New OCTOLFO, Multipass, & Resonator Eurorack Modules From Tiptop Audio

Also see Buchla & Tiptop Audio 248t and 230t Incoming for new details. As always, check with dealers on the right for availability.

Details on the OCTOLFO, Multipass, & Resonator follow.

OCTOLFO – Eight-Voice Voltage-Controlled LFOs

For all Eurorack users, here comes your mega LFO. And for those of you who have already joined us on our journey into polyphonic patching heaven, this is the one you've been waiting for. The Octolfo consists of eight fully independent LFOs with plenty of controls, lots of waveforms, and the ability to load your own waveshapes. Clock-sync it or let it free-run. Use one-shot cycles of waveforms to create unique envelopes, and reset LFO cycles from your notes. All eight LFOs are available simultaneously on regular jacks and Polytip jacks—both outputs and CV control inputs. CV is mappable to parameters, and the entire setup can be saved as a “preset.” This module brings polyphonic modulation into our new world of polyphonic patching.

Multipass – Eight-Voice Multimode Filter

Please welcome the second filter in our polyphonic series: the Multipass. This one carefully recreates the rare OB-X filter design (not the later CEM-based OB-Xa), delivering the sound of the ’80s and early techno.

It features extended signal levels on inputs and outputs for an even broader tone range. LP, BP, and HP modes are poly-voltage controlled and simultaneously available per voice through Polytip, and via a mixed output jack. Each filter mode has manual gain control via dedicated faders. Frequency control is polyphonic and can be over-modulated by a mono signal with adjustable scaling. With all its poly mod inputs, this filter goes far beyond its classic roots.

Where and how much?

The first batch is ready, and we expect to begin shipping to shops soon. Price will be in the $500–$600 range.

Resonator

An extended design based on the analog resonator from the 1975 Polymoog synthesizer. This classic beauty works with everything from drums to polyphonic audio, adding lush resonating swirls.

There are three resonators, each with a selectable band. Each has voltage control for every parameter, nine CV inputs in total. Multiple gain stages (master input, resonator gain, and mix output) allow fine control and help manage clipping. Emphasis CV range boundaries prevent runaway self-oscillation. A true-bypass switch makes it easy to compare processed and dry signals—perfect for leaving it patched in and engaging only when needed.
