Macro: Asking for a pitch state on a specific track

[DanielAkerberg]

Hello,

I am trying to create a macro where I can use my Lanuchpad toggle a tracks Pitch state on and off, and at the same time send visual feedback to the control surface. Here is my initial draft. Logelloop does however not like the use of TrackPitchState in the If statement. Could I please get some help with how to proceed with this? Thanks!

If { TrackPitchState == 0 }
TrackPitchState trk1 1

MidiNoteSend 11 1 1 “Launchpad mk2”
Else
TrackPitchState trk1 0

MidiNoteSend 11 0 1 “Launchpad mk2”
EndIf

Hi Daniel,
This one is a bit tricky ! -)

In Logelloop native macro examples, you will find “Track Settings Copy And Paste”.
In this macro you will see how we get the user interface state when there is no variable to share the UI state.

To get the state of the Pitch of track 1, you put :
valueOfReactionNamed(“TrackPitchState_trk1”)

This value can be directly put as a value in the midiNoteSend line after being scaled.
So, the scale expression below will convert a value of 0 or 1 to 0 or 127
scale(valueOfReactionNamed(“TrackPitchState_trk1”), 0, 1, 0, 127)

As Midi values must be integers, you need to convert the float value in integer using the floor expression :
floor(scale(valueOfReactionNamed(“TrackPitchState_trk1”), 0, 1, 0, 127))

As we do not want to cause too much communication with the Midi device, we have inserted a “Sleep 100” in the evaluation loop

The final macro will look like this :

//************************************************* Macro Begin *************************************************
DoRepeat
Sleep 100
MidiNoteSend 16 {floor(scale(valueOfReactionNamed(“TrackPitchState_trk1”), 0, 1, 0, 127))} 11 “X-TOUCH MINI”
While true
//************************************************* Macro End *************************************************

I will try to insert a native Midi feedback for all tracks states in a future Logelloop release.
Best regards,
Philippe

Thanks, I’m also interested by this kind of macro,

when i make “verify” your macro i have this error:

Ligne: 4, Commande erronée: MidiNoteSend
Bad parameter :The number of parameters (5 instead of 4) is incorrect for MidiNoteSend

An idea ?

[Philippe]

Did you put the device name inside “…”?

If yes, that should work.

Maybe, you can send a green copy by email.

yes,
after some testing, i discover it was a copy/paste issue
when i paste your code, the ” characters was copied in black, when i rewrite them , they turn (with their content) to green
and no more errors in verification process
Maybe a pc/mac issue ? , I’m on mac Mojave.

Now about the macro itself, if i start it , the pad light up, but no variation when pitch change ( or maybe i misunderstood something)
tested with x touch mini and launchpad

there ‘s a tricky interaction with Launchpad colors, they change depending only with specific velocity values

[Philippe]

Ha, to obtain a feedback from the pitch value, you need to associate a Midi controller to this pitch and the feedback is already working for the pitch value.
Do you need something more particular?

I Will probably need more explanations about that. Maybe a video?

I will look at the copy/.paste issue.

ho, it’s ok,
i first think the author of this post want to have not only on/off feedback but also color variation depending of the pitch 😉
about color, i ‘ll send you the info i know

[Philippe]

To get the pitch value, you need this :

{floor(scale(valueOfReactionNamed(“TrackPitch_trk1”), 0, 1, 0, 127))}

But you will need some math to obtain the color variation depending on the pitch value… -)

ok, so i try to post the macro here, but was considered as spam..;-)

so here a link if someone interested
i use second row of a launchpad mini (mk1) to control the reverse
third row the pitch on/off
