if you pay for postage both ways, i'll read them, send them back, and post the
BINs here. (small files)

I'd love to figure out how to burn my own sounds. I've been having this
discussion with a few people from this forum and others. The machine i want
to do this with is the HR-16. I even emailed mr. HR-16 himself, craig anderton
(he literally wrote the book on the HR-16), to see if he had any insight into this.
He responded to my email within hours, saying he'd forward it to alesis, but
that ended up being a dead end. The service manual offered a bit more
insight, but i'm still not there yet.....

I dont have a 707, but my bandmate does, and i have a 505. I know from CJ
on this forum, that the roland machines are very tricky in this regard:

In addition to sound data on the voice chips, the audio gets processed by
filters and ADSRs. And not all the sounds are the same bitrate. By contrast,
the HR-16s sounds (i THINK) are all the same bitrate, and only get minor
volume processing (i THINK).

So, IN THEORY- you could take a 707 BIN file, open it up as raw data in an
audio editor (but you'd need to know the proper bitrate, etc.), replace some of
that data with your own, save a new BIN, and burn that to a new chip. IN
THEORY. As an experiment, you might want to take a 727 drum sound, and
copy and paste it to replace the coresponding 707 drum sound, and see if
your new chip will have the new sound on it. I haven't tried this yet, but a friend
of mine has, with the HR, and also with the casio sk1. He hasn't had any luck
so far, even just changing little things. The new rom will either not work at all,
or have undesired results. I think it's because he's converting from data to
.wav and back. Maybe the bitrate is slightly off, which would throw everything
off. I'll be doing my own experiments with the HR-16 roms soon.

So, long story short- yes, i can copy the roms. But it might be very tricky to get
your own sounds on them.
