Thanks Ted. The WK-7500 Pattern Sequencer permits expansion of each part (Intro, Normal, Variation, etc.) to 16 measures. If you're writing in 4/4 and you select the WK-7500 8/4 time signature - then you get the equivalent of 32 measures at 4/4. This time signature manipulation is a hidden benefit. There is a very small compromise in tick granularity, but it's very little. Ostensibly, each Pattern Sequence can be extended to 128 4/4 measures (by selecting 8/4) and you get 100 slots in which to save them. There are probably more latent benefits hidden in the Pattern Sequencer. My application is to write all the accompaniment (drums, bass, piano, synths, orchestra, etc.) and then play along for fun. Great experimental tool for exploring fresh ideas.
