iPad User Guide
Callus Logic for iPad is the guitar simulator app that allows you to:
- Play any note or chord on the guitar's fretboard.
- Easily load chords, scales, and arpeggios in any key.
- View one list of all basic "beginner" chords and see common fingerings.
- Instantly view common fingerings for any chord.
- Instantly view the interval above the root for any chord or scale.
- Instantly see what fret number any note is found on.
- Instantly use one of two different number systems to more easily analyze and understand the music theory behind specific chords and scales.
- Create collections of fretboards to save all the scales and chords used in a particular song or exercise.
- Play a song in any Music app, then open Callus Logic Mobile and play along to that song. This is great for figuring out what key a song is in.
To Get Started:
- Select Scales, Chords, or Basic Chords from the segmented controller.
- Use the Root and Accidental scrollers to select a root note for the chord or scale.
For example: For E, select the note "E" and the accidental "Natural".
**Note: if loading a Basic Chord, the root and accidental scrollers are unavailable, continue to the next step.
- Tap on the Scale/Chord selection button to reveal a popover menu of available scales or chords.
**Note: Arpeggios are selectable from the Scales popover menu (towards the bottom).
**Note: for basic chords, the root note is listed in the Scale/Chord selection button and popover menu.
- To switch between note labels, tap on the Display Mode Scroller, and select:
- Fret Numbers
- Chord Fingers
- Numbers 0-11
- Numbers 0-39
- "Chord Fingers" is only available when either Chords or Basic Chords are selected.
- I = Index finger
- M = Middle finger
- R = Ring finger
- P = Pinky finger
- O = Play the open string
- "Numbers 0-11" replaces note names with numbers:
- E = 0
- F = 1
- F# = 2
- G = 3
- D# = 11
- "Numbers 0-39" assigns a number to each distinct pitch on the guitar:
- The lowest pitched "E" note is 0 (in standard tuning).
- The E one octave up is 12. For example on the 12th fret of the low E string.
- The E two octaves up is 24. For example on the open high E string.
- In standard tuning, the highest pitch on a 15 fret guitar is 39.
- This number system allows you to quickly find Notes that are the same pitch on different strings.
- It also makes it easy to calculate the distance (in half steps) between 2 notes on the guitar.
