Some time back, someone posted a short C program for the s300 that played some tune like "Baby Elephant Walk" or something like that. I kept another article that did some basic chords on the system, but didn't save the posting that had the tune. Anyone keep it and care to e-mail or repost? Need a change from instrument control programming, and this might provide some needed relief. -- John Pedersen

If somebody has this I would like a copy as well. I have been wondering how to access the sound chip on the 300.

Three of these have a programmable tone, and the fouth is a noise generator. Someone wrote some low level code to talk to the beeper. I wrote some PSL code that allows you to write music in an easy to read format (See example in the file dbsetup.sl). More recently, I translated the functions into C and wrote a function that would take the lisp lists and generate C data structures that could be interpreted by the C code. Anyone who is running Horizon (nmode? prism? whatever...) should be able to write music immediately. Everyone else can build the example C program and hear what the machine can do. Perhaps someone without nmode will be inspired to write a nicer front end. @//E*O*F README// chmod u=rw,g=r,o=r README echo x - Makefile sed 's/^@//' > "Makefile" <<'@//E*O*F Makefile//' it: music music.o: music.c mytune.h cc -c music.c beeper.o: beeper.c cc -c beeper.c music: music.o beeper.o cc -o music music.o beeper.o shar: shar -c README Makefile dbsetup.sl music.c beeper.c mytune.h > music.shar @//E*O*F Makefile// chmod u=rw,g=rw,o=r Makefile echo x - dbsetup.sl sed 's/^@//' > "dbsetup.sl" <<'@//E*O*F dbsetup.sl//' %Get Compiled C code (lisp:load-ofile "/usr/local/src/nmode/beeper/beeper.o" :libs "") (lisp:ff beep "_beep" :parms (nil nil nil nil)) (lisp:ff noise "_noise" :parms (nil nil nil nil)) (lisp:ff beep-or-noise-duration-left "_beep_or_noise_left" :parms (nil)) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Set up tempo variable and note values %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % (when (null (find-package "music")) % (make-package "music")) % % (setf music::old-package *package*) % (in-package 'music) % % (import 'pnth (find-package "music")) (setf tempo 100) (setf whole 1000) (setf half (/ whole 2)) (setf quarter (/ half 2)) (setf eighth (/ quarter 2)) (setf sixteenth (/ eighth 2)) (setf thirtysecond (/ sixteenth 2)) (setf dot-quarter (+ quarter eighth)) (setf dot-half (+ half quarter)) (setf dot-eighth (+ eighth sixteenth)) (setf triplet (/ quarter 3)) (setf rest -1) (setf r -1) (setf C 0) (setf C-sharp 1) (setf cs 1) (setf D 2) (setf ds 3) (setf E-flat 3) (setf Ef 3) (setf E 4) (setf F 5) (setf F-sharp 6) (setf Fs 6) (setf G 7) (setf G-sharp 8) (setf Gs 8) (setf A-flat 8) (setf Af 8) (setf A 9) (setf B-flat 10) (setf Bf 10) (setf B 11) (setf tw whole) (setf th half) (setf tq quarter) (setf te eighth) (setf ts sixteenth) (setf ts1 (+ ts 1)) (setf tdh dot-half) (setf tdq dot-quarter) (setf tde dot-eighth) (setf tt triplet) (setf scale % (vector % (vector 1 510 770 896 959 992) % (vector 50 540 784 902 962 994) % (vector 100 570 798 909 966 996) % (vector 150 600 811 914 970 998) % (vector 200 630 823 922 973 999) % (vector 250 650 837 928 975 1000) % (vector 300 670 849 934 978 1001) % (vector 350 690 857 939 981 1002) % (vector 390 710 866 945 984 1003) % (vector 420 723 874 950 986 1004) % (vector 450 740 882 953 988 1005) % (vector 480 760 891 956 990 1006) % ) (vector (vector 0 386 705 864 943 984)% c (vector 0 422 722 873 948 0) % c# (vector 0 456 739 881 952 0) % d (vector 0 487 755 889 956 0) % d# (vector 12 518 770 897 960 0) % e (vector 69 546 784 904 963 0) % f (vector 123 573 798 911 967 0) % f# (vector 173 598 810 916 970 0) % g (vector 220 622 822 922 973 0) % g# (vector 266 645 834 928 976 0) % a (vector 308 665 844 933 978 0) % a# (vector 348 685 854 938 981 0) % b ) ) (de get-note (pitch octave) (let ((real-pitch (+ pitch pitch-offset)) (real-octave (+ octave octave-offset)) ) (when (>= real-pitch 12) (setf real-pitch (- real-pitch 12)) (setf real-octave (+ real-octave 1)) ) (when (< real-pitch 0) (setf real-pitch (+ real-pitch 12)) (setf real-octave (- real-octave 1)) ) (vector-fetch (vector-fetch scale real-pitch) real-octave) )) % (de get-note (pitch octave) % (vector-fetch (vector-fetch scale pitch) octave) % ) (de note (pitch octave voice duration) (if (eq pitch -1) % it is a rest;

Each sound is controllable in pitch, volume and duration. Pitch goes from 0 to 1023, volume goes from 0 to 15, duration is between 0 and 255 10msec intervalls. A duration of 0 turns the voice on continuously. A volume of 0 turns it off. The manufacturing specs give details on the programming interface. Here is a summary: The beeper is accessed through ioctl calls. The request argument is either "Send data to beeper" or "Read voice values from beeper". The argument is a pointer to a 4 byte buffer. These four bytes are defined here. R0-R3: Register address field. In the order R2, R1, R0: 0 0 0: Voice 1 frequency 0 0 1: Voice 1 attenuation 0 1 0: Voice 2 frequency 0 1 1: Voice 2 attenuation 1 0 0: Voice 3 frequency 1 0 1: Voice 3 attenuation 1 1 0: Noise control 1 1 1: Noise attentuation F0-F9: 10 bits pitch A0-A3: Attenuation D0-D7: Duration in 10msec's The placement of data in the buffer is a bit srewy: Byte 0 (Frequency 1): 1 R2 R1 R0 F3 F2 F1 F0 LSB Byte 1(Frequency 2): 0 0 F9 F8 F7 F6 F5 F4 Byte 2 (Attenuator) : 1 R2 R1 R0 A3 A2 A1 A0 Byte 3 (Duration) : D7 D6 D5 D4 D3 D2 D1 D0 The volume is inversely proportional to the attenuation. In order to provide rising numbers for rising loudness to the user, we expect a volume and modify to get the attenuation. The same goes for the pitch. In order to calculate frequency of the pitch, use: 83333/(pitch-1023) It is possible at any time to request the time any voice has left to run. This is done by: F4: Read voice1 timer F5: Read voice2 timer F6: Read voice3 timer F7: Read voice4 timer (noise) Noise is generated using a shift register. The following controls are possible for noise: - Attenuation - Duration - Periodic or white noise - 3 shift rates or output of voice 4 as shift rate Bytes 0 and 1 of the data buffer must both have identical contents to control the noise. Attenuation and duration are as in the other voices. Bytes 0 and 1 should look like this: 1 R2 R1 R0 0 FB NF1 NF0 LSB R2, R1 and R0 must be 1, 1 and 0. If FB is 0, periodic noise is generated.

Well, I've gotten 4 requests in the past 24 hours, so I guess it's worth posting: ************************************************************************ Here's the info on the s300 sound generators. I take no credit for any of this, and have never spent time to learn how it works, so I can't help you if you have any trouble with it. Caveat emptor! Some of the source is written in PSL (Portable Standard Lisp), but you could probably translate it to Common Lisp or C or whatever without too much trouble. Enjoy, Gary Fritz fritz%hpfclp@hplabs.hp.com : # # # For those who may not know, the beeper on gators/bobcats have # four independent voices. Three of these have a programmable tone, # and the fouth is a noise generator. # # This shar contains some low level code to talk to the beeper. # There is also some PSL (Portable Standard Lisp) code that allows you # to write music in an easy to read format (See example in the file # dbsetup.sl). More recently, these functions were translated into C # and a function was written that would take the lisp lists and generate # C data structures that could be interpreted by the C code. # # If you can run PSL, you should be able to write music immediately. # Anyone can build the example C program and hear what the machine can do. # Perhaps someone without PSL will be inspired to write a nicer front end. # # # THIS CODE IS PROVIDED WITHOUT WARRANTEES OF ANY KIND.

Can anyone post the layout of these bytes. Thanks! This may not be too accurate 'cuz its based on old documentation (pre-Series 300) for a different operating system (HP Pascal), but it's worth a try. What you have is a TI SN76494 4-voice sound generator; it can make 3 independent square waves plus a noise source. To control one of the square wave voices, the format of the 4 bytes is: byte 1: 1 v1 v0 0 f3 f2 f1 f0 byte 2: 0 0 f9 f8 f7 f6 f5 f4 byte 3: 1 v1 v0 1 a3 a2 a1 a0 byte 4: d7 d6 d5 d4 d3 d2 d1 d0 where v1-v0 is the voice number (00,01, or 10); f9..f0 is a 10-bit value defining the frequency; a3..a0 is a 4-bit value defining the attenuation (volume); d7..d0 is an 8-bit value defining the duration of the tone. Note that the voice number must be given in two places. The f9..f0 value should be 83333 / (desired freq. in Hz); the a3..a0 value is 0 (maximum volume) to 15 (off), in steps of about 2 dB; the d7..d0 value is duration in 10-msec units, or 0 to sound until a countermanding command is given. For the noise source, the command format is: byte 1: 1 1 1 0 0 fb n1 n0 byte 2: 1 1 1 0 0 fb n1 n0 (i.e. same as byte 1) byte 3: 1 1 1 1 a3 a2 a1 a0 byte 4: d7 d6 d5 d4 d3 d2 d1 d0 (thus, the voice number is "11") where: fb is 0 for "periodic" noise and 1 for white noise; n1-n0 control the "noise generator shift rate" as follows: 00 333333/64 Hz 01 333333/128 Hz 10 333333/256 Hz 11 Use voice "10"'s output (don't ask me what any of that means). The attenuation and duration are the same as for the other sources. Somebody please check this out and let the net know if it's OK...

Each sound is controllable in pitch, volume and duration. Pitch goes from 0 to 1023, volume goes from 0 to 15, duration is between 0 and 255 10msec intervalls. A duration of 0 turns the voice on continuously. A volume of 0 turns it off. The manufacturing specs give details on the programming interface. Here is a summary: The beeper is accessed through ioctl calls. The request argument is either "Send data to beeper" or "Read voice values from beeper". The argument is a pointer to a 4 byte buffer. These four bytes are defined here. R0-R3: Register address field. In the order R2, R1, R0: 0 0 0: Voice 1 frequency 0 0 1: Voice 1 attenuation 0 1 0: Voice 2 frequency 0 1 1: Voice 2 attenuation 1 0 0: Voice 3 frequency 1 0 1: Voice 3 attenuation 1 1 0: Noise control 1 1 1: Noise attentuation F0-F9: 10 bits pitch A0-A3: Attenuation D0-D7: Duration in 10msec's The placement of data in the buffer is a bit srewy: Byte 0 (Frequency 1): 1 R2 R1 R0 F3 F2 F1 F0 LSB Byte 1(Frequency 2): 0 0 F9 F8 F7 F6 F5 F4 Byte 2 (Attenuator) : 1 R2 R1 R0 A3 A2 A1 A0 Byte 3 (Duration) : D7 D6 D5 D4 D3 D2 D1 D0 The volume is inversely proportional to the attenuation. In order to provide rising numbers for rising loudness to the user, we expect a volume and modify to get the attenuation. The same goes for the pitch. In order to calculate frequency of the pitch, use: 83333/(pitch-1023) It is possible at any time to request the time any voice has left to run. This is done by: F4: Read voice1 timer F5: Read voice2 timer F6: Read voice3 timer F7: Read voice4 timer (noise) Noise is generated using a shift register. The following controls are possible for noise: - Attenuation - Duration - Periodic or white noise - 3 shift rates or output of voice 4 as shift rate Bytes 0 and 1 of the data buffer must both have identical contents to control the noise. Attenuation and duration are as in the other voices. Bytes 0 and 1 should look like this: 1 R2 R1 R0 0 FB NF1 NF0 LSB R2, R1 and R0 must be 1, 1 and 0. If FB is 0, periodic noise is generated. If FB is 1, white noise is produced. NF1 and NF2 control the shift rate of the noise generator: NF1 NF2 Shift Rate -------------------------- 0 0 M/64 0 1 M/128 1 0 M/256 1 1 Uses tone generator 3 output M is related to the clock rate. The voice start routines return 0 if all is well, -1 if we had trouble accessing the device file for the beeper and -2 if given parameters were out of range: */ #include <fcntl.h> #include <sys/hilioctl.h> /********************************************************************* *DEFINES: * *********************************************************************/ #define ALL_OK 0 #define ACCESS_PROBLEM -1 #define BAD_RANGE -2 #define BEEPER_DEVICE "/dev/rhil" #define VOICE1_FREQ_REG 0x80 /* Top nibbles for byte0 for all voices: */ #define VOICE2_FREQ_REG 0xA0 #define VOICE3_FREQ_REG 0xC0 #define NOISE_FREQ_REG 0xE0 #define VOICE1_VOL_REG 0x90 /* Top nibbles for byte2 for all voices: */ #define VOICE2_VOL_REG 0xB0 #define VOICE3_VOL_REG 0xD0 #define NOISE_VOL_REG 0xF0 #define MIN_VOICE 1 /* Legal ranges for parms from user: */ #define MAX_VOICE 3 #define MIN_PITCH 0 #define MAX_PITCH 1023 #define MIN_DURATION 0 #define MAX_DURATION 255 #define MIN_VOLUME 0 #define MAX_VOLUME 15 #define MIN_TYPE 0 #define MAX_TYPE 1 #define MIN_RATE 0 #define MAX_RATE 3 static int beeper_fd = -1; /********************************************************************* * PUBLIC FUNCTIONS: * *********************************************************************/ /***************************************************************************** * * * Beep using specified voice: * * * * TAKES: * * * * VOICE : from 1 to 3 * * PITCH : from 0 to 1023 (incl) * * VOLUME : from 0 to 15 (incl).

paulc@hpfcrn.HP.COM (Paul Christofanelli) (02/25/88)
Here's yet another program to play the 300 beeper, complete with some
truncated examples. It's not quite complete (e.g., it doesn't play the
noise generator) and certainly not very elegant, but I think it requires
a little less work to get a tune up and playing than the Lisp beeper
player. The interesting thing that I found was that it is able to
pretty much play real-time by reading the notes directly from an ascii
file.
Anyway, unpack the shar file, read the READ_ME and try out some of the
example music fragments. It's kind of fun to type in sheet music and
listen to it, but translating gets a little tedious after a while (which
is why I never finished the pieces).
Also, as usual, this stuff is completely unsupported. Have fun!

To use this stuff, you need to first compile play.c with
cc -o play play.c -lm
To play something, type:
play < playfile (e.g. play < chop.fant)
The "playfile" has the basic format of (starting from the first line):
<key sig>
<quarter notes per minute>
<line of music for voice 1>
<line of music for voice 2 or blank line>
<line of music for voice 3 or blank line>
@.
@.
@.
The key signature is in the form "n#" or "nb" where n goes from 0 to 7.
# of course means "sharp", b means "flat".
Quarter note beats per minute is just that; it's in the form n, where
n is almost any reasonable number. Note that 10 milliseconds is the
smallest duration available.
Music lines come in groups of three (3 voices). A blank line indicates
termination of that group, the other voices are not played. If all
3 voices are played in a group, DO NOT leave a blank line (bug).
A music line is of the form: | measure | measure | measure | ...
(blanks must be present around the |).
A measure is just: note note note ... (blanks must surround notes)
A note is: <pitch>[modifier][octave][length][.][attenuation]
Pitch is: A B C D E F G R
R is a rest. It only needs to be used between notes in a measure
or between the beginning of the measure and the first note.
The program doesn't play anything after the last note in a measure,
but waits for all voices in the 3 measure group to complete.
Modifier is: b (flat) n (natural) or # (sharp)
Note that n doesn't currently work (has no effect); if the note
would be sharped (or flatted) in the key, you must use b or # to
modify it back to the natural state. Double-sharp or double-flat
is accomplished by just using a sharp or flat on a note which
would already be sharped or flatted in the current key.
octave is: 0 1 2 3 4 5 6
Middle C translates to C2. Some choices (e.g. A0) will be out of
range and create squawks.
length is: t s e q h w l x d
t = 32nd note
s = 16th note
e = 8th note
q, h, w = guess
l = 12th note
x = 6th note
d = 3rd note
. means to multiply the note value by 1.5
attenuation is: 0 1 2 3 4 5 6 7 8 9
0 is the loudest.
Only pitch needs to be specified on every note; the other parameters take
on the same values they had on the previous note. The note "parsing"
is somewhat of a hack, so watch out. The only ambiguity is between
the octave and attenuation, so if the attenuation is to be changed, the
octave must be specified. Other than these 2, the parameters can be
put in any order (I think).
There is (yet) no way to handle tied notes. This creates the biggest
problem on tied notes across measures. The . can often be used to handle
tied notes within measures.
Speaking of measures, you'll notice that a "time signature" is not
used in this program. You have to keep track of the notes within
a measure. The measure concept provides a 'reset' point so that the
beginning of each measure in the 3 measure group happens at the same
point in time. Also, the convention that sharped, flatted, or naturaled
notes do not change througout the measure is *NOT* adhered to (it's a
dumb convention anyway).
Have fun, but remember, the program isn't very forgiving!
