| 1129.1 | Parallel intervals get boring | DFLAT::DICKSON | Network Design tools | Thu Jan 07 1988 14:53 | 10 |
| Yeah, you could probably do it, but why bother? Just set up another voice to
track the same channel number, but with a transpose set. Then you could set
this phantom voice to have any interval you want, and you can fully specify
what it should sound like. (Let's see now. I'll have the bassoon follow the
flugelhorn a minor third higher. Argh.) Of course, this would get you the
multiphonic effect on every note, but then so would the method you propose.
There are some factory patches in the FB01 that sound two pitches at once: the
one you told it to play and another a fifth above. Kind of spooky sounding,
but parallel fifths get boring real soon.

| You wouldn't use parallel intervals. In wind music using multiphonics,
the chord changes every note. The instruments can't play aribitrary
parallel intervals.
Multiphonics sound totally unlike two instruments playing in parallel.
Recorders can do good multiphonics, too.

| 1129.3 | Fake multiphonics via rapid freq changes. | CTHULU::YERAZUNIS | How about a 40 watt plasma rifle? | Thu Jan 07 1988 15:48 | 25 |
| My Tandy 2000 has a variation of the "munching bits" lisp machine
demo that does something like what you want...
Here's a bastardized version:
FREQ = 100 ; in Hz
MASK = 1 ; just bits, no physical meaning
DO [forever]
F = MIN (FREQ, 80)
TONE (F) ;sounds a tone of F hz for 1/10 sec
FREQ = FREQ xor MASK
MASK = ( MASK + 1 ) MOD 4000
END_DO
With the sound duration of 1/10 second, most people cannot tell
that there is only one note playing at any one time. It tends to
sound very Bachlike. For a few minutes. There's enough order
that your mind can sort of extract a theme and watch it evolve.
Eventually, it gets boring. But what do you want for ten lines
of code, Wagner?

| 1129.4 | or 32000 notes | COUGAR::JANZEN | to cogitate and to solve | Thu Jan 07 1988 16:37 | 4 |
| well, that's interesting. I did things like that with the trs80.
But it's not a trill. Nevertheless, maybe I'll adapt for the 11/23.
I think it could hold roughly 8000 four-note chords.

| 1129.5 | Probably not what you're after, but interesting still | NAC::PICKETT | David - reinventing baroque music | Thu Jan 07 1988 16:46 | 8 |
| FM, hmmmm. Not sure, I don't do it yet. I've gotten some interesting
results out of my ESQ-1 using the AM mode. This produces the sideband
harmonics of a note, and the results can be interesting.
I'd like to hear some woodwind multiphonics. Any suggested listening??

| I have a couple records. If you see a record of new flute music,
it
probably (auto-CR strikes again!) has some on it. There's a little
reocrd with the Bartolozzi book.
