[quote name='Geek99' post='850927' date='May 29 2010, 09:32 AM']I have the sr16- it can hold several drumkits, but you can't associate them with songs or patterns so switching to the right kit is manual operation.[/quote]
Er, yes you can!
By default, each pattern has an associated, assigned drumkit. But you can tell it to ignore these assignments and retain the currently selected kit regardless of pattern changes.
This is in SET MODE, which can be PATT (kits assigned to patterns) or MANUAL (the current kit applies to all patterns).
I love my old SR16 and use it a lot. Live even, without a drummer, it's superb with 2 footswitches controlling start/stop, fills, A/B switching - outstandingly easy to use.
I bought an SR18 shortly after they came out, expecting to drop the SR16 like a stone, but actually, although it's got a few new stonking features, there are quite a few things different from the SR16 that make it less good in my mind, which is a real shame. So my SR18 is sitting unloved on a shelf while the SR16 lives on.
