Vocoder Help

Hey, have any of you ever successfully used a vocoder in GarageBand? I've got a few different plug-ins and just can't figure them out. If I put the vocoder plugin on one of my "real instrument" tracks with vocals on them, then I see the vocals going into the vocoder, but then I need to trigger the synth (or carrier) to vocode, but of course since it's a real instrument track, my midi keyboard won't trigger the other have of the vocoder plug-in. See what I mean? I'm sure there's a way to do it though.

Thanks for any advice.

Yes, sorry.

I downloaded the demo for Reaktor 5 which has the "classic vocoder" in it. And that's the main one I've got. Then I also have the freeware Zerius Vocoder, but it looks even more complicated than the reaktor one. It could be really cool though. Here are a couple of links for it.

I have not yet toyed with the reaktor 5 vocoder however I do know the Zerius Vocoder. I do not believe you can use it within GB (if I'm wrong about that please let me know). Whenever I have used it it has been as a stand alone application.

Its pretty straight forward though . One file is selected as the modulator file and one as the carrier file. The two combine to create the Vocoder file. I believe you can only use a mono file for the modulator and for the carrier.

Afterwards you can import the vocoder file into GB

what do you mean? I thought GB has 8 inputs these days? Maybe, it takes the ability to record midi and real instrument tracks at the same time though, and I'm not sure GB can do that. Is that what you meant?

But anyway, I was going to post this last night, but the forums were down. I totally had somewhat of a breakthrough. I hooked up a sequencer in the reaktor ensemble to power the vocoder, and it totally worked. It's not the setup I really want, but at least I'm getting somewhere. I'd really like to be able to play my keyboard notes on my midi keyboard, as opposed to programming them in on the reaktor sequencer.

well, someone in a reaktor group said:

"I don't think you can in GarageBand due to the lack of 'bussing.'
You may be running into a limitation of GarageBand here. It doesn't
have the routing that most hosts have."

I wonder if that's true. I know I can record a midi track and a vocal track at the same time, but in order for the vocoder to work, I'd have to be able to link them together somehow. The reaktor vocoder plug-in has the ability to select inputs and outputs, like I would want to output my midi track instrument to the vocoder effect that's in my "real instrument" track, but my lack of knowledge on doing this sort of thing is exactly why I use garageband in the first place. cause it's so simple. but in this case it's simplicity might be making things a lot hard than it would be in a more complex host app.

I just Downloaded Reaktor5 and will most likely toy with it very late tonight.
Its the routing and lack of bussing within GB that has kept me from using other AU's where two signals are needed within one AU. I believe this may be the same situation.

Cool. Yeah, this Reaktor 5 is absolutely amazing. It's also amazingly complex too, but it's worth figuring it out, cause the sounds are top notch.

Anyway, like I said before in this post, at least I can trigger the vocoding with a sequencer from within the reaktor plug-in, so in that way, I CAN get a vocoder sound, within GB, but it's not the best setup.

Buy yeah, let me know if you figure anything out.

Ok, this guy seems to know the answer. And it's GB can't do it.

"What I have to do in Logic and DP FYI is:

Create an aux track for the Vocoder.

Create an aux track for the microphone and bus the signal to the
Vocoder's modulator.

Create a instrument track with the synth you are using and bus the
signal to the carrier.

Create a MIDI track to control the synth. (DP only)

Create an audio track to record the whole mess!

I do not have to do all of this if I use Logic's built in vocoder with
it's built in synth.

GB does not give you the ability to 'bus' audio from one track to
another. It also won't allow you to send MIDI information to a audio
track, which is the only way to get a mic signal into GB. So you might
be stuck."


All well, I might be better off just finding an effect that sounds kind of like a vocoder. I came pretty close to getting what I want just using the robot type effect that GB has in the vocal transformer.
