* ''Harmonic table'' - This is a list of ratios or scales used to emphasize overtones in the string, each ratio corresponds to a MIDI or CV note in an octave. The default harmonic table contains 12 ratios per octave and are derived from just intonation.

* ''Harmonic / Harmonic number'' - a single ratio and octave in the current [[The Ekdahl FAR - Getting started#harmonic table|harmonic table]]. The ratio is used to calculate the bowing frequency from the fundamental, this frequency will emphasize a certain overtone. e.g. a harmonic number 17 in a 12-note scale refers to the 5th ratio on the second octave from the fundamental.

* ''Harmonic shift / fine tune'' - freely shifts the frequency of the [[The Ekdahl FAR - Getting started#bowing wheel|bowing wheel]] from the [[The Ekdahl FAR - Getting started#harmonic number|harmonic number]] set. ~~The [[The Ekdahl FAR - Getting started#command|command]] issued is dependent on~~ the [[The Ekdahl FAR - Commands#harmonic shift range|harmonic shift range]] ~~which can be edited with~~ the [[The Ekdahl FAR - Configuration Utility|configuration utility]].

* ''Harmonic shift / fine tune'' - freely shifts the frequency of the [[The Ekdahl FAR - Getting started#bowing wheel|bowing wheel]] from the [[The Ekdahl FAR - Getting started#harmonic number|harmonic number]] set, this is analogous to a ''pitch bend''. By default, the range of the shift can be changed by editing the [[The Ekdahl FAR - Commands#harmonic shift range|harmonic shift range]] using the [[The Ekdahl FAR - Configuration Utility|configuration utility]].

* ''Control method'' - the method of control used. This can be CV, USB-MIDI, MIDI or USB-Serial as of the writing of this document.

* ''Control method'' - the method of control mechanism used. This can be CV, USB-MIDI, MIDI or USB-Serial as of the writing of this document.

* ''Command'' - the Ekdahl FAR is entirely controlled by ~~internal~~ ''commands'', these decide ~~what~~ the instrument is doing ~~and changes~~ internal ~~parameters~~. When a MIDI event occurs or a new CV / knob value is read, the ''commands'' associated with it will be sent ~~to the instrument~~. This can be things like "engage hammer" or "set the fundamental frequency" etc. Some of the available ''commands'' are mainly used for calibrating and setting up the instrument and are usually saved into the instruments memory, these will be executed whenever the instrument is turned on. All ''commands'' can be manually invoked via USB-Serial.

This can be things like "engage hammer" or "set the fundamental frequency" etc. Some of the available ''commands'' are mainly used for calibrating and setting up the instrument and are usually saved into the instruments memory, these will be executed whenever the instrument is turned on. All ''commands'' can be manually invoked via USB-Serial, in conjunction with certain softwares this presents an unprecedented level of control and sequenceability.

The front panel has all the basic connections required to interface with the Ekdahl FAR.

The 'sounds' jack is the main audio output and the volume is set with the 'sounds' knob, due to the fact that different strings will have a different output levels, the gain offered will make the sound distort if turned up too high at times. Care should be taken to find a good balance in between noise ~~floor~~ and the possibility of ~~the sound distorting~~.

The 'MIDI' jack is a TRS 3.5mm Type A jack as adopted by the MIDI standard.
