Frequently Asked Questions
It's not as rock-solid as some modern digital oscillators, but Doepfer’s design minimizes drift for analog performance – expect some slight drift over extended periods.
Absolutely, the lower tuning ranges make it suitable for LFO duties, though its waveforms are fairly basic compared to dedicated LFO modules.
Position 1 offers a wider range for experimentation; position 2 is better suited for sub-bass frequencies and tighter, more predictable modulation.
