If you've played with the sequencer in Korg’s iMS-20 app you have a head start on getting to grips with the one that’s included in the iPolysix. Like the iMS version, this one provides a combination of drum and synth tracks, with the former based on samples generated by the synth in play (in this case, a slight variation on the iPolysix itself).

The drum synth version ditches the arpeggiator in favour of an additional effects processor with sensitivity and attack controls. Though the intention is for you to create rhythmic parts, you can also use the drum synths to create pitched synthesizer sounds for a full eight-track synthesizer ensemble. You can have up to six drum tracks in a sequence and two full-blown synthesizer tracks.

Both synths and drum synths are loaded with factory sounds to get you started. The sequencer is a pattern/song-based thing, with each pattern capable of storing up to 64 steps. You can play the pattern forwards, backwards, on only the odd or even notes, every third note, or in random order. You can have up to 32 different patterns per song, up to 100 measures in length. Enough for a full electronic production, in other words.

Synthesizer (but not drum synth) parameters can be automated. Tapping and holding any parameter brings up an automation grid up to 64 steps in length, into which you can draw your parameter values for a given step. This applies to any parameter, even things like MG sync and waveform selection. Better still, it applies to the effects, both the synth's and the mixer section's. Sweet.
