The sounds are typical of
the era : lo-fi and possibly a bit 'flat' but useful nonetheless,
particularly the electronic kit sounds.
Both are provided in Nostalgia in a single program. The
DR220a is mapped out from C1-B1 and the DR220e is mapped out from
C2-B2. The sounds are panned to represent a stereo kit. Unlike the
originals, the sounds here are velocity sensitive.
Neither are anything to get too excited about in this
day and age but they do have some vintage character and who knows,
they may find a place in your work.
