What does the Drum Farm actually do?
The Knobula Drum Farm is one 24HP module trying to do the job of three. It is a drum synthesizer, a sampler and an effects unit at once, and Knobula built it without a screen. Every function sits under its own knob, and every parameter can be patched to a CV or trigger input.
The synthesis side runs 16 drum models, a mix of virtual-analog algorithms, physically-modelled drum membranes and shells, and spectral cymbal synthesis. That covers the obvious Roland reference points, the TR-808 and TR-909 kicks, snares and hats that built house and techno, alongside metallic and tuned percussion you would normally reach for a separate module to get. On top of that sit 16 real-time effects, up to three at a time, including reverb, delay, bit crushing and distortion, plus a couple of Knobula's own ideas like Pitch Dive and Octave Warp.
The sampler is the clever part. It records continuously in the background into 16 sequential buffers, so the last sixteen things that passed through the module are always sitting in memory. Knobula's own pitch for it is blunt:
Think of it as an undo queue. Never lose those happy accidents again.
Two independent players fire those samples back with their own trigger inputs, and a microSD slot stores 32 banks of full sessions.
Why cram everything into 24HP?
Eurorack is a space-and-money game. A serious drum setup usually means a kick module, a snare or clap, a hat or cymbal voice, then a separate sampler and an effects send, and every one of those eats both HP and budget. The Drum Farm answers that by folding the whole rhythm section into 24HP for 449 pounds, which is why it became the most-previewed drum voice at Superbooth 2026. Reviewers who paired it with a second percussion module, like the Ohmforce Bohm, came away with a complete, performance-ready techno rig in a tiny slice of a case.
Is it built for techno?
Yes, and the layout shows it. Five trigger inputs, four CV inputs, a main and an aux output, plus a USER and ROM switch and that microSD slot, all aimed at a producer sequencing live rather than clicking through pages. The 808 and 909 DNA is right there in the models, and the constant sampler turns any sound on your bus into raw material in seconds. This is a module built to be played, not programmed.
