Not yet, but it will before long.
The primary function of the ck patterns was to support polyphonic drum
patterns.
I worked through a few different ways of doing those, starting with
variations on the P3 pattern format, but ultimately decided that the event
list was probably the most efficient way of doing it.
Plus it had the added advantage of handling poly keyboard parts with
controller streams.
The OS so far has had most of the effort in ck patterns geared towards
percussion programming via grid edit.
There is an event list editor, but it isn't as functional as the MPC one.
In fact, I'm looking at re-writing the event list editor to make it more
like the MPC, after having played around with an MPC60 for the first time a
few months ago.
At the moment you get one big list, like in Cubase. You can step through it
by bars, but it can be tricky to keep track of how bar, beat and tick
numbers relate to the equivalent 'step' positions in a P3 pattern.
The MPC method of showing you the events within a single step worth of time
will fit the Cirklon user interface better.
