Feed the oscillator output to a window comparator (like the PlanB model 17 triple timer). Connect the output of the FlipFlop to the FM input of your oscillator (if you have the Mono Lancet dock). One way is to input the sync trigger to the Intellijel Flip/Flop module's SET input. So, I was thinking I could either add another oscillator with hard sync option, or find a module that forces the lancet's oscillators to sync. The modular dock spits out two separate oscillators, which can be routed back to the filter, pre vca.

You have to put a JFET directly across the cap, and then feed the gate of the JFET with a comparator which is normally at the negative rail (which keeps the JFET open and the integrator cap working normally) but which goes to ground with the sync master signal's rising edge to close the JFET, thus short-circuiting the cap. It only requires access to the capacitor itself. If it is a saw core oscillator, then it is actually pretty easy to do. Depending on the type of oscillator, it may not be that difficult. It requires a kludge directly onto the oscillator's circuitry. Sketch-n-Etch wrote:Hard sync requires short-circuiting the timing capacitor in an oscillator's core. However, any such changes will almost certainly invalidate any warranties.ĭr. I'll need to see your schematics and preferably a picture of the PCB. PM me for instructions, if you wish to know how. If it is through-hole, then it will have to be kludged underneath, or directly onto the leads. If the cap is SMT, then there is a chance that the JFET can be installed on top of it.
