Chord Playback Speed

This enables  chords selected to be played in the form of anything from a slow arpeggio to a chord

Scale playback Speed

This various the tempo from very slow to instantaneously playing all the notes in the scale at once

Sequencer Tempo

This varies the speed of play back of chords or arpeggios when 11-v-1 selected

Note transposition

This primarily for horn players.

• Bb for trumpet, tenor and soprano saxophone, clarinet, etc
• Eb for alto and baritone saxophone, etc
• Low C is self explanatory may also be used in later versions to change to sound and visual display of a bass guitar

This is is the first sample version not only providing an understanding of how the cycle of fifths works but also a practice regime for the all important ability to play arpeggios, chords and modes round the cycle of fifths.

With subsequent version a significant increase in the number of practice regimes is planned. Everyone will want it!
