| The sequencer has a modular concept, much like the synthesis modules but with features specific to sequencing. Sequencer step modules are called "Step Components" and they can be shown by hitting the STEP button on the right. Apart from the most common "Note" component, many other step components are available that perform certain actions or define conditions under which the following step component is executed. This is one way to play, for example, a sequenced note only every 4th pattern repeat or randomly at this position. | The sequencer has a modular concept, much like the synthesis modules but with features specific to sequencing.

| Polymetric sequences with different sequencer lengths on different tracks can be achieved by adding a "Jump" step component on any sequencer step. It allows for jumping to any other step in the sequence as soon as the playhead in this sequence reaches that step. | Polymetric sequences with different sequencer lengths on different tracks can be achieved by adding a "Jump" step component on any sequencer step.

| | In addition to the main sequencer tracks, there are sequencer modules that work like classic modular CV/Gate sequencers. The most important one would likely be the Misc => Gate+Velocity Sequencer module which can also used for controlling oscillator pitch. |

| There are different types of signals inside Drambo. Some of them are unique, others are interchangeable and only have different labels to facilitate a straightforward workflow. | There are different types of signals inside Drambo.

| === Audio, Pitch, Gate, Velocity, Time: === | === Audio, Pitch, Gate, Velocity, Time === |
| These all behave like "analog signals" like you find them in hardware modular systems. Check Drambo's built-in manual (page 6) for details. These signals are interchangeable, you might need math modules to adjust their levels to work together as intended though. | These all behave like "analog signals" like you find them in hardware modular systems.

| A stream of MIDI messages. It's a unique signal that can only be used with modules that have MIDI ports.

| === Spectrum/Wavetable: === | === Spectrum/Wavetable === |
| Another unique signal that can only be used inside a Wavetable Oscillator rack, currently only suported by the "Wave effect" and "Wave filter" modules. (Tip: Here is where you can have low, high and band pass filters with arbitrary steepness by combining Wave filter modules and using your sampled waveforms processed to 2048 samples length.) | Another unique signal that can only be used inside a Wavetable Oscillator rack, currently only suported by the "Wave effect" and "Wave filter" modules.

| Most signals (except "MIDI" and "Spectrum/Wavetable") can be processed by a multitude of general processing, math, mixer and utility modules. One very handy module is the Graphic Shaper which allows for drawing arbitrary curves that map a unipolar or bipolar signal to an output signal. This could be a simple velocity re-mapper or value scaler to optimize MIDI control of certain parameters, but since it runs at full audio rate, it can also be used for wave shaping and more exotic sound design. By feeding it with a simple sawtooth oscillator which has Anti-aliasing turned off, you can draw any oscillator waveform. | Most signals (except "MIDI" and "Spectrum/Wavetable") can be processed by a multitude of general processing, math, mixer and utility modules.
