-Quick start (6 minutes):+===== Concepts ===== 
 + 
 +==== Workflow and sequencer ==== 
 +Drambo is a virtual modular synthesis and sequencing studio that consists of modular synthesis tracks, each with a corresponding sequencer track. The synthesis tracks can be chosen by hitting the corresponding drum pads. 
 +An audio mixer channel representation of all tracks that also allows for scrolling through tracks can be shown by hitting the upper right "burger menu" symbol, while a grid representation of all sequencer tracks can be shown by hitting the upper right dot grid symbol. As Drambo supports both landscape and portrait orientations of your iDevice, more sequencer or modular synthesis tracks can be seen by turning the device into portrait mode. 
 +It can be a good idea to place tracks next to each other that may require simultaneous tweaking, especially when using AUv3 plugins that rely on visuals. 
 + 
 +Drambo's sequencer is built around a pattern concept. Each pattern has a certain number of steps and repeats and unless the "Loop" symbol on the transport bar is enabled, all patterns will play in a linear sequence. After the last pattern has finished playing, Drambo will continue playing the first pattern again. 
 + 
 +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. 
 +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. 
 + 
 +==== Routing ==== 
 +Drambo allows you to connect modules without wires. Tapping on a signal port which is not yet connected will show all ports that can it can be connected to, which are all modules that are located before the module you're about to connect. When designing modular creations, keep this limitation in mind, as it may in some cases (instant Feedback) require a few duplicate modules to achieve the same effect as in classic modular systems. 
 +Connections are indicated in two ways: The color of a signal port is the same as the module it receives from, and when you tap on a signal port, both the port and the connected port will flash in orange color.   
 +Double-tapping on a signal port will open a popup menu to disconnect that port. 
 + 
 +Routing is not limited to a track. You can also route signals between tracks, including track mixer modules in the "Main" channel. When routing MIDI signals, be aware that routing MIDI to a track will make the MIDI signal available to track modules, not to the sequencer. 
 + 
 +==== Signals ==== 
 +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. 
 +As of December 2020, Drambo works with the following signal types: 
 +=== 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. 
 +=== MIDI === 
 +A stream of MIDI messages. It's a unique signal that can only be used with modules that have MIDI ports. There's a number of modules available though to convert between MIDI and control signals. 
 +=== 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.) 
 +=== Modifying signals === 
 +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, a time signal groove quantizer feeding Gate/Velocity and CV sequencers or a 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. 
 + 
 +==== Real-time parameter control ==== 
 +Drambo offers multiple methods to manually and automatically change one or multiple parameters, knobs and buttons. They all have the same type of destination, the parameter(s) under control but they have different sources. These sources are available: 
 +=== Parameter locks (p-locks): === 
 +These are tied to sequencer steps. Each step can store one or more value changes. Changes to parameters remain active until the next non-empty step in the sequence of the same track. Note that these are the only way to store parameter changes inside a sequencer pattern. 
 +=== Modulators: === 
 +A wide choice of modulation sources is available. You can use LFOs, oscillators, envelopes, graphic modulators, or even the Flexi sampler which could be used to record an automation signal and play it back either whenever triggered, or in a loop and in sync with the pattern playback. 
 +=== Scenes: === 
 +Independent from patterns and track modulators, scenes can store parameter changes as "presets" or "snapshots", so to say. Up to 16 different snapshots can be stored and recalled on scene pads A to P, and choosing a scene is done by hitting either the left or right button next to the horizontal crossfader which will allow for seamless morphing between the snapshots stored on the scenes chosen on the buttons left and right from the crossfader. Like modulators, these are independent from the pattern sequences and will work globally. 
 + 
 +==== Creating Sampler instruments ==== 
 +Since february 2021, the Sampler can automatically import and map samples to appropriate key and up to 4 velocity ranges. 
 + 
 +For this to work, your samples need to follow one of these file name conventions: 
 +**{SampleName}_{NoteNameOr3digitNoteNumber}_{3digitVelocity}.fileextension** 
 + 
 +**{NoteName}{space  or _ }{optional: letter v}{3 digits velocity}** 
 + 
 +**{NoteNumber}{space or _ }{optional: letter v}{3 digits velocity}** 
 + 
 +Upper or lower case shouldn't matter but make sure file names don't have more than two spaces or underlines, they separate file name from note numbers and velocity values. 
 + 
 +Supported formats are M4A/AAC, MP3, WAV, AIF, any bit depth and any sample rate and 1 or 2 channels. 
 +Flexible sample rate support also allows you to adapt each sample's sample rate in order to save space, something that had often been done in 80s and 90s hardware samplers to get the most out of very limited RAM in these machines. 
 + 
 +Sampler will try to map samples according to note name (also setting the root key from the given note name/number) and velocity between 001 and 127 for up to 4 samples stacked and velocity switched. 
 +Vertical and horizontal gaps are filled automatically by stretching the mapped range to the next neighbor in a hopefully sensible way. 
 + 
 +Levels will be uniform across different velocity windows in order to not destroy the velocity response in a typical setup where you would follow the Sampler with an ADSR that already adds adjustable polyphonic velocity response. 
 + 
 +Since auto mapping completely relies on sample names, you won't need any SFZ or EXS files for import, just the correct sample names. 
 +Batch renaming files can be done on MacOS using Finder rename or on Windows using the Multi Rename tool in Ghisler Total Commander. 
 +You drop all files into one folder, upload them to Drambo and in Sampler, use the "Create zones from folder" > "Select current folder" function.
