[sdiy] Roland PB-300 kick: is it an 808?

[Adam (synthDIY)]

Interesting!
Good basic analogue sounds - ripe for tweaking. 

Is there no clap? Most complex voice circuit of this era.

I wonder what the controls marked “Hold, Arpeggio,etc” are doing on a rhythm machine?

And don’t knock the DR-55!! There is no muddy live PA ever existed that could muffle that rim shot!!
