pattern editor {
    iosevka works perfectly for tracker patterns
    C-4 01 vFF
    can freely embed it too (SIL OFL allows bundling)
    probably Iosevka Term (Light?)
}

project data {
    samples are held in memory as {
        QString name, QUuid id (used as dictionary key) (?)
        sample rate, channel count (1 or 2), length
        probably QSharedPointer to raw float array (size=length*channels, non-interleaved)
    }
    
    pattern {
        name, id
        length in rows (duh)
        time signature, in beats per measure and rows per beat (can default to project global)
        
        per-pattern channels; note continuity is defined by name
        - send note-off on entering a pattern without a channel of that name? maybe project setting
        
        command format
        01 C-5 v7F ... ... ...
        instrument (port) number first; note-sharp-octave notation same as most trackers, but arbitrary number of a single type of parameter
        [plugins receive commands more or less exactly as written; meaning is by convention more than anything, but there is a "standard" way of handling notes, handled by a library on the lua side]
        - leave pitch bends to automation? or build them as per-tick messages from host? also, stepped by tick or smoothed per sample?
        x note-on events send the actual note as a float value
        - nope, separate event for cents (bcd? that would futz with interpolation though... signed byte, -100..100)
    }
}

resampler object {
    one used internally for each note
    reference to sample
    wrap mode (flat, loop, pingpong)
    double position (number of samples with fractional part)
}

lv2 support: lilv (duh) for actual plugin loading, suil for UI embedding

keybinds {
    pattern editor {
        note column {
            ( a-z, []\ ;' ,./ ) - "flat piano" in three octaves a la openMPT (maybe minus /)
            shift - hold to transpose up one or two octaves while playing
            1234567890 - assign octave
            note off, hard cut?
        }
        param column {
            symbol {
                anything printable - set symbol and move to value
            }
            value {
                minus - negate current value
            }
        }
    }
