3-Channel Mono, 1-Channel Stereo CV Click-Less Mute

ONCE IN A WHILE is a 3-channel mono and 1-channel stereo mute switch with CV control. Any audio or CV signal fed into the IN jacks and taken from the OUT jacks can be muted and unmuted with a latching MUTE button per channel. If a channel is not muted, you can also mute it momentarily with the dedicated STRIKE button. Conversely, you can unmute a mono channel with the same STRIKE button if it is muted (this is not possible with the stereo channel). LEDs indicate whether a signal is being passed.
You can also use CV signals to mute channels. Just connect a gate, LFO or envelope to the CV inputs and the channel will be muted from a voltage of about 2 volts. Even if you apply a control voltage to the CV inputs, you can mute the signal with the MUTE (latching) or STRIKE (momentary) buttons.

The first input is normalized to the other inputs. Therefore, you can also use ONCE IN A WHILE as a 1 to 4 buffered multiple with individual mute switches. ONCE IN A WHILE was designed to provide click-free muting for audio signals, but has become much more performance-oriented with the addition of momentary STRIKE buttons and CV inputs.
