8HP Triple Resettable LFO with Clockdivider

Tryfelo has three LFOs that can be reset by a single clock/trigger signal. Each LFO produces either a triangle or a square wave selectable via switch. In the mid position of the switch the LFO is deactivated. You may change the LFO´s rate with the help of a dedicated potentiometer. There are also CV attenuators per LFO available. Three bipolar LEDs are indicating the current state of the voltages.

The LFO rate available increases from LFO 1 to LFO 3. LFO 1 will produce fast oscillating waves, whereas LFO 3 will provide very slowly changing control voltages. LFO speeds may be changed individually by choosing different capacitor values during assembley.
Each LFO is internally connected to a clockdivider that will reset the LFO cycle in connection to an incoming trigger/clock and even holds the LFO value when the clockdivider pulse is high. During a hold phase there is still a slow movement in voltage on LFO low rates to keep a pause interesting. This way you can connect the LFOs to a rythmical context and create pauses in a very musical way.

The clockdivider needs a trigger or clock signal at the CLK input, that will be converted into a pulse to create these pauses/holds mentioned above. The length of the pulse depends on the speed of the clock. Slower clocks or clockdivisions will create longer pulses. The incoming trigger/clock signal will be divided by 2 or 4 for LFO 1, by 4 or 8 for LFO 2 and by 8 or 16 for LFO 3 selectable via switch. The LFO reset may also be deactivated by setting the dedicated switches to the mid position. Each divided signal my also be taken from the individual clock outputs for further external processing.
The REST input will accept any trigger/pulse/clock singal and resets the clockdivision for all LFOs. VARI accepts any control voltage and produces rythmical variations of the clockdivisions. These variations are not purely random, but will generate alternative trigger patterns in connection to the incoming clock/trigger signal.
