing to trade with me...), or has prior experience with these, I'm eager to hear.
