How to create green Apple Loops (Sials) ?

Hm. Either you are thinking too complicated or I don't get what you want to do. 🙂

You can easily create loops within GB by taking a little region of 1 or 2 or more bars and selecting "Add to Loop Library" from the menu. A midi region will turn into a green loop, an audio region into a blue loop. If you check the appropriate boxes and determine the loop's key, both will adjust to the tempo and key if you use them in a new song.

Why is it important to you what kind of loop they are?

As has already been said, you can't convert the audio to MIDI. What you need to do is to transcribe the recorded melody, having slowed it down. The easiest way is to find a friend who has a good enough ear to be able to write down a tune from hearing it (break the recording into small sections).

There is a piece of shareware called 'Transcribe!':
( http://www.seventhstring.com/xscribe/overview.html) which analyzes the audio spectrum to estimate notes.


I've not used it, so I've no idea how well it works, but it is available on 30 days free trial.

Green loops are midi loops, you can create them by turning a software instrument region into a loop. Blue loops are audio loops. By their very nature, you can turn green into blue but not blue into green.

The green loops are definitely recorded via Midi. For drum loops, e.g, you might use a midi drumset to record, but it's still midi. The same with piano - it wouldn't make any sense to record them on an acoustic piano and then use some arcane software to extract midi data.

To record loops as audio only makes sense when you want to use the sound you are recording - all the little extras that can't be captured in midi. They would get lost if you would turn that into a midi file, technical issues aside.

hi
i'm back a little wiser?

the answer of my dealer is: No you can't
it is not possible (yet) to convert a RIAL to a SIAL.

this migth be disappionting but the only ones that can give us a positive answer are the guys of Apple the developers of GarageBand and Logic Pro. they know the trick. otherwise we did not have the RIALs (the blue loops) and the SIALs (the green loops) on our hands.

i suppose that we all ask for explaination to those guys.

we have the possibillity to do that into your accounts here at the forum. just hit the "My Question" button and off we go.

let's do that. perhaps we will get the answer?

You can transpose audio regions and loops using the slider in the editor window. Of course, you can only push the whole melody up or down and can't edit it, and it will sound weird if transposed more than a couple of semitones. But you can do it.

it seems to me, that this issue is more complex then only turning on to a midi thing.

first i downloaded the Apple Loops Utility SDK from the DEV site, installed and edited the source AIFF file. a screenshot can be found here: http://www.notitieblogje.nl/images/Apple-Loops-blackbird.jpg
those small blue buttons makes the 'slices' possible to move even pixle by pixel. you can pick the exact position. that's OK!

when the AIF soundfile was finished i saved it as a Apple Loop in the understanding that it should become a SIAL (Software Instrument Apple Loop).
once imported into Garageband 3 it seems to be a RIAL (the blue one) not a SIAL (the green one), a ordenairy sound sample (loop).

is there anyone who can tell how to make it a SIAL or a midi instrument?

you can make an artist very happy

I really like to make artists happy, but since you obviously started with an audio region, you can't expect it to turn into a midi loop.

thnx for your fast RE Christoph.

do i have to start with a midi source?
that's news for me 😉
i hoped live would be much simpler.

if you have any sources where i can find some info it would be great.

btw: i have an Edirol PCR-M30 midi keyboard on my desk. is that a direction?

this singing blackbird i recorded has the melody i like to use for other instruments.
in a slower tempo, but the same melody.
that's why i like to have a green loop.
it shows the 'notes'.
then i can transpose the notes to the other intrument, let's say the trompet.
after transposing i can change all kinds of aspects of the sound. but that comes later.

after a search i've found things out, really i did.

the question of manfredo132000 can be answered with a ....

let me tell what i found out first:

Transcribe promises to do the job. it does it for a part. the first part to be exactly. T reads a audio file en makes nice curves. but don't ask it to make it a SIAL. it can't.

then there is Melodyne the ultimate plugin for also GB and other apps. those guys promiss you the haven on earth if you like to be a techie. if you like to make music, as i do, it is a little too much.

after some googling around one site told me that the job can be done in Logic Pro. well oh well our favorite brand has the sollution (perhaps).

this morning i had to pickup a wireless keyboard at my Apple Dealer. we talked a little about LP and a arrangment has te made with the LP specialist. if this is really going to work we can finally answer the question. untill then the answer will be: may be.

the story continues

they know the trick. otherwise we did not have the

RIALs (the blue loops) and the SIALs (the green
loops) on our hands.

What makes you think that??

there ARE green and blue loops, right?
the had to be made, once.

when you record a sound it is in the first place analog
even if you use a fully digital recorder.
the 'writing' proces can be digital
or converted to digital as my recorder does.
with that recorded sound we can make a RAIL (the blue one) with the SDK.

now the SIAL (the green on). this one has to be recorded as well. with a MIDI configuration? a keyboard or a software application? i don't know.

my idea is: if you can record an analog sound to a digital file why can't you convert a digital recorded sound to a MIDI file or a SIAL (a software instrument in apples own format).

thnx Roger for this link.
if this is the sollution i will mention it here later.
