The MachineRoom 204D Dual VCF is a full analogue dual voltage controlled low-pass filter that's perfect for use in your Eurorack modular synthesizer setup. Based on the "transistor ladder" design of the Minimoog 204D, this filter filters out the higher parts of the sound spectrum and allows lower frequencies to pass through, with a cut-off slope of -24 dB/octave like various Moog synthesizers.

With separate controls for both sections, the MachineRoom 204D Dual VCF can be used for stereo operations as well. And with resonance (or emphasis) adjustable all the way up to self-oscillation, the filter can even behave like a sine wave oscillator with V/Oct tracking up to 4 octaves.

The Eurorack version of the Moog Prodigy VCO features a saw core and improved thermostability, allowing for stable and reliable performance. It offers 7 octaves of v/oct tracking and has saw, square, and triangle waveform outputs for both oscillators in a range of registers.

In addition to these features, the Eurorack Prodigy VCO has a LFO mode for OSC 2, hard sync switch, linear FM, slew on the 1v/oct input, and cross-modulation capabilities. It is a limited edition, skiff-friendly module that is hand-built in Kyiv, Ukraine.

Whether you're a fan of the classic Moog Prodigy or just want a versatile and high-quality VCO for your modular setup, this module is a great choice.

The TRILOBITE is a triple saw-core oscillator module inspired by the original Moog schematics. It is made using only thru-hole components and offers a range of features for creating complex and rich sounds.

The module has four octave ranges, three waveforms (triangle, square, saw), and a UNISON (FINE) control with a range of +/- 12 semi-tones. It also has independent LIN FM and PWM inputs with attenuators, as well as a white noise source. Each oscillator has its own audio output, and there is also a mixed output with a level control.

We recommend using the independent audio outputs to avoid distortion. In this case, the mixed output can be used as a white noise source with an attenuator. The V/oct input of the first oscillator is normalled to all three oscillators, but connecting other signals to the other V/oct inputs makes each input independent.

The minimum frequency of each oscillator is as low as 3Hz, making it possible to use them as LFOs. Each oscillator tracks up to 9 octaves.

Please note that the TRILOBITE is a full analog module, so it should be given 5-7 minutes to warm up before use.
