Throb free clock by shaduzLABS

Throb is a free clock VST, VST3, Audio Unit plugin developed by shaduzLABS. Compatible OS(s): Windows 64b, macOS.

Throb is a free and open source plugin that generates clock/reset signals synchronised with the host tempo. It is currently available for Windows (VST2 and VST3, 32/64-bit) and OS X (VST2, VST3 and AU 32/64-bit). The multiplier is an automation parameter and therefore can be controlled using the respective host functionality. Both the multiplier and the resolution (ppqn) settings are serialized to the preset chunk.

You won’t need a DC coupled audio interface, but please avoid sending the output of the plugin directly to your speakers/headphones.

Clock Jitter

ZynAddSubFX free software-synthesizer by paulnasca 2

Clock Jitter is a free clock VST plugin developed by Voxengo. Compatible OS(s): Windows.

This VST plug-in was designed to be a “mastering” plug-in. It emulates an effect that is common on some old ADC (analog-to-digital converter) devices. This effect is called ‘clock jitter’ which arises when internal ADC’s wordclock is not precise. Actually, it is unknown whether this plug-in is usable for sound production or not, but in some situations this ‘clock jitter’ noise can be applied rather productively.
