Polyscope adds a four-channel oscilloscope and tuner to the Poly Effects Hector. It installs as a module with its own full-screen interface, measuring up to four signals while passing each one straight through to its output, so audio and CV can be watched without leaving the patch. The scope offers stacked, overlaid and XY views, adjustable timebase and voltage scale, per-channel AC or DC coupling, auto, rising, falling and roll triggering with holdoff, persistence, cursors, autoset and freeze. Frequency, peak-to-peak, RMS and period readouts sit alongside a min/max envelope that shows signals too fast for the trace. A separate tuning page shows note names and a cents meter for all four channels, with an adjustable reference pitch. It installs from a USB stick on the Hector firmware release it targets, and a separate recovery stick removes the additions.
