Collaborative Creation with Soundcool for Socially Distanced Education

Abstract

Soundcool is a flexible, modular computer music software system created for music education. Moreover, Soundcool is an educational approach that embraces collaboration and discovery in which the teacher serves as a mentor for project based learning. To enable collaboration, Soundcool was designed from the beginning to allow individual modules to be controlled over Wi Fi using smartphone and tablet apps. This collaborative fea ture has enabled network based performance over long distances. In particular, the recent demand for social distancing motivated further explora tions to use Soundcool for distance education and to enable young musicians to perform together in a creative way. We describe the educational approach of Soundcool, experience with network performances with children, and future plans for a web based social network inspired collabora tive music creation system.

jectsinAmericaandinEuropeanErasmus+education
projects,inschoolsanduniversities(Sastre/Dannenberg
2020).Theconnectionofthecontroldevicesistypically
doneusingalocalareanetworkbasedonaWiͲFihub.
However,withstudentsandeventeachersconfinedat
homebecauseoftheCOVIDͲ19situationandonlineeduͲ
cation,werealizedthatthenetworkingcapabilitiesof
Soundcoolcouldbehelpfulindistanceeducation.
In2016wedevelopedasystemallowingtelematic
performanceswithSoundcoolthroughtheInternet
(Scaranietal.2020).Weperformedaconcertcalledthe
GlobalNetOrchestra,withparticipantsatCarnegie
MellonUniversity(CMU)andtheUniversitatPolitècnica
deValència(UPV)(seeglobalnetorchestra.blogs.upv.es/).
However,thissystemwastoocomplicatedtobeused
generallyandquickly,andwehavedevelopedasimpler
systemforonlinecollaborativecreationatadistance.We
havetestedthisapproachbyrecordingseveral
performanceswithstudentsandteachersworkingfrom
theirhomes,showingthatthesystemcanbeusedeven
inthemorerestrictedsituationofCOVIDͲ19confinement.

evenattheexpenseofsomeaddedlatency.
TodeliverhighͲqualitysound,weduplicatedthelocal

todeliverthesameOSCcontrolmessagestoa“mirror”

network.ThenetworkwouldtransmitonlycontrolinͲ
formation.
Normally,OSCistransmittedovertheUDPprotocol,
whichisa“besteffort”protocolinwhichmessagesmay
bedroppedduetonetworkcontentionortransmission
errors.(Peterson/Davie2012)WhilethisisaminorprobͲ
leminalocalnetwork,packetlosscanbedisruptiveover
longdistancesandmany“hops”(forwardingretransmisͲ
sions)aspacketstransitmultiplenetworks.Toensure
reliabletransmission,wecreatedsimplesoftwaretoreͲ
ceiveOSClocally,forwardthemessagestothelocal
SoundcoolserveroverUDP,andforwardmessagestothe
remotesiteusingareliableTCPprotocol.(TCPuses
acknowledgements,retransmissionandsequencenumͲ
berstoguaranteeinͲorder,lossͲfreedeliveryofdataat
theexpenseofaddeddelaywheneveralostpacketmust
beretransmitted.)OncethemessagesarriveatthereͲ
motesite,theyareforwardedlocallytoSoundcoolvia
UDP,makingthecontrolsystemtotallytransparentto
theSoundcoolservers,butallowinguserstocontrolboth
serversasone.(SeeFigure3.)

Figure3.Fornetworkperformance,controlsforlocalSoundcool
applicationareduplicatedandtransmittedreliablytoaremotesite,
whereduplicateOSCmessagesareconstructedandforwardedto
another“mirror”Soundcoolconfiguration.
Asthepandemicisolatedteachersandstudents,we
lookedforasimplewaytouseSoundcool.VideoconferͲ
encesystemslikeZoomallowasingleSoundcoolserver
tosendsoundtoallparticipantswithminimalsetup
sinceparticipantsarealreadyconnectedbyvideoconferͲ
ence.ParticipantsneedonlysendOSCmessagesfrom
smartphonesandtabletstotheServertoenablerealͲ
timecollaboration.Asidefrompacketloss,themaindifͲ
ficultyisthatSoundcoolnetworkportsarenotimmediͲ
atelyaccessibleovertheInternetduetostandardsecuriͲ
typrecautionsinordinaryhomerouters.However,itis
notdifficulttoreconfiguretypicalhomerouterstoallow
receiptofUDPmessageswithspecificportnumbers.
OnlytheteacherrunningSoundcoolneedstodothis
becauseroutersonlyblockincomingtraffic,notoutgoing
messagesfromstudents.Onceportsareopened,stuͲ
dentsfromanywhereontheInternetcancontrolSoundͲ
cool,giventheSoundcoolprogram’sInternetIPaddress
andtheproperportnumbers.
AdrawbackoftheUDPprotocol,again,isthatitdoesnot
guaranteethatmessagesaredelivered.Testsshouldbe
conductedtoseeiftherateoflostmessagesislow
enoughforeducationalapplications.Ourfirsttestwas
doneonJune14,2020inaWebinarwiththeAssociation
ofMusicTeachersoftheMurciaRegion(ADMURM,
Spain)whereaSoundcoolprogramrunninginValencia

TheroleoftheteacherincollaborativeeducaͲ
tion
Thenewteachingparadigmisbasedoninteractionand
collaborationbetweenteachersandstudents.Students
locateinformationwhentheyneedit.Theyhaveadevice
intheirpocketwithwhichtoansweraquestionatany
time.WhythendoestheteacherhavetoofferthemmaͲ
terialthattheycanfindthemselves?CollaborativeeduͲ
cationfocusesontheworkofthementorteacher,asa
guidetoselectnecessarycontent,takingintoaccount
thestudents’interestsandindividualneeds.Project
learningisessentialforthisnewdigitalcollaborative
training.Thisapproach,farfrombeingnew,hasbeen
knownsincethemiddleofthe20thcentury.Thebasic
levelsofBloom'staxonomyoflearning(Bloom1956)
alreadyanticipatethis.Knowledge(theory)andtheunͲ
derstandingandtheapplicationofthesetheoreticalconͲ
tents(problemsolvingandpracticalsessions)arelevels
thatdigitaltechnologyalreadyprovideswithouttheneed
forawiseteachertoprovidethem.However,thecomͲ
plexlevelsoflearning,knowledgeanalysisandsynthesis,
andinnovationarenotofferedbytechnologyalone.The
teachermustbethecenterofthedynamizationof
knowledgeandmustusethemeansthathisstudentsuse
daily.
Foryoungpeople,theInternet,socialnetworksandapps
constituteveryrelevantspacesforsocialization,encounͲ
ter,exchangeandknowledge.ThisiswhySoundcoolhas
beenconsideredsinceitsinceptionasacollaborative
learningandcreationtoolwheretheteacherhasavital
importanceinthelearningandcreationprocess.AsProͲ
fessorDuartsaysinhiseditorial“Internet,Socialmedia
andEducation,““Teachershavethechallengeofbeing
permeabletothechangesthatoccurinthecommunicaͲ
tiveenvironmentandsocialusesoftheInternet.The
truetransformationisfoundintheeducationaldynamics,
intheeducationalprocessthattakesplaceintheclassͲ
roomand,todaymoreandmore,outofit.”Ifyoureally
wanttomotivateandreachstudents,youwillhaveto
understandtheirenvironmentandadapttheteachingto
it.Andthisisthefundamentalbasisforthedevelopment
oftheSoundcoolproject,especiallyasanintegratorof
STEAM(Science,Technology,Engineering,Arts,and
Mathematics–abroadeningofSTEM)forstudentlearnͲ
ing.Duetothisinterest,alargepartoftheproject'sefͲ
fortshasfocusedongeneratingtutorialmaterialsfor
teachers(seeFigure7)sothattheycanusethetoolin
theclassroomoronlineasinourlastremoteconnection

eitherinpersonorinvirtualform.
Giventhecurrentsituationinwhichweareimmersed,
studentscanbereachedatanytime,buttheteacherhas
tobewilling.Itmakesnosensetoclosecommunication
withthestudentoutsidetheclassroom,andacollaboraͲ
tiveenvironmentmustbecreatedthatallowsthisconͲ
tinuousandconstantinterrelationwithallthestudents,
whetherintheclassroomorinavirtualenvironment.
Thisiswhatourtoolofferstotheteacher:placeswhere
theteacheristhecenteroflearningwithouthavingtobe
intheclassroominpersonandwithoutlosingcontrolof
thetrainingoftheirstudents.
TowardSoundcoolasaSocialNetwork
Musicisaninherentlysocialprocess.Soundcoolhas
shiftedthefocusofelectronicmusicfromtheindividual
workingaloneatacomputertoacollaborativedesign
andperformanceprocess.Asweexplorehowbestto
deliverSoundcoolconvenientlytoyoungusersandeven
nonͲtechnicalteachers,wehavebegunacompletereͲ
implementation,movingSoundcoolfromaMaxͲbased
desktopapplication(cycling74.com/products/max)toa
WebAudioapplication(www.w3.org/TR/webaudio/)
runninginthebrowser.Wenowhavethebasicmodules
ofSoundcoolrunninginWebAudio(github.com/rbdanͲ
nenberg/soundcool),andourgoalistoofferawebsite
whereanyonecansimplyopentheirWebbrowserin
ordertouseSoundcool.
OneadvantageofawebͲbasedSoundcoolisthatusers
willautomaticallybeinterconnectedthroughashared
server.Thiswillenablecollaborationthrough:
x sharingandcopyingexamples,tutorials,and
completedworks.StudentscanlearnfromothͲ
ersorpublishtheirprojectstobeseenby
friendsandrelatives,
x jointprojectscanbeundertakenbysharing
modulepatchesandaudioorvideosamples.
Userscancomparedifferentversions,
x groupperformanceswhereeachparticipant
downloadsandoperatesa“mirror”ofthe
sharedpatch.Asperformersadjustparameters,
cuesounds,andmakeselections,thechanges
aretransmittedthroughtheSoundcoolserverto
allmirrors,andallchangesareeffectedglobally.
Inthisparadigm,itwouldnotbedifficultforgroupsof2
to20playtogether,evenwithmodestnetworkbandͲ
widthsinceallaudioisgeneratedlocally1.Weexpectto
makeafirstreleasebeforetheendof2020.
SummaryandConclusions
SoundcoolisaneasyͲtoͲusebuthighͲqualityandvery
capablesystemforcomputermusiccreation.WhileinͲ
tendedforyoungstudents,Soundcoolhasfoundmany
usesinprofessionalsettingsduetoitscombinationof
flexibility,highͲqualitysound,andeaseofuse(see
bit.ly/soundcoolͲpro).Muchmorethanmeretechnology,
Soundcoolwasdesignedfromthebeginningtosupport
collaborativecreation,particularlythroughthesimplicity
ofcontrollingmodulesusingsmartphones,tablets,and
WiͲFi.
ThecontrolofSoundcooloverWiͲFiledustouseSoundͲ
coolasthebasisforcollaborativenetworkperformances,
sendingSoundcoolaudioandscreenͲsharingtoperformͲ
ersusingaZoomvideoconference,andusingInternet
connectionsfromsmartphonesandtabletstoSoundcool
forcollaborativecontrolbythegroup.
Thecollaborationsandperformancessofarhavebeen
veryencouraging,includingaperformancewithschool
childrenfromMadridandwithteachersfromseveralcities
fromSpain.Welookforwardtomoreperformances.
Inthefuture,weaimtomakecollaborationandinteracͲ
tionevensimplerbycreatingawebͲbasedversionof
SoundcoolthatwillbeinherentlynetworkedandinterͲ
connected.ThiscontinuationoftheSoundcoolproject
willmakeiteveneasiertosharemedia,sounddesign,
patches,andrealͲtimecollaborativecontrolatadistance.
Soundcoolhasshowngreatpromiseasaninnovative
approachtomusiceducation,awaytoexposeyoung
studentstothepossibilitiesofcreativeandexperimental
electronicsound,andapowerfulmeanstoenablecolͲ
laborativecreation.Givenourcurrentneedforsocial
isolation,Soundcoolhasbecomeavehicleforbringing
youngperformerstogetheragain,bymakingnetwork
performancessimpleenoughforteachersandstudents
withoutextensiveknowledgeofnetworkingandcomͲ
putersystems.WelookforwardtomanymorepossibiliͲ
tiesformusicandeducationaswecreateaWebAudio
versionofSoundcool.
