with 4 note polyphony, Pluck is also a useful source of chords: with Decay high and the output into a closed vca run 3 or 4 fast notes into it (trig/v-oct) and then open the vca with a short a/r envelope either alongside the last trigger (to keep a bit of the pluck sound) or shortly after (for a more classic synth stab) or maybe even a bit of both. 2hp Brst is a good partner module for this.
