Their S6000 can do the same. Anyone has really understood what
the patent claims? I'm starting to really wonder what is going on.
As I have understood, we are allowed to implement an "instant play"
one-shot/looping sampler based on multitrack editor technology
(envelope/parameter curves) with note on/off. We are allowed to keep
the beginnings of audio segments in memory for instant play. But
I don't know about pitch bend or other advanced sampler properties.
I have tracked down hard disk based systems: for example,
www.dar.co.uk has a long history (at least down to 1988).
I'm still continuing this check but I could put material
available if anyone else is interested in to help me;
it would make a historical intro to hard disk recording
if nothing else. My plan is to go through early magazines of
such as Keyboard and EQ for reviews of hard disk based systems.
I really would like to know how Steinberg and Akai circumvents
the patent, if they do it at all. It would save our time
in knowing what is good enough prior art --- as far as I know
Steinberg had no disk sampler system prior 1997. So, they should
pay license if the patent claims rights to the disk sampler idea.
(However, I have a brochure of a hard disk based system which can be
used as "a disk based 4 voice sampler" controlled with MIDI note
on/off and cuelist.)
Could somebody check details of old Akai S1000 and S3000? In quick
search in the web I found nothing about playing from hard disk
directly.
Any ideas?
Best regards,
Juhana
