Frequently Asked Questions

They are deterministic oscillators; they're repeatable unless external modulation is applied, which is typical for vintage-style LFOs.
The frequency range is fairly standard for older modules; newer designs often offer much wider ranges, but this provides a useful, classic modulation scope.
While they don’t have built-in synchronization, you can use external clock signals to modulate their frequency controls, effectively syncing them.
