Milestones

[zeffii]

Some of these may be implemented early and require re-implementation as my understanding of C++/SDL develops.

---

Drawing

• draw pattern, arbitrary from a file.
• correctly destroy textures to avoid memory leak
• keep font alive for duration of main
• add sequencer view

Pattern Editor

• switch pattern next/last for this instrument
• edit pattern (input notes, change octave column, new hex values, remove values, note off, note cut)
• pattern based current octave for new nodes
• implement selection rectangle
• delete content of cell
• function to interpolate between two hex vales.
• function to interpolate between multiple values over the selection.
• display outline of current cell for caret (caret is always smaller than outline of total cell)
• scroll pattern
  • truly link the visual cursor rect position relative to the viewed portion of pattern..
• cut, copy, paste, wipe selection
• add console facility! (major!!!!!)
  • replace values with their average; f.ex avg |
  • amplify values; f.ex amp 0.4 and amp 1.0 0.0 (linear interpolate the ampliciation between 2 values)
  • reverse selection rev |
    Envelope Editor
• handles, lines, active handle
• kb input, with modifiers for speed.
• limits, (handles can't move beyond rect bounds and handle can not move x lower than a handle before it)

Instrument Editor panel

• sliders + kb handlers
• waveform display, updateable via sliders
• wavetable with tone + overtones + noise mix + rotate + smoothing (dynamic..width independant code)
• default parameters for instrument
• add names to sliders

While i'm not finished the pattern editing stuff, that's one area of the whole project that i'm confident I can fully grasp and make an intuitive interface. Therefor it;s time to shift gears and tackle things that i've been putting off.

• adsr / NNA , controlled via keyboard ( i really don't care much for mouse control )
• how to get sound out of this,, (scares me a little..)

[zeffii]

Sound is the endgoal of this thing, and it's time to figure out how to implement that part of it.

• CSOUND lib ?
• SUNVOX lib ?
• STK https://ccrma.stanford.edu/software/stk/papers/stkupdate.pdf ?

[zeffii]

• maybe a Bela / beagle bone unit driven?
• maybe OneLoneCoder 's sound engine ? :)

[zeffii]

The bela tutorials are a good resource for learning about waveform reading / playing. I think i have everything I need now to start exclusively looking at how to get sound out of this thing. Anything else I do now that isn't directly sound related will be merely procastination. I don't want to use JUCE, but might.. or the other libraries above.
