- I'm looking for information on two esoteric Commodore hardware
- products for the C64/C128. I say esoteric, since they were never
- marketed in North America as far as I know. I'm hoping that some of
- the readers of this group outside North America might be of
- assistance.
-
- I have three SFX FM Sound Expanders, and one SFX Sound Sampler. The
- FM Sound Expander uses the same VLSI FM digital synthesis chip the
- Yamaha DX7 synthesizer (OPL-II). Supplied with the module is a
- keyboard and some awkward software for composing music and generating
- patches. The Sound Sampler does exactly what it says - samples sounds
- input with either a microphone or line audio signal. It can add echo
- or pitch shift effects. The software provided with the Sound Sampler
- is not much better than bad. It produces clicking and popping noise
- at all times when the sampler is not engaged in a function
- (record/playback, echo, etc.).
-
- What I'm wondering: are there any user groups for SFX hardware? Has
- anyone produced any software for driving these boxes other than the
- original mediocre software that I already have? If so, where is it
- available? The spec sheet for the Yamaha FM chip in the Sound
- Expander says that it supports speech synthesis. Has anyone produced
- any results in this area? Has anyone archived original music
- compositions, sound patches, samples, etc? (I'd especially like to
- change the tuning tables to handle more than 12 tones/octave.) If so,
- where can I find them?
-
- I have a patch librarian for the Sound Expander that I wrote a few
- years ago. It is used to extract and insert individual patches into
- sound bank files. It has a nice user interface with pull down menus,
- screen dump to printer, etc. I also have a large collection of
- original patches and music. If there's interest, I can make it
- available to ftp sites.
-
- With all the talk of making add-ons for video, RS-232, and whatnot,
- and all the interest in adding SID chips for more voices, perhaps the
- SFX deserves a second look. It is much more capable than the SID, and
- interfacing details have already been worked out.
