[sdiy] Easy expo VCO suggestions for seqencer's LFO clock..

[Tom Wiltshire]

I’d use one of my PIC-based LFOs. They have exponential control that could be easily be arranged for 1V/Oct with just a voltage divider if that’s crucial (0-5V CV covers 8 octaves on one of them, IIRC).

Alternatively, in these modern days of plenty, you could use a 3340!!
