How the SP handles MIDI
When you adjust any one of the SP’s four analog edit controls, MIDI Continuous Controller (CC) mes-
sages are generated and transmitted on the MIDI Out connector. The information contained in these
MIDI messages varies according to the parameter assignment for that analog edit control. For example,
when the front panel LFO RATE switch is selected, the analog edit control in the Modulation Section
generates MIDI CC data corresponding to the LFO Rate parameter (CC#03). MIDI CC messages are
also generated when you adjust Preset parameter values in the menus; this gives you total control of all
SP sound parameters via MIDI.
The tables on the following pages list all MIDI CC messages and values for the Slim Phatty.
NOTES:
1.TheSPsendsandreceives7bitMIDICCmessagesforallparametersexcept
fortheModulationWheelandFilterCutoff,whichreceivehighresolution,14
bitMIDICCmessages.Thisallowsfornercontrolandsmootherchangesfor
theseparameters.Forthesetwoparameters,theMSBindicatesthe‘regular’CC
number,andtheLSBindicatesthehighresolution‘ne’controlvalue.Ifyouare
onlysending7bitMIDICCmessagestotheSP,usetheMSBchannelnumberby
itselfforthesetwoparameters.
2.TheArpeggiatorClockRateissetbytwoMIDICCmessagesthatcorrespond
tocoarseandneclockrates.ThecoarserateissetbyCC#04inincrementsof3
BPMoverarangeof21320BPM,andthenerateissetbyCC#36inincrements
of0.1BPM.Tosettheclockrate,rstsetthecoarseratebydividingthetarget
BPMbythree;theintegerresult(thewholenumber)willbetheCC#04value.Then
settheneclockratebysubtractingthecoarseBPMvaluefromthetargetvalue
andmultiplyingtheresultby10.ThiswillbetheCC#36value.
Forexample,tosettheArpeggiatorClockRateto121.7BPM:
DeterminetheMIDICCcoarsevaluebydividingthetargetBPMby3:
121.7/3=40.566
TheCC#04valueis‘40’(=120BPM)
DeterminetheMIDICCnevaluebysubtractingthecoarseBPMvalue
fromthetargetvalue:
121.7120=1.7
Thenmultiplytheresultby10:
1.7*10=17
TheCC#36valueis‘17’
ForCC#04=40andCC#36=17,theSP’sdisplaywillshow‘121.7BPM’.
(NotethatinordertodisplaytheinternalBPMontheSP’sLCD,the
ArpeggiatormustbeONandtheArpeggiatorClockmustbesetto‘INT’.)
3.TheMIDICCassignmentsshownforeachsectionareoverriddenwhenPot
Mappingisenabledinthatsection.Formoreonprogrammingandenabling
PotMapping,seepage38.
