Work in Progress

ION - Music Studio

SP4CEBAR 2024-01-05 16:21 (Edited)

This fifth iteration of my piano roll music studio has:

• A more light-weight and more efficient GUI engine (the previous engine used over 15000 tokens)
• A mostly consistent GUI
• bigger buttons
• Polyphonic tracks (comes later)
• A screen that shows more details of the last GUI element you pressed (comes later)
• The music will be built upon my music API

Each page has a scroll-and-selector-bar on the top right to select anything that the word on the top left says

You can select tracks on the project page, each track will have one or more sub-tracks, a sub-track can be a piano track or a drums track, you can select your sub-track with the scroll-and-selector-bar on the top right of the piano and drums pages.

• A piano sub-track will have a fixed instrument, this instrument can be set with the scroll-and-selector-bar on the top right of the synth page. Each piano track has a piano roll (a matrix of pitch and time) and a volume knob to set the volumes of your notes.
• A drums track will have matrix with a bunch of drum sound presets and the time, you can use the pitch and instrument knobs to set the pitch and instrument of each preset.

If a time slot has more notes in it than your track allows, it will change color to indicate the issue.

The effect automation system is similar to the sub-track system: you can select your effect on the top left, and a time slot that has too many effects in it will change color.

The project page allows you to select your tracks and write them to your patterns, on this page you can also select the ROM entry to save and load from.

I just found the following function within the source code of this program: this is the secret behind the lightweight touch system

• C1X1 means a 1X1 cell, C2X2 means a 2X2 cell, etc.
• ROOT_CELL is a bitmask to disable some bits in the character code to arrive at the root cell, which is the upper left character code of a 2x2 or 2x1 cell (I'm impressed now, even though I wrote it)
• The USER_GUI function then compares all its variables to see if it is equal to one of the predefined root cell variables (there's one predefined root cell variable for each button to make the code nice and readable)

SUB TOUCH_REDIRECTOR
  IF TAP THEN
    X= TOUCH.X\8
    Y= TOUCH.Y\8
    C= CELL.C(X,Y)
    ROOT_CELL_2X2 = %11101110
    ROOT_CELL_2X1 = %11111110
    C2X2= C AND ROOT_CELL_2X2
    C2X1= C AND ROOT_CELL_2X1
    C1X1= C
    IF C<>0 THEN CALL USER_GUI( X,Y,C1X1,C2X2,C2X1 )
  END IF
END SUB
