High Powered Mobile bass unit

Listen to those bass sounds!

Found this used accordion last week.
This is an Excelsior Digisyzer from the 80s (I guess), an hybrid acoustic-electronic instrument. It originally came with a tone generator but I don’t have it. So the sound heard is only the acoustic unprocessed accordion, but what a sound!

Speech samples from my Memory Collection 02 sample pack, sounds from Public Domain documentaries.

I am very new to accordions and I’ve read that the growl heard when I release a button or a key is normal. Seems like it’s the reeds of the lowest notes that keep vibrating. But the instrument may need a check-up. In any case, I like what it does here.

Curiously, I am not finding much info about this on the web.
