Blocking Oscillator (Sperrschwinger) as a kind of analogue freq dividing

TSt's icon

in the title is desribed for what kind of circuit (patch) I've been looking for

in my remembrance, I thought about this variant of frequency-dividing, when valves-circuits e.g. where using in organs and similar instruments like emp1 (ionika) philicorda(Philips)...

we don't need and want realisations under Gen this circuit, patch should be work under Max ver.4.6 too

thanks for help and suggestions
