Voxengo Tempo Delay 2

Tempo Delay 2 is a stereo delay effect with separate multi-mode filters and tremolo effects in each channel. The control scheme is somewhat unusual, as it features an internal BPM setting (which can be freely adjusted or synced to the host application’s tempo setting) in addition to the Delay and Rep Period controls in both channels. The Delay parameter sets the initial delay time, whereas the Rep Period control determines the delay speed after that.
The built-in filters are quite aggressive, with rather wild resonance which sound great when combined with longer feedback times. Changing the BPM value while the delay is active results in a smooth pitch shifting effect which can be put to good use in a variety of sound design scenarios.
CTRL + drag will simultaneously change the same control parameter in the left and right channels, whereas CTRL + double click will set the clicked parameter to the same value in both channels.
