I'm using all the individual oscillators available to me here (a grand total of four, since there are two complex oscillators -- the 259e and 261e). While I'm using them as individual voices, the modulation oscillators are also modulating the main oscillator (pitch/FM on the 259e and timbre on the 261e). This modulation is being affected by position on the main keys as well as the X/Y pads of the K-controller.
Musical parts are controlled by the 251e providing a trio of very short sequences selected by the K-controller, a "split" setup of the K-controller's long keys, for the hand-played bass and melody parts, and an arpeggio controlled by the K-controller's arpeggiator.
Obviously I need to work on this a bit more to get timing and movement down. I'm also hampered a bit here from time to time by the fact that as I play my hands get a bit sweatier and this causes some stiction on the keys the longer I go. That's not going to change, so I just need to learn how to deal with it.
