How Notes Are Computed in the Encoding Scheme

This application uses a binary-based encoding system to determine which notes are played from numerical values. Here's how it works:

1. Binary Representation of Numbers:

   • Each number is converted into binary, with bit 0 at position 0, bit 1 at position 1, and so on. For example:
     • The number 5 becomes 1010.
     • The number 10 becomes 0101.

2. Pitch Class Assignment:

   • Each binary digit corresponds to a position in the selected pitch class set going up octavewise to the maximal midi pitch. For example, for 7-35.11:
     • Position 0 = C
     • Position 1 = D
     • Position 2 = E
     • Position 3 = F
     • Position 4 = G
     • Position 5 = A
     • Position 6 = B
     • Position 7 = C
     • ...

3. Chords:

   • If multiple 1s are present, the corresponding notes form a chord.
     • Example: The number 7 (111) maps to C, D, and E.

Summary

To compute notes:

• Convert the number to binary (bit 0 = position 0).
• Map 1s to their pitch classes.
• Apply an octave offset for final pitches.
• Combine active notes into a chord.
