Sebastian,
I must have made a mistake. I don't have any close up shots of the Buchla
291 panel. I based my assumption that this VCF doesn't have a resonance
control on the schematic, which seems to indicate that there is a resonance
trimpot, but makes no mention of a front panel control.

: Hello SMOGers,
:
: Got a question about the Serge variable BW filter. I noticed that there
is
: no resonance control on this filter (same as on its predecessor, the
Buchla
: 291 VCF). Is there no need for that since you can sweep the bandwidth?
I'm
: assuming that sweeping resonance has a similar effect as sweeping
resonance,
: but can someone clarify that for me?
: Seeing filters without resonance controls makes me nervous.

The Buchla 291 dual variable bandwidth filter is resonant. It is a vactrol
design by the way just like the 292 lowpass gate and other 200 series
modules.
