The Rhythm Sequencer module focuses on the creation of rhythmical patterns. It provides both gate and velocity control.

Its standard voltage outputs will interface with most regular modules but it is specifically designed to be the primitive beating heart that drives other Adroit modules in the production of melodies, chordal accompaniments, bass lines and drum patterns.

It is especially powerful when combined with the Adroit Groove module which allows you to systematically adjust the velocity and micro-timing of each step in a rhythm – transforming clockwork into something that really feels alive.

Note there is some subtle complexity to this module so in addition to this overview there is a Rhythm Sequencer Operation page that goes into greater detail.

The sequencer has 16 steps when Song Control is set to 4 beats/bar and 12 steps when Song Control is set to 3 beats/bar. So there are always 4 steps per beat, this makes it easy to produce rhythms that work in both 4/4 time and 3/4 time (and their derivatives).

The GATE OUT socket transmits the current gate value in the sequence.

The VEL OUT socket transmits the current velocity value in the sequence.

The VEL OUT signal also controls the gain of a handy built-in voltage controlled amplifier (VCA).

Like all Adroit sequencers the Rhythm Sequencer uses the Adroit V/Bar standard where time is represented by a voltage rather than being dependent on clock signals.

The V/BAR IN socket receives the voltage controlled time signal from the Song Control Sequencer or a Time Splitting module (or some other CV source for more experimental applications).

Use the numbered buttons to program the on/off gate pattern.

Gate Buttons

Individual buttons can be switched on or off with a left mouse click but if you hold down the mouse button and swipe left or right it’s possible to change multiple button states in one swift operation.

Helpful shortcut function buttons at the top can be used to create a convenient starting point…

Gate Shortcuts

RECORD arms recording for gate signals received via the upper REC IN socket.

RESET turns all steps off.

INVERT turns buttons that are off on and vice versa. So one way to quickly turn all steps on is to press RESET then INVERT.

RANDOM sets a random pattern.

X – sets every odd numbered step on.

X – – sets every third step on.

X – – – sets every fourth step on.

X – – – – sets every fifth step on.

The colored bars below the numbered buttons show the velocity for each step.

Velocity Bars

Use the mouse to alter the velocities. You can hold down the left mouse button and quickly “draw” shapes or you can click on individual bars to change just one step.

A right click copies the velocity of the previous step to the step being clicked on. You can also hold down the right mouse button to quickly swipe across a number of steps so that they all end up sharing the same velocity value.

Directly below the colored velocity bars there’s another bank of shortcut function buttons that change the velocities…

Velocity Shortcuts

RECORD arms recording for velocity signals received via the lower REC IN socket.

RESET sets all velocities to the default 75% value.

RANDOM sets the velocities to random values.

RISE sets the velocities in increasing order to create a crescendo effect.

FALL sets the velocities in decreasing order to create a decrescendo effect.

TIDY sets the velocities to reflect the rules that determine the actual velocity output as described in the Rhythm Sequencer Operation section.

The lowest row of buttons affect both gates and velocities and let you perform useful operations on the entire pattern.

Buttons that affect the entire pattern

< SHIFT shifts the pattern one step to the left (earlier in time), rotating the first step to the last.

SHIFT > shifts the pattern one step to the right (later in time), rotating the last step to the first.

The COPY and PASTE buttons allow you to copy data from one Rhythm Sequencer to another – handy for quickly creating subtle variations from bar to bar. Click on COPY to copy the pattern to the clipboard. Click on PASTE to copy a pattern from the clipboard to the current module.

When the TIE button is engaged adjacent steps with gates that are on are merged together to form a sustained note.

Generally when programming drums or very fast melodies one would set TIE off so that sixteenth note rhythms are preserved, but otherwise setting TIE on allows for the natural programming of varying note lengths.

When the TIE button is engaged velocities for tied steps are locked together as one would expect.

When the OVER button is engaged the very last step is tied over to the next bar. This enables notes to span bar boundaries and also allows sustained notes that last for several bars to be programmed.

COLOR enables you to pick a color for the gate buttons and velocity bars. This is handy in a large patch for color coding certain functions. Or perhaps you just have a favorite color.

The GROOVE IN socket takes signals from an Adroit Groove module enabling micro-timing and dynamics adjustments to be made to each step.

The DYNAMICS knob enables you to adjust the effect of the groove on the module’s velocities. At minimum setting the module ignores groove dynamics completely. At the default (12 o’clock) setting groove dynamics have a normal effect. At maximum setting groove dynamics have twice the normal effect on velocities.

The GATE TIME knob sets the duration of the gate. The CV IN socket to the left of the knob enables the gate time to be voltage controlled.

The MX IN and MX OUT sockets enable Mutual eXclusion signals to be passed between Rhythm Sequencers. Use these to set up easy programming of things like open and closed high-hats that should not occur at the same time. Switching on a step on one of the sequencers will automatically switch off that step on the other sequencer.

The LINK OUT socket feeds control signals to a paired Adroit Melody Sequencer so that the Melody Sequencer and Rhythm Sequencer work in tandem.

The REC ARM IN socket enables both RECORD buttons to be engaged by a trigger voltage. Typically from the REC OUT socket of the Song Control module. This allows multiple Adroit sequencers to be armed for recording by the press on a single button.

Sequence lengths can be extended indefinitely using the Song Control Sequencer, Time Splitters and the MERGE sockets to chain any number of Rhythm Sequencers together.
