Controlling Sampler's "Loop Start" and "Loop End" via MIDI

[eric_c]

Does anyone know if there's a way to control Sampler's "Loop Start" and "Loop End" parameters via MIDI or automation? Like this:



In that screenshot you can see that there are very few controls highlighted for mapping an external controller to, which is kinda disappointing. Is this maybe something you can't do out of the box, but could be done with Max? Thanks for any help!

This would be a rough solution but have you tried going into the MIDI tab of your Sampler device and setting the Mod Wheel controls to those parameters?

Edit: Also in the Modulation tab, for AUX you get an Envelope that you could apply to various parameters including loop start/end. If you set the Attack and Decay to their lowest values you can assign your midi controller to the Sustain and then apply that to loop start/end at whatever percentage you prefer.

That is actually working, thanks! Not as ideal as assigning it to any controller, but it works for now.

Excellent!
I have wanted to do this as well but just presumed it couldn't be mapped.
I don't see why the guys at Ableton don't just let you assign midi to more or less any parameter, maybe they just want to leave their options open for improvements on future versions!!
But likewise I'm happy for now that it can at least be mapped in some way. I'm in the process of making my own hard synth/midi controller, think I will include a mod wheel that is actually just a rotary pot instead, would be useful for this feature!

Oh, I am going to take a look to it, this is the only reason why I did not buy it.

It's a shame it's not possible to do it the way you'd expect considering if you right click on it and choose Sampler -> Simpler you can map the loop start and end to anything.

I think it might have to do with the fact that it is regulated in Samples. Where as the parameter controls are done in Percentage.

Sampler can have multiple audio samples within it, each might have its unique parameters in the sample control tab.

Either way, I have always wanted to midi assign those also.. the only way i had been able to get away with it was the Mod Wheel option and that didn't seem like enough haha.. I had fun playing with the Sustain last night

Aftertouch is another option.. if your MIDI controller lets you assign it to other knobs/sliders.

That would free up your modwheel for other things.

Have you guys seen in the midi tab of sampler? there's a few things there you can assign to midi modulate loop start and end points, the most obviously useful of em might be pitchbend I guess. You might look in to using something like bidule or usine or whatever else to convert the incoming midi from a controller to one of the available midi inputs here. not as good as assigning in the interface, but it's something...

Hello,
Have the same question here...
I have an APC40 and would love to have these "Loop Start" / "Loop End" parameters taken care of by my Device Control knobs.
Ideal would be to be able to assign them with macro's in an Instrument Rack (containing some Samplers...).
Any suggestions/ideas are very welcome.

This is driving me nuts, too. You CAN do this (only in Simpler, though).... but... does anyone else have the problem where the knobs seem to "snap" or "jump" even without snapping enabled, or the Ableton quantize set to None instead of the default "Bar"?

No matter what midi controller I use... Maschine, PadKontrol, E-mu Xboard49.... if I map the start/end points in Simpler or even an audio clip.... they just jump/snap. The only way to fine-tune the start and end points is to use the mouse, which I don't want to do (as we all are trying to get the mouseless workflow minimized).

How come I can't get a nice slow movement for the start/end points using a midi CC or knob?

Does anyone else have this issue?

[yur2die4]

It may have to do with the ratio of the size of your actual sample to the number of points available on the basic CC controller.

If you have a very long clip, and are adjusting using a MIDI controller with Absolute control (non 14-bit), then you in total get 128 points across the entire clip that the control can adjust to. 2 of those are the very beginning and very ending. Although I might be partly mistaken in that, the overall window of control might actually be up to where the clip's end point is?? I'm also not entirely sure if there is a setting for the max/min amount in the MIDI Mode editor (I don't have Live open right now).

Hope this gives you a better grasp on the situation

[hiphopdontstop]

Yes! That is a bit more helpful. Ok... hmm.

So I'm thinking I should at least find the "general" location of the piece I want to chop. Highlight... quickly (and crudely) crop.

Then again, why bother quickly cropping....

I find that Simpler is the quickest way to do crop (as opposed to an audio clip)... because Simpler doesn't warp anything plus, I can "play" the actual pitch of the sample by hitting C on my keyboard as soon as I drop it in (no need to map anything, nor wait for the next bar to come around after I fire the clip).

Just so much easier to hit the key and play with the start point... and then once I find that, tweak the end point... from there, what I do is crop sample...... then "show in browser", then I "slice to new midi track" right from where it's linked from in the browser.

Is this a decent workflow? What exactly do you guys use to initially crop your sample before "slicing to midi"?

[yur2die4]

I'm a Session View kinda guy, so I'm quite used to selecting parts via the Clip Properties, but I'm missing out on the ease of using Arrangement View. In Arrangement View you can split parts using ctrl+e. I think you can even just work with 'the highlighted section' by dragging it.

Edit: I played around a little, apparently there is a "Crop Sample" if you right click on the waveform. Unfortunately, instead of referencing your original sample it appears to create a new one. Also the control really is jumpy haha. I had to hold Ctrl while adjusting the knob to get those fine increments. Either way, the whole situation works badly no matter how you approach it : /

Have you tried using the Pitchbend on your xy touchpad? leave it on Hold. Pitchbend has 14 bit Absolute.

[hiphopdontstop]

Have not tried pitchbend... but, I will say that even if I hold CTRL it makes no difference when using the knob... to avoid jumpiness. Same thing happens. Not true when using mouse... hmmmm

[delicioso]

No need for midi mapping such things these days when you can have python remote midi scripts. The Loop start/length knobs in guille's script for Nocturn works great. No jumpiness and no mapping involved:
