Tubbutec 6equencer Eurorack Sequencer Module (3U)

Tubbutec 6equencer (pronounced sequencer, sixquencer, or whatever you prefer) is a TR-606 inspired step sequencer.

It is available in different Eurorack form factors (1U and 3U) and despite being compact has many powerful features.

6equencer is optimized for live performance and allows quick programming and editing of drum patterns.

Features

Step based drum sequencer with 8 instruments inspired by the TR-606.
Compatible with analogue and midi based systems
16 patterns, chainable in song mode, up to 32 patterns in a song
Forward, backward, ping-pong and random play directions for patterns and songs
Mute instruments live
Probability control of steps
Record steps by tapping or via midi
Clear steps while playing
Pattern length can be set individually (Last Step)
Copy, Paste and Clear patterns in song mode
8 trigger outputs with adjustable trigger length, midi out
Analogue clock or midi clock input with adjustable clock divider
Multiple 6equencers can be chained to achieve longer sequences or more instruments.
Trigger and record via midi in, doubles as midi interface
Trigger midi instruments via midi out
Very compact, yet versatile: 3U * 6HP, or 1U * 24HP Intellijel
For a detailed list and explanation of features, please refer to the user manual (PDF), which is also included with the 6equencer. There are a lot more features than listed here.
Firmware update is possible via midi sysex
User interface

The 6equencer user interface features 16 buttons with LEDs and a FUNC button.
Each LED can be red, blue or purple.
Typically a blue LED will indicate a mode or setting, while a red LED will indicate an active step or parameter.
When both, red and blue LEDs are turned on, the resulting color will be purple. This means both are set (e.g. a step is set and a parameter is selected).

Inputs and Outputs

6equencer has 8 instrument outputs and can be clocked via analogue clock or midi clock.
The clock input doubles as a midi input, the RESET or RUN/STOP input doubles as midi output.
It is possible to trigger analogue drum modules, analogue drum machines or midi based drum machines.
Drum patterns and songs

6equencer has 8 instrument channels and is pattern based. Each pattern can have up to 16 steps and 16 different patterns can be programmed.
Multiple patterns can be chained to a ‘song’. Each song consists of up to 32 patterns, a single pattern can occur multiple times in a song.
You can record a new song while another is playing and start the new song in sync. This allows very flexible and intuitive live performances.

Performance features

Many features exist to ease pattern programming and live performance:

Multiple play directions can be selected including a musically usable random mode. The play direction can be changed for patterns and for songs independently. Changing the direction will not cause 6equencer to lose sync as it remembers the “original” play position.A handy performance tool is the MUTE mode. Here you can activate and deactivate instruments while the sequencer is playing and without modifying the patterns. Furthermore, the Low Tom and High Tom instruments can be used to control the probability of other instruments playing.While the sequencer is running, TAP mode can be used to record steps live. Here the instrument buttons can be used to enter rhythms.
In CLEAR mode, the current steps are cleared as long as CLEAR is pressed.Patterns and tracks can also be copied and pasted, allowing the quick programming of variations.
Link multiple 6equencers

Multiple 6equencer modules can be connected to form patterns with more than 16 steps or used in parallel to effectively get more instrument channels.
Up to 4 6equencers can be connected for a maximum of 64 steps per pattern or 32 instrument channels. The connection is achieved via a ‘LINK’ connector on the back of the module.
