MITS was prototyping the MU-1 music card with 6 square wave channels (no
envelope/volume/pitch/etc). When Pertec took over they killed the
board. I have a bare PCB version of this prototype and may bring it back
to life...

There was a special version of basic for the card with added note/duration
commands. There was also a version of startrek for the card that ran under
regular basic and had sound effects during the game.
ARP's project would have cost an individual a lot to put together. A bank
of Pro Soloists...

Now that system connected to the 4 channel Bose sound system (on loan) must
have sounded amazing, even by today's standards! : )

I have source code and custom interface cards
from ARP's project to create
the first consumer computer controlled synth. The prototype was built out
of an Altair 8800. Never finished, never released. It was a top secret
project within the company
Many (myself included) simply tied a capacitor to the front panel
interrupt enable LED of the 8800 and fed it to an audio system. It
was quite workable. Later I did an S-100 card with 5 GI sound chips
on it.
