Random Sample and Hold LFO with sync

Hi to you all, I have searched the Forum for this and haven't found anything that would help as yet. I am trying to add random sample and hold to an LFO I am making. I want it to be MIDI syncable as well. When I say "Sample and Hold" , I mean the sample source would be something like white noise (or pseudo random noise I guess - yes?), although being able to sample any modulation source at my desired LFO frequency setting would be useful too. That way, a ramp oscillator would perhaps become big 'steps' for example, in other words I am not looking at high sample rates here 🙂

I have crudely managed to sync my LFO speed by reading the VST host tempo and converting the value obtained to a frequency for a standard SM oscillator. The thing is, after a few bars the LFO 'sync' slips out of time, so I then added a reset pulse to occur every 4 bars or so - a band-aid fix! - but which did have the added bonus of allowing me to start the LFO cycle at any point. This kind of works but I think there must be a better way.

The random sample and hold has me beaten at the moment though.

Can anyone point me in the right direction? I am a newbie but I am trying very hard to learn 😕

    Open it in SynthMaker?

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
