synthio: make most Note constructor args kw-only 
for similar reasons as Envelope. The mandatory frequency argument can
still be given as a positional argument.

rp2040: fix audio glitch at soft-reload 
The internal flash cache wasn't being properly used, because
`write_blocks` unconditionally performed the flash write.

Fixing this so that the write's not done until `internal_flash_flush`
fixes the problem in my test program with i2sout & synthio.

as a future optimization, `flash_read_blocks` could learn to read out
of the cache, but that's probably not super important.

synthio: re-striking a note should re-enter attack 
.. without changing the current note amplitude

synthio: make sustain level relative to attack level 
and re-vamp overall envelope calculation again.

Now, if you set a low overall attack level like 0.2 this avoids the
"diminishing volume" effect when many notes sound at once. You need
simply choose a maximum attack level that is appropriate for the max
number of voices that will actually be played.

synthio: replace the quietest releasing note when over-writing 2023-05-04 07:23:49 -05:00

synthio: slow ramp overall envelope back up 
.. and account releasing notes at their sustain level until they're
done.

this ameliorates the effect where multiple releasing notes
don't seem to actually be releasing, but stay at a constant volume.

synthio: Add synthio.Note 
This class allows much more expressive sound synthesis:
 * tremolo & vibrato
 * arbitrary frequency
 * different evelope & waveform per note
 * all properties dynamically settable from Python code

Add additional iMX RT support 
This adds a script to generate the peripherals files (except clock).

It adds support for the 1015, 1020, 1040, and 1050 EVKs.

Some work was started on 1176 but it isn't working. So, the board
def is in a separate branch.

Fixes #3521. Fixes #2477.
