Screenshots are from a Galaxy Tab S8+ (2800×1752). Control names in the text
match the labels on screen.
The screen has three parts that are always visible:
To the left of the tabs is the PART A / PART B switch. These are two
independent layers, each with its own oscillators, filter, envelopes and LFOs.
The switch is active on the OSC / FILTER, ENV / LFO, SAMPLE and MODULATION
pages; on ARP and FX it dims, because the arpeggiator and effects are shared.
further out, the smaller the step. This is how you land a filter sweep on a
specific note.
Bipolar parameters (Pan, Fine, Amt, Tune) fill outward from the centre, so the
sign is obvious at a glance.
