# x42-scope(1)

JACK/LV2 Oscilloscope

## NAME

x42-scope - JACK/LV2 Oscilloscope

## SYNOPSIS

**x42-scope**

## DESCRIPTION

x42-scope is a four channel oscilloscope for use with the JACK Audio Connection Kit.

It is equivalent to using the 'http://gareus.org/oss/lv2/sisco#4chan' LV2 plugin except that it is a standalone version, not depending on any LV2-host.

x42-scope/SiSco implements a classic oscilloscope display with time on the X-axis and signal level on the Y-axis. The minimum time-scale is 50 micro-seconds per grid, yielding a maximum resolution of 960kHz at 48SPS.

## USAGE

x42-scope takes no options. It can be closed by sending a SIGTERM (CTRL+C) on the command-line of by closing the window. All control elements are operated in using the mouse:

- **Click+Drag**

  left/down: decrease, right/up: increase value. Hold the Ctrl key to increase sensitivity.

- **Shift+Click**

  reset to default value

- **Scroll-wheel**

  up/down by 1 step (smallest possible adjustment for given setting). Rapid continuous scrolling increases the step-size.
