Hi Arnauld, Sorry if my last post was unclear but I just re-read your message and I get it now. The multimode filter in this case, is being used as a sine wave oscillator. There is no VCO in the line up - just the output from the filter going into the comb filter. You could use the RS95 sine out for this purpose but I made this patch pre RS95 so hence the filter being used. Regards Dav
