The Eigenlabs software is based on a modular synthesis model which allows control inputs to be routed and manipulated by an advanced user to achieve a wide variety of effects. Almost any control from the keyboard or MIDI inputs can be used to manipulate any parameter in the system. Many of these options are available to users via the Eigenlabs Browser, the Stage application and the keys on the instruments. More advanced configuration is possible via the Eigenlabs Workbench which is available as part of EigenDPro. EigenDPro is not supplied with our instruments as standard but can be purchased separately in our online store.

• Soundfont oscillator (SF2 files, other sampler formats such as ESX24 can be used via CDXtract) with ability to cross fade between two sample sets on key yaw.
• AHDSR envelope generator (with complex functions for key press shaping).
• Drummer (plays AIFF loop files with tempo time stretching).
• Sine/Sawtooth/Square oscillator.
• Filter – High/Low/Bandpass.
• Ladder Filter.
• Gain control.
• Mixer with effects sends/returns and stereo panning.
• Cello physical model (can be bowed via strip controllers, breath pipe or a key).
• Clarinet physical model.
• AU Host.
• Hardware MIDI Output interface.
• Hardware MIDI Input interface.
• Convolution engine.
• Multitap, multiline delay.
• Value range changer.
• Keyboard splitting, routing, and course definition.
• Recording and playback of takes.
• Musical Scales and pitch bending.
• Metronome for musical clock generation (including a tap tempo function to set tempo from a key).
• String model to impose string-like or wind instrument type monophony.
• Grouping of modules into defined software instruments.

Scales can be defined in an instrument, or can be associated with a key routing so that the scale, octave and tonic change according to how the instrument is being played.

• Built in scales: 86.
• Scales can be added by request, in floating point values if you wish (so microtonal scales are possible), please send us your idea.

The system allows defined events to take place according to a variety of triggering actions. Events that can be triggered include:

• Global and individual instrument mixer channel volume changes.
• Parameter and configuration changes.
• Various actions in the graphical interface.
• Starting and Stopping of the metronomes.
• Playback of recorded takes.
• Initiation of a new recording.
• Starting and stopping drum loops.
• Playback of a single note.
• Changing key.
• Changing scale.
• Changing tempo.

These actions can be triggered by various modules, which currently include:

• Talkers – triggering an action mapped to a specific keypress.
• Scheduler – triggering actions at times within a song.
• Arranger – triggering according to a repeated pattern (ie. step sequencing).

Talker actions can also be triggered by MIDI input notes from external MIDI hardware, so midi foot boards can be used, for example, to change key or tonic, or tempo, while playing.
