I don't know how useful it is to just post tips, since I don't know what people actually need. But this could be a place for answering urgent questions.
Anyway, my two cents is a tip for using chromatic tones in voltage sequencers. In VCV Rack, CV control uses the one volt per one octave standard. Voltage grows linearly with pitch (logarithmically with frequency). This means that a single semitone is equivalent to a difference of 1/12V. Middle C is equivalent to 0V, and the voltage of each pitch in volts is its distance from middle C in semitones divided by 12. You can use the same principle to transpose pitches by adding signals.
