Those who want to build a hybrid setup combining MIDI/USB with Eurorack

The BEHRINGER 1601 SEQUENCER is a CV-centric analog sequencer based on the classic 1970s 1601 sequencer. It can be used as a 16-step sequencer or operated as two separate 8-step patterns. Equipped with three Gate Buses, pitch-quantized CV, a highly flexible CV range, and clock modulation, it handles a wide range of applications, from melody creation to experimental modulation.

A full-featured sequencer that lets you control pitch, gate, and timing right at your fingertips

1. Switchable between 16-step and dual 8-step modes

In addition to functioning as a single 16-step sequencer, it can be operated as two separate 8-step sequencers. From long melody patterns to patches combining multiple short sequences, you can flexibly adapt its use to suit your system.

2. Build complex rhythms with 3 Gate Buses

Each step features a switch for assigning it to one of three Gate Buses. This allows you to generate different gate patterns from a single sequence, enabling you to trigger multiple envelopes, percussion elements, modules, and more individually.

3. Switch Between 2-Octave Quantization and 10-Octave CV Range

For melody creation, it features a 2-octave quantized pitch range that makes it easy to match pitch. On the other hand, you can also utilize a highly flexible CV range equivalent to 10 octaves, which is ideal for modulation that significantly alters non-pitch parameters such as filter cutoff and PWM.

4. Change Sequences in Real Time with Skip and Reset

Equipped with Skip and Reset functions, you can change how steps progress and adjust the sequence length while performing. Since both functions support CV input, you can even alter the pattern structure itself using external modules. This makes it ideal for performances where you evolve the same pattern in real time during a live set.

5. Comprehensive Control Environment from Clock to MIDI/USB

It features Clock FM and Clock Pulse Width, each of which supports external control via CV. You can vary not only the tempo but also the gate width, allowing you to adjust the expression of the sequence from staccato to legato. Furthermore, it features MIDI and USB connectivity, supporting MIDI channels and transport synchronization.

Applications and Use Cases

Melody and Rhythm Sequencing for Modular Synths
By combining quantized pitch CV with three Gate Buses, you can trigger multiple envelopes and percussion sounds individually while varying the pitch of the VCOs. This allows you to generate both melody and rhythm from a single unit.

Modulation Sequencer for Filters and PWM
By utilizing the wide CV range—equivalent to 10 octaves—you can vary not only pitch but also parameters such as VCF cutoff and PWM on a per-step basis. It also serves as a versatile modulation hub, allowing you to quantize external CV by routing it to the Quantize Input or control Clock FM via CV.

?? Frequently Asked Questions (FAQ)

Q: How many steps does the BEHRINGER 1601 SEQUENCER have?

A: It can be used as a single 16-step sequence or two 8-step sequences.

Q: Can it be used for CV control other than melody?

A: Yes. In addition to a 2-octave quantization range for pitch, it features a free CV range equivalent to 10 octaves, allowing it to be used for step modulation of various parameters such as filter cutoff and PWM.

Q: Does it support MIDI and USB?

A: Yes. It supports MIDI and USB, allowing you to configure MIDI channels and use MIDI transport controls. Additionally, the main module is designed to be mounted in a standard Eurorack case.
