Thanks!

My next production will run on CloudT also (or a real M100 of course) 
and will (hopefully) be even cooler!

Yes, this is the nail square on the head.  Anything that requires a

Ah, I see what you mean; no, one-bit sound on one hand and 'normal' UART

Sound, but I think it's become two separate threads; AFAIK we started with

You also couldn't use the UART and the buzzer at the same time given how
this machine is wired up. Hmm.

Honestly, I figure it's at least possible to write a decent monophonic
music tracker program for the M100's internal speaker. Throw in a fast
arpeggiator for chords like they do to save channels on SID chiptunes for
fun. If I was a better programmer I'd try. :(

Re: [M100] M100 Audio / music

[jonathan.y...@telia.com]

Hi All,

Even midi has it's shortcomings though the stream can sound OK if you ignore 
the actual structure of what is shown on sheet music. I play a fair amount of 
Swedish folk music, and the notation on paper is really just a convenient 
notation, and the real music doesn't actually sound like what is on the paper.  
It may be written as 3/4, but the 3 beats get different amounts of time, and 
this actually varies across Sweden.  We talk about 'long one' or 'long two' for 
the beats.  There was someone at the music academy here that actually studied 
this and made a machine to analyze the different lengths of time that the 
individual beats got.  There was at sometime a program that would play the midi 
files that adhered to the paper notation and adjust the timing. I remember 
playing with it once, and it did sound a little more realistic, but still kind 
of stiff. Sometimes you slow down the whole thing at the end of a tune, etc., 
and that CAN be programmed into a midi file but now things are getting 
complicated..

This is actually the reason I bought the T102 I have, as a platform to 
learn 8085 assembly. It is absolutely fast enough to process MIDI. The 
protocol was designed for and proliferated on computers of this era.


In the Tandy's case, the hitch is really getting the UART to go the 
right speed. Last time I tried, no combination of timer/divider 
settings would get it close enough to 31250 Baud.


Yeah, this was my thought also regarding the baud rate.  The closest you 
can get is the divide by 5 option which gives 30720 baud ... about 1.7% 
error.  Of course even if it would work, it also means you need a MIDI 
synthesizer instead of just the M100.

Thanks Alex,

I'm more than happy to stand (sit?) corrected. :-)
And if anyone can convince the M-100 to talk at 31250 baud, it would be 
Ken LOL

Hi Ken,

I highly doubt the M100 could handle such a protocol but the first
thing
I thought of was MIDI; that is *the* electronic standard for defining
and playing music.  Again, not sure if the M100 has the horsepower to
parse or play music from MIDI, but it was just a thought.

Hey gang,

I was trying to use the Linux based tools I wrote to create something a 
little more advanced than WCCARD.BA.  It turns out getting the M100 to 
orchestrate a piece that is a bit more expressive is more challenging 
than just entering the notes from sheet music.  It's pretty amazing how 
much interpretation an artist imparts that isn't on the page when 
actually playing / performing!


Seems like to get a similar affect, I would need to extend my little 
sheet music parser to include expressive components in addition to just 
raw notes.  Makes me wonder how programmers developed music for the M100 
back in the day when the M100 was the only computer they were using.

Hey gang,

I was trying to use the Linux based tools I wrote to create something a 
little more advanced than WCCARD.BA.  It turns out getting the M100 to 
orchestrate a piece that is a bit more expressive is more challenging 
than just entering the notes from sheet music.  It's pretty amazing how 
much interpretation an artist imparts that isn't on the page when
