Melodies are generated from the random selection of notes which belong to a given scale and key. For this purpose, the App uses music theory and probability.
Yes. Given the random nature of selecting the notes of the melody, it is possible that a generated melody could be repeated. However, the probability that this happens is too low.
Yes. Version 4.0 of the App added this feature. You can now add a voice recording into a generated or created melody through microphone.
No. The purpose of the App is to generate a sequence of notes (a Melody) in a random way in order to help composers, musicians or amateurs in the creation of original melodies for their compositions. Melodies are independent from the instrument, background, lyrics or rhythm which they are played with.
The choice of using the melodies for singing, solo or first plane of a song is up to the user and it is usual that a song or composition is composed by several melodies.
In the app, rhythms and voice recordings are features that enhace perception of created melodies, but they are not tied to the melody itself. Depends on the users whether to use those rhythms or recordings on their final compositions or songs.
Yes. The app has three different ways to export/share melodies
In music, BPM is an Acronym for Beats Per Minute. It means, how many beats in some song appear in a minute, and it describes the tempo of the song.

This button, creates a similar melody to the currently played melody (or created melody) by changing only a few notes. This function was added, because it is usual that a song or music composition use the same melody several times with small changes.
Melody notes are chosen randomly from a scale of three octaves. Melodic complexity defines how high or low one note might be selected respect to other.
A high melodic complexity means that from a given note and scale, the next chosen note could be any of the notes of a full span of two octaves (for example you could have a A1 after C-1 note). This could result in abrupt changes on the melody. In contrast a medium and low melodic complexity narrow the span of notes relative to the note to enforce a more melodic combination of notes.
It is the quantity of notes of the melody in relation to silences. A high rythmic complexity may have notes in all positions given the length of the melody, while in low and medium complexity this quantity is reduced resulting on more regular spaces between notes.
Melodies and rhythms in the app are translated into MIDI format using General MIDI Standard Level 2 (MIDI GM2). This standard supports most of the instruments available in the app yeilding into a very similar melody playback. However, in regard to Rhythms, this standard only have one percussion channel with limited access to instruments that generate rhythm, specially for latin rhythms.
Based on this, when the App does not find an equivalent instrument to translate Rhythm, it maps that instrument into other key that is available. In order to listen for the exact same rhythm in the App, user must map the correct instruments in the MIDI. The following diagram shows the key mappings for the percussion channel that the App uses to make the conversion.
