this is what the audience will meanhearing in the san francisco opera house the sound of warning for an organelle this is what the musician will beplaying a little apple chutney computer was a hardware/software language calledyou draw 100 computers can make beautiful music fanswill find out today on this edition on the computer chronicles the the i'm are well the computer chronicles is madepossible by leading it makers ibm-compatible computer systemsincluding lotus look-alikes reggie

word processing the spelling correctioncommunication software and he's compatible 1200 baud modemleading edge with over 1000 service centers nationwide additional funding is provided bymcgraw-hill publishers a bite bites detailedtechnical articles on new hardware software and languages coverdevelopments in computer technology worldwide the welcome to the computer chronicles i'mstewardship hey this is gary killed all

in gary this is the casio sk1 his computer keyboards really come along way in two years since we last initial and computers music this littlethink us about a hundred bucks does all the usual things as a built-insynthesizer and watch what else this little guy can do it has a digital samplers so thatcomputer chronicle computer chronicle yeah carol you can do anything you wantwith this keyword it's quite amazing it sees me one of the reasons computers andmusic i moved along so quickly is because of the establishment of astandard in this case the many standard

poster at the mall personal computerindustry is really based upon standards starting with a floppy disk in the earlyseventies rs 232 the idea motherboard processor isoffering systems languages all these things our basic standards that we've all hereto admitted standards gonna give us a whole bunch a new interesting and fun application forwe're gonna see some others today we'll take a look at the commodore amiga theatari st see what kinda music you can get out at those machines

we look at the new apple two gs and seehow good it is with music and sound we're going to start out by going to acomputer expo which had a concert featuring amacintosh i'm on yeah leuenberger is a musician a composer a writer and performer withthe synthesizer he can mimic any traditional instrument and invent afew new ones as well the equipment that makes it possible isa combination of software and hardware that communicates with a synthesizerthrough a musical instrument digital interface or midi port theprocess begins

on a macintosh screen with a programcalled professional composer to lay the foundation for peace theprogram counts out and automatically numbers themeasures creating a musical sketch on which he plays notes gary can then move directly to hiskeyboard the output of which means into the macagain through a midi port what's the roughdraft is in the machine's memory you can be played back and manipulatedwho carries a digital sequencer with 8 midi ports to assign different voicesto

8 separate synthesizers if he answeredrun park the midi clock will synchronize the beach is itempowers the peace i start the drum machine and i when i fine-tuning is completed the mididata goes to a yamaha digital sequencer which controls theplayback at the completed piece through the 8sympathizers gary can still change the pc any point or play along in real time room

the synthesizers began to appear in thenineteen sixties and found a special nation in themusical world over the next decade now with the admin midi electronic musiccan take center stage 1 them on do well joining us now in the studios chrisfrench music software consultant

activision sitting next to chris's bob moorepresident of hybrid arts in los angeles gary sir it is a really looks like examplethe midi application is a music studio to send the dollar package runs on the atari fight yest them but tocompose and playback music circus commercials for products sure beglad to mostly operations are done just with the mouse alone the nurse wholeft the back room is real time feedback as you move a note on the staff that'sright as you move the no

up and down the staff you can hear thecomputer play that no and it also tells you from the message board with a notice i can select most music notation ameasure bars ties about 15 different instrumentcolors to work with to distinguish oneself from another a triplets accents dotted notes and here i can select allthe notes from hold to a 30 second now and that's withtemples from 57 corners a minute to 200 corners and just quite fast we havearrests

i can put an accidental a note to changeits key or stay in the currently if not we willall the features in the composer will be using just about all the notations shows a piece of music that would play justusing the atari so much of himself once again distract the mouse up to filehit song files and i want to load a song download asong called and vision which you have your own yes i composes imade up my own sounds with the software and then compose withno case different color here's a different sound

to now take the mouse cursor down toscroll and musicals home okay now we're just using the attire nothing else that's correct the cells inthe ataris play on the business up for sale him and now you got me into eyes overhere introduces other players and tell me what you doing okay these a midiinstruments were using a midi cable out the back on the atari st which is the many pores built-in and we're usinga casio cz 101

a tone generator from yamaha quality x7 we've got a latin percussion drummachine and a regular trap set drum machine these are all midi instruments and the notes will tell the mediaservice want to play as a music is being schooled by okay so soonreynoso orchestra by 40 k adult this song with the trash can goback to my file sound files on a lotta song i actuallythis was a popular song call axel f from themovie beverly hills cop up this is not the original recordingthough i wrote this music on the screen

found sounds in my synthesizers and drummachines that i thought matched the original song and wrote on thescreen saver to disk and this is what you get from the deserve our daughters that is a music that is being read andmany data spit out to the machines for how long it take in thisonto the about three and a half hours at-bat but bob was turn you know whatwhat is hybridized what kinda music productions wemanufacture a whole series of products for the 8-bit our computer and the16-minute our computer

you have something called adapt rightaid app is a system that we refer to as the tape was recording studio or digital audio onwards you showed us andthis is their yes ago ensure okay let's do it themusic studios a softer really for the consumer market understand bob you haveproducts for both consumers and professionals can show circles are broad sure i'llshow you are still easy track you track is a program sells for 600dollars in the make a chain stores press easy driveable to start and stop

the drum machine within the synthesizerchange patches status this machine are sends commands to this synthesizerwhich is another computer to change patches make voice changes inand start shock trauma centers are things like a stopper by 12 and continue on louis cook some real work easy track isdoing with the casio keyboard sure what he's a truck is able to dohere's i'm able to turn tracks often on you'll get a recording studio yearswhich ryan

southern girl is commenced yearly playedmusic back in my view record the resultant sure my concern southerngerman shane play a part keep that here that back you see the part that ijust played there 2012 at a national auto correct thetiming on that truck to crack to assess sixteenth note fromthat rock to that track replace it players knowthey the time he's been trying to give otherthe high and you got paid out what to do paid app allows me to take well

replace tape i'll about us a depositionsix-minute recording system that for the most part in our eyesreplaces tape machines and that's our eventual goal is actually replacetechnicians the tape this recording studio way to pierce the version i but with meis a two-channel stereo on high and plus for type dbm input are recording system sixteen-bit areright now this person i'm showing a cd compatible with a professional system call todiscuss

on well if you'd 12 as far as somecompetitors were planning within five years to really such a system appear onthree three hundred thousand dollar something like that on our system our system the law and sis miss twothousand dollars sciences in asotin remember our when we going with the cd player cdplayer i can start from here and it's a sound source the stereo outto this or patch the stereo inputs have our recording system recording systemtakes the analog information from here digitizesit saves it into round and i can play

that back to manipulate that information business captured the sound right afterright playing from here member on capture that sound i can graba section if i wanted i can zoom in if i want to take a close look at what i'm about tocapture i can scroll that around grab a section listen to that so this is sort of like the equivalentto the word processing system but for music instead right i can grab a section place it inyour also the song i'd like to

so you can make any audio source put intheir massager play with sure music than actually this system is a lotmore than just a recording system or also able to take other functions such as anoscilloscope by 12 or a mixing system status reply on thelaw for city for truck over logging on to learn we're at it i'm afraid okay gary we seewhat you can do with an atari st just a minute we're gonna see would you do withthe media and the new apple two gs if you'reinterested music to stay with us

dogged well now replaced all the major machineshere for another demonstration avenue yurman being that's chris potter ofmedics cooperation the new synthesizer the yamaha dx 100 inthe new computer the commodore amiga across as a partner in software productyour call soundscape american shortest picture some sleep offers the recordingenvironment texas music operating environment that allows me to play upwith up to 16 external synthesizers as well as using internal sampled soundsi've got a little piece in here that'll play the you busy playing in the play apiano

i'm hoping do is take the sound andwe're gonna release examines mine last year deletions millioninternally he's a little sounds like bill useshundred-mile so go in as i choose different optionshere you can see the breeze menus pop up and there are many many options withinsoundscape environment going to sample that's the current asounder the organ that was in there i'm gonna go inand sample wine glass should have the wine glasses created anew voices inside and i gotta remember

to turn off looping here there we go and and you can see it says new sampleappear now playing back the pm's manasquan class on the the meat isparticularly well suited for this because it has for digital analog girl converters in it so i can play backsounds very well also in addition as i'm gonna sound i can have a background task in theright hands meters graphics running in the background anne's couldactually be edited

and played around with him not conductlegal in play with the pictures in santa cruz the sampling minus public display blog the honey was a better quality centeredsample all it seems less quality sound perfectly and good for the home studioare you're able to do you know sampling and sample your catdata matters what was the cost the soundscape insists the soundscapesystems 149 dollars for the system and that concludes all the modules haveseen the sample itself is a small box here the plug straight into the porttenants another

ninety nine dollars with software thiscould be used by the amateur musician at home or even more professional yes it's already beingused by several professional musicians and offers unlimited over trackcapability limited only by memory and security related by a limited bytime yes thank you very much in gary we're gonna go take a look now at thenew apple two gs and see what kinda music weeded out a bit ago thank you chris sitting here patientlywaiting for us has been curtis sasaki curtis is the product manager for thetwo gs an apple

stir we're seeing the but attentiongiven to the amiga and atari because the sound processing capabilities and i'll get a chance to see theoffering from reese nothing from apple's call the apple two gs i guessthe g stands for graphics test for sound clear tells about occurssure what we did well done is we've got over the insightex sound chip from ross keyboard input is part of theapple to gs so that allows us to do both digitizingand synthesizing those songs and music well play is a sample of a

contactors play because this is a good to see more ofthe company this is stored in memory that's correct yes okay you can use orin memory foresee that onto a floppy disks with them which was the capacityhow much can you store and digitize up to as much memory happens tosystem the apt to gs together eight megabytesmemory taken away from the atlanta this particulars sequences along the same this is a busis anarchy in length in this how many seconds but twentyyears as

okay and this demonstration you showingasus is in a particular software product this is just a demonstration program itshows how you can digitize sounds that surround upon by this particular thingwhen i n but what about the synthesizing andsynthesizing you try for me with a program calledmusic instruction set was brought on on original apple to the programmer willharvey has had quite a bit of fun with the newmachine in psych sound chip the rhythm is a construction site is towhat you basically to make up the music yourself on the machine and playbackdigitized and play back to them

actually you you compose music on the i musici and he's in screen herewhen you load in is a sample you're pulling a file the songs are inthe norm that's correct so you can see in those on-screen score send you plant and and all those icons on the rightwith the usual composition described am right things pending in the big difference betweenwhat you do now and what you could do with music instruction set an apple toyield

powered original version on theopportunity to play for voices this logically 15 voices of dissent closer to some processing there was a attorney good we believe him 30 powerful force partner engineeringalive and playback that me my sons okay curtis thank younow see what the apple two gs can do we've seen lots of computers that canplay music now we're going to take a look at a computer that can listen to music wendy was asthat report from stanford researchers at

stanford center for computer research inmusic and acoustics are trying to imitate the human yearwith a computer program specifically the computer must not onlyhear the music but distinguish between several notes orharmonics played at once in this experimentalpiano solo was recorded through a microphone ontotape researchers wanted to find out if the computer could play back the performance with theidentical pitch rhythm and harmonics the experimentrequired artificial intelligence

so the powerful programming languagecalled list was employed the resurgent else trying to find thealgorithms which say imitate how are your understands musicalsignals so using less we have a good workbench a or to match for for this kinda forexperimentation the tools also included a minicomputersignal processor and a synthesizer this was the result the piano is heard first followed by thecomputers reproduction accompanying the piano music

another part of the software will try toscore for the music and printed out the entire process ofanalyzing one thirty second piece of music takesan entire afternoon for stanford's only manycomputer but is faster more powerful microprocessors reach the market the process could happen lifetime forthe computer chronicles: i'm wendy wood's on dubbed well joining us now on studios davidschwartz president of compu sonics a

palo alto calif and back with this is george morrow arefrequent commentator in some time poster sorus wanna mention we finally got allthe computers on the ibm pc her i the something else that i thinkthere's it's important to point out here there's there's a product to david hascalled copy sonics and it's a recorder as i understand itwill have to explain a lot more about that these two pieces of equipment onnormally go with rosanna spar the editing system is also shows

so there could you describe the cut tosize well the compass on xd is p1000 is the world's first optical disc audiorecorder so i'm like tape recorders or any othertype recording device you've ever seen beforethis machine records on rotating computer memories discs this isan optical disc using the computer industry forrecording say insurance company data records are maps or whatever oil companyrecords in this case we've recorded music youcan actually see it recorded on the disc air school thisfall

missus yeah but think it's important topoint out that the compact discs that people are areused in our diesel chase over things are are a their what'son call read-only memory and those can write on mostthings you can't record on time and so this is a this gives you the basically a call youa cd audio but your body record on also good that'simportant dates recordable and and not just recordable recordablein a permanent way i'm not sure if you ever take wear outon you or jam or get destroyed or

something like that are just plainfollowing are more than that i mean you can massage and manipulate this music onthe disc once you've recorded the can shove cordial its data your show is data now this is a programarm that we call the dsp 1000pc programwhich is a software disc for the ibm pc will also be available for the applemacintosh very similar form course in black and white and itallows you to list the tunes on a disk database themif you will play them from the function keys on theibm pc

keyboard but i think even moreimportantly up process the data and that is a process like eq boostingthe mid-range a reducing the level at the base for example orlet's say they're you have noise on your initially under it will this key here process that wasthe process k we move to a noise removal process korean whichautomatically searches the data for impulse noise is a computer foundthat that blip exactly this right here is probably ascratch on-the-record that was recorded ofcourse in the data on the desk

then the computer proposes to replacethe scratch with the average signal from both sidesat the scratch ca and of course you listen to that andif you agree with the computer software you push the f-type 10 key and remove it and you arethat this music you recorded i think on this come back to sleepies music fromearlier in the show danger yes i did i was up in your control roomtroy to do that for singer york's old ago old intensities as it was earlier

does a midi synthesizer these the sizein a computer and then fed out analog and right into the input jacks onthis crucial george i want to ask you 90 yourcollective sending record with a lot of scratches on men's ryo when he see you could do something alsoi for small story i think i could probably take the worst to noiseon my records i can restore these the lot is historic recordings tosomething close to what they were in the very beginning but but then i'llwhat this makes possible is something much more than that a

if i did some analysis about the early acoustic recordings and then could takeout the effects are those horns then perhaps we could hear some of thoseearly recordings as a minor actually sound in the studiosit is one of the most exciting things that you can imagine what was the marketfor this machine other room where guys like to murder have well it's really for people at thetop and the audio market audio files were extremely serious about their musicand ford just like monroe said a seven thousanddollar recording devices the state of

the art and recording except i canafford what is the person the millions of rightnow these are a hundred dollars each and the record about 80 minuteshave stereo on one side or are slightly moreexpensive disk recording eighty minutes on each side david one last question just put out atime to see this thing ever coming down in price were really does become aconsumer item i see it coming down an order ofmagnitude that is to seven hundred dollars providing this e-mail conceptbecomes a little more popular

now they're just introducing it daviddressing george thank you are at a time thank you for joining us will be back injust a minute with this week's computer news the world i'll tyson chase sitting in for stewardship a in therandom access file this week lookout for commodores latest promotionefforts amiga computer the price of an amiga 1000 system with acolor monitor and 256 k memory ball between five hundred andfourteen hundred ninety dollars
