ReaStream format:

UDP port 58710


all ints are little endian

audio blocks:
4 bytes: 'M', 'R', 'S', 'R'
4 bytes: int packetsize: 4+4+32+1+4+2+sblocklen
32 bytes: identifier string (zero padded, last byte always 0)
1 byte: char nch [1-64]
4 bytes: int samplerate
2 bytes: short sblocklen -- largest supported is 1200 (larger blocks are separated)
sblocklen bytes: sample data (32 bit floats, non-interleaved)


midi blocks:
4 bytes: 'm', 'R', 'S', 'R'
4 bytes: int packetsize: 4+4+32+eventlistsize
32 bytes: identifier string (zero padded, last byte always 0)
packetsize-4-4-32 bytes: events
  each event:
     4 bytes: int type (1 = MIDI, ignore message otherwise)
     4 bytes: int bytesize (includes type and bytesize)
     4 bytes: int sample frames since last event
     4 bytes: int flags (see vst spec)
     4 bytes: int noteLength (see vst spec)
     4 bytes: int noteOffset (see vst spec)
     3 bytes: MIDI data
     1 byte: zero reserved
     1 byte: detune
     1 bytes: noteOffVelocity

NOTE: sysex is not currently supported (but we will add it at some point)
