EFM LFO 5AThe last module of the first cabinet i built.

(Click image for FPD-file)

This voltage controled LFO is realy a versatile baby. It features
- tri, sqare, saw
- 8 step staircase
- noise source
- sample & hold

Unfortunately i never get the s/h to sample and to hold. So i took Peter Grenaders LF398 based s/h circuit, combined it with Ken Stones pulse2trigger circuit, etched a daughterboard and had fun since then...

The whole story of this LFO (errors, modifications) was documented in the old EFM forum. I scanned the printouts i kept (see link below).
