Refactor Internals about react-music HOT 4 CLOSED

To further expand upon this, I thought about this more as a developer and less as a musician. I think a couple of things need to happen.

Make steps on sequencer

We should be able to do something like this:

<Sequencer
  steps=[
    [0, 127, "c1"]
  ]
>
  <Instrument/>
</Sequencer>

And further:

<Sequencer
  steps=[
    [0, 127, "c1"]
  ]
>
  <MIDIOut channel={8}/>
</Sequencer>

Make instruments

So single oscillator synth tags are basically worthless unless you're making chiptune or something. We need to compose them into patches. Something like:

<Instrument >
  <Synth type="sine"/>
  <Synth type="sawtooth"/>
</Instrument>

Further, this lib shouldn't always loop. There should be a way to design a patch via MIDI in. Imagine this:

<Instrument midiInputChannel={2} >
  <Synth type="sine"/>
  <Synth type="sawtooth"/>
</Instrument>

Where you could play your patches with an external keyboard and have the sound design hot reload!

Arrangement

Arrangements could be top level tags, sequencers for sequencers if you will. Sequencers that are nested would not loop, but instead use a repeat prop to build arrangement bars:

<Arrangement repeat={2} >
  <Sequencer repeat={1} bars={4}/>
  <Sequencer repeat={4} bars={1}/>
</Arrangement>

These could be used to compose full length songs! Or at least longer loops with variety.

Let me know if I'm crazy

@kenwheeler Somewhat related question - do you think a refactoring could enable easier state changes, specifically to support re-rendering with changed child props?

My use case is that I have a button outside the react-music world that influences how the sequencers behave (by modifying steps appropriately when state changes).

Right now the props are only read on the initial mount, but not on consecutive rendering runs. Ideally it would keep playing at the same point in time after a state change, but a clean reset would also work.

Glad to see that MIDI is not forgotten. My Roland 808 talks via channel 16 with cubase via a converter. When you have anything MIDI I'll be glad to try it.
