Takaab VCO-3340 - Analogue Voltage Controlled Oscillator Sequencer The HPF-3320 can be set

The HPF-3320 can be set to 2 pole or 4 pole mode and it has attenuated CV control over cutoff frequency and resonance

In this respect the 4NOT can work as a buffered logic multiple

trigger or gate) at the TRIG IN will move the internal sequencer along by one stage

but should already be trimmed to +/-5V when it ships

Takaab VCO-3340 - Analogue Voltage Controlled Oscillator Sequencer The HPF-3320 can be setA stable, reliable analogue VCO with a rich warm sound. The design is based around the AS3340 triangle core oscillator IC which itself was based on the legendary Curtis CEM3340. We have ironed out the quirks of the AS chip so it now sounds and behaves just as good as the CEM3340. The addition of an 11 pole + 5 octave switch makes it useful and reliable as a live VCO. The center position being approx C1 means it can be pitched down well into down into
