Key-command for "insert tempo at cursor"?

OK, back.

Here’s a snippet for changing BPM using a knob set to CC 24 - Channel 0 - TwosComplement, while at the same time inserting the new BPM at cursor. This will work as long as we are on the Tempo Track.

I’ve followed the instructions given by @Phil_Pendlebury, however instead of creating a PLE (not possible in midi remote) I’ve created a sequence of commands to execute.

I’ve done some pretty basic testing, seems to work well here, but who knows? :slight_smile: However, it can give some ideas to anyone interested into this approach.

var midiremote_api = require('midiremote_api_v1')
var deviceDriver = midiremote_api.makeDeviceDriver('Intro', 'Script BPM', 'Someone')

var midiInput = deviceDriver.mPorts.makeMidiInput("midiInput")
var midiOutput = deviceDriver.mPorts.makeMidiOutput("midiOutput")

var detect = deviceDriver.makeDetectionUnit()
detect
    .detectPortPair(midiInput, midiOutput)
    .expectInputNameContains('your midi input name or part of it')
    .expectOutputNameContains('your midi output name or part of it')
    
var surface=deviceDriver.mSurface

var knobBPM=surface.makeKnob(0,0,1,1)
knobBPM.mSurfaceValue.mMidiBinding
    .setInputPort(midiInput)
    .bindToControlChange(0,24)
    .setTypeRelativeTwosComplement()

var page=deviceDriver.mMapping.makePage("page")

var delayMS=10
var timeStampForKnob=0

var bpmStep=1 


page.mHostAccess.mTransport.mTimeDisplay.mOnChangeTempoBPM=function(activeDevice,activeMapping,BPM){

    activeDevice.setState("BPM",""+BPM)

}

var customVarBPMUp=surface.makeCustomValueVariable("customVarBPMUp")
var customVarBPMDown=surface.makeCustomValueVariable("customVarBPMDown")

var dummyBPMUp=page.mCustom.makeHostValueVariable("dummyBPMUp")
var dummyBPMDown=page.mCustom.makeHostValueVariable("dummyBPMDown")

var ourSequence=[['Navigate','Right'],['Edit','Copy'],['Edit','Paste'],['Transport','Enter Tempo']]

var ourSequenceLength=ourSequence.length
var ourSequenceCustomVars=[]

for(var i=0;i<ourSequenceLength;i++){
    
    var customSequenceStepVar=surface.makeCustomValueVariable("customSequenceStepVar"+i)
    ourSequenceCustomVars.push(customSequenceStepVar)

}

for(var i=0;i<ourSequenceLength;i++){

    page.makeCommandBinding(ourSequenceCustomVars[i],ourSequence[i][0],ourSequence[i][1]).mOnValueChange=function(activeDevice,activeMapping,value,diff){
       
        var i=this.i 
        if(i<this.ourSequenceLength-1){
 
            i++
            ourSequenceCustomVars[i].setProcessValue(activeDevice,1-ourSequenceCustomVars[i].getProcessValue(activeDevice))

        } else {

            ourSequenceCustomVar.setProcessValue(activeDevice,1-ourSequenceCustomVar.getProcessValue(activeDevice))
        
        }

    }.bind({i,ourSequenceLength})

}

var ourSequenceCustomVar=surface.makeCustomValueVariable("ourSequenceCustomVar")


var finalBPMDummyHostValue=page.mCustom.makeHostValueVariable("finalBPMDummyHostValue")

page.makeValueBinding(ourSequenceCustomVar,finalBPMDummyHostValue).mOnValueChange=function(activeDevice,activeMapping,value,diff){
    
    var newBPMInt=parseInt(activeDevice.getState("newBPM"))
    page.mHostAccess.mTransport.mTimeDisplay.setTempoBPM(activeMapping,newBPMInt)

}

knobBPM.mSurfaceValue.mOnProcessValueChange=function(activeDevice,value,diff){
    
    var currentStamp=new Date().getTime()

    if (currentStamp<timeStampForKnob+delayMS){

        return 
    }

    timeStampForKnob=currentStamp

    if(diff<0 || value==0){

        customVarBPMDown.setProcessValue(activeDevice,1-customVarBPMDown.getProcessValue(activeDevice))

    } else {

        customVarBPMUp.setProcessValue(activeDevice,1-customVarBPMUp.getProcessValue(activeDevice))

    }

}


page.makeValueBinding(customVarBPMUp,dummyBPMUp).mOnValueChange=function(activeDevice,activeMapping,value,diff){

    updateBPM(activeDevice,1)   

}

page.makeValueBinding(customVarBPMDown,dummyBPMDown).mOnValueChange=function(activeDevice,activeMapping,value,diff){

    updateBPM(activeDevice,-1)   
    
}


function updateBPM(activeDevice,direction){

    var BPMInt=parseInt(activeDevice.getState("BPM"))
    
    var newBPM=BPMInt+direction*bpmStep 
    
    if(!(newBPM>360 || newBPM<1)){

        activeDevice.setState("newBPM",""+newBPM)

        ourSequenceCustomVars[0].setProcessValue(activeDevice,1-ourSequenceCustomVars[0].getProcessValue(activeDevice))

    }
