Erica Synths Pico VCO is a great, deep sounding VCO with 32 selected waves – classical, fattened with sub-oscillator, FM synth and others.
2 banks, 16 waves each
Voltage controlled wavesurfing
Wave morphing in LFO setting
Typically you would need several rather expensive modules to generate similar sounds, besides there's an extra feature – flip a switch, and you have a versatile LFO.
