Poly Switch

Overview

Poly Switch allows per-channel switching of the sixteen channels in a polyphonic signal. For convenience, there is a button to turn all of the channels on or off en masse, as well as one to toggle Solo Mode on or off. In Solo Mode, only one channel can be on at a time.

For convenience in working with Poly Switch, each channel displays a green LED when that channel's input from the In Jack is non-zero.

Poly Switch can accept polyphonic CVs, switching each channel on when the CV level for the channel exceeds 2.5 Volts, and switching it off otherwise. If the BLink In Jack is connected to a BLink source, its BLink Modified Threshold signal (pin 3, zero-based) replaces the 2.5 V system truth level. (See the Boolean Truth module documentation for more information.) There's also a button to defeat CV input without removing the input cable.

Ordinarily, changes in on/off state are declicked to help prevent the introduction of spurious harmonics that will be heard as pops and clicks. However, for certain CV signals it may be preferable to pass the signal as-is; the Declick button provides this capability.

The help you're currently reading is always available within the module by clicking on the Cyberwerks name at the bottom of the module; it can also be reached by pressing Ctrl-H (Windows) or Cmd-F1 (Macintosh) when the module is selected.

Controls

• The Channel Toggles 1-16 turn the appropriate channels on or off. If in solo mode, only one can be pressed at a time.
• The All/None Toggle can assume either of two states: All or None. Pressing it when it displays "All" turns all channels on, whatever their current state, unless the CV In Jack, which takes precedence, is populated. Pressing it when it displays "None" likewise turns all channels off, unless the CV In Jack is populated. Either press has the additional effect of terminating Solo mode, if it's active.
• The Solo Toggle turns Solo Mode on or off. In that mode only one channel at a time can be on.
• The CV Toggle enables/disables input from the CV In Jack (see below).
• The Declick Toggle turns signal declicking on or off, helping prevent the act of switching a channel on or off from inserting spurious transients into each channel's signal.
• The CV In Jack accepts sixteen control voltages, one for each channel. A signal strength greater than the truth threshold (2.5 V natively, but see the next entry) switches the channel on, while any lower signal switches it off. Note that these are continuous CV voltages, not triggers.
• The BLink In Jack accepts the output from a Cyberwerks Boolean Truth module (v1.2 or later), using its pin 3 signal (modulated threshold) to set the truth level used for CV control of channel switching. Note that since this signal can vary, so can the use of the CV inputs, allowing for some very subtle effects in patches.
• The In Jack accepts polyphonic input, while the Out Jack sends the switched polyphonic output of the module.
