The Division Department - 01/IV

The 01/IV is a powerful drum synthesizer with four voices. Each channel is equipped with two analog and two digital sound sources, a multi-mode filter, a VCA and three modulators. In addition to standard drums such as kicks, snares, toms, hi-hats or cymbals, it is also possible to create experimental percussion elements thanks to flexible FM routing. On top of that, the 01/IV can be used as a drone synthesizer.

The 01/IV is composed of four identical drum voices, which can be played manually or via MIDI. The synthesis channels follow the classic subtractive VCO-VCF-VCA structure and offer the following core features:

• The VCO section makes it possible to choose from analog waveforms (triangle / sawtooth), digital noise and a hi-hat mode
• Multimode filter, usable as a low-pass, band-pass or high-pass
• Two envelopes for VCA and bi-directional pitch modulations
• The filter can be modulated by either of the envelopes or via the VCO section
• LFO with S&H and one-shot functionality. Its frequency can range from 0.03 Hz to 2 kHz.
• FM routing for combining several voices

Using MIDI CC commands, it is possible to alter parameters not available on the hardware itself. Two examples are the shape of the LFO waveform and the pitch of the hi-hat oscillator.

There is a mix out as well as individual outputs.
