Correct, since it is bitimbral there is one sequencer per layer. You can get some really fun poly rhythms going by using the poly sequencer on one layer and playing the keys, or using the arpeggiator or gated sequencer on the other layer. Between that and either linking or keeping the two layers separate for live editing there are lots of possibilities!
Nice!
Can you be a bit more precise about what you mean with polysequencer and gated sequencer (in comparison with the Pro2 and its 16 tracks whereof one is for notes)? Just a question of wording I guess...
I suppose it is meant: 1 track for notes in polyphony + 4 tracks for modulation of params. Those 5 tracks being available in each layer. Correct?
The poly sequencer is only for recording notes, i.e. melodies or chord sequences. You can input the values directly via the keyboard by just playing what you wanna hear in the end and by adding ties and rests where necessary. So in that sense the whole poly sequencer is slightly comparable to the first sequencer track of the Pro 2.
The gated sequencer operates like a modulation source with four tracks. You can also assign the tracks to the oscillators' frequencies, but not by playing the according notes on the keyboard. You'd have to enter the relative values step by step in the according gated sequencer menu. This is the way to go if you want a sequence to be transposed immediately btw, as the gated sequencer deals with relative note or rather frequency values, not the absolute ones you pressed on the keyboard. So instead of playing back an octave jump between C3 and C4 by default for example, the gated sequencer will only playback the information root note and one octave higher.
Apart from that, you'll be able to modulate pretty much every parameter with the gated sequencer, i.e. filter cutoff, envelope times, LFO speed, etc. With sequencer tracks 2 and 4 you will also be able to modulate the amount of slew for tracks 1 and 3 respectively.
To avoid one misunderstanding though: There won't be 5 sequencer tracks available for each layer. You have to choose which sequencer mode you'd like to use. The gated sequencer can't be run at the same time as the poly sequencer does and vice versa. You can, however, program both per layer and switch between them which makes for twice as many variations of the same layer.
