[sdiy] Unique sounding modules that can't have voltage control?

[cheater cheater]

Hmm so let's try to narrow down the question

What are circuits where:

1. the circuit is available as a modular synthesizer module, or a
similar subcircuit in a non-modular synth

2. the module has a resistive potentiometer or slider on its front panel

3. the module does not have a cv input for the same control

4. adding a cv input is either impossible or would change the sound of
the circuit in an important way
