Processing Volca bass/keys/beats via aufxdub app?

Post by ammanuel »

Do I need to run the Volcas via midi/audio interface to access aufxdub(iOS)?

I saw a YouTube clip where a Behringer u-control uca222 and usb camera adapter.... It's a bit challenging to grasp the scope of the connections for me at the moment...( can't afford an iOS dock, either)

Any suggestions?

Thank you

I regularly hook my ipad to for both audio and midi for various apps. I don't see why the same things wouldn't apply to that app as it talks about hardware audio input/output (which would mean either the headphone/mic socket, or a usb audio interface) and midi (which would come in via usb for external hardware).

I had a genuine apple camera connection kit, which gives the usb socket needed to hook up usb devices. I bought a cheap ebay lightning-to-usb adapter too and that works just as good as the genuine.

For audio, I use the USB Griffin iMic which gives 3.5mm jack in and out. I could also use a usb cable to get audio output from my behringer xenyx q1002USB directly into the ipad.

another way to get audio into the ipad is to use something like the iRig which plugs into the headphone socket on the ipad rather than usb.

For midi, I use a roland um-one mk2 lead which has a tablet mode switch which runs fine with just the power coming out of the ipad usb. I can use the midi out lead to control a volca (I don't have a splitter to run all 3 yet) and the midi in lead I use with a behringer controller keyboard.

I've tried some different powered usb hubs to try and get both running at the same time as they both need to connect via usb, but no joy as yet.

So in respect of using that app with the volca, you would hook up the audio via either usb or the headphone socket. It reads that the app is midi controllable, but that is irrelevant from the volca's perspective as it doesn't have midi out (unless it has been modded) - so hardware midi control would have to come via some other external hardware.

I use cubasis on the ipad as my DAW, and the audiobus app to route other effects apps into it.

Much appreciate your detailed suggestions and options.

at the moment I have a volca beat, bass, (and keys is on the way soon)...an iPad mini, and Gigaware speakers with ( headphone jack). Trying to keep it minimal ($)

the midi option you suggested seems to be what i should try out Roland UM-ONE MK2 USB MIDI Interface --- via the usb socket of the iPad and one of the midi dins to the midi in of the volcas midi (which would come in via usb for external hardware).
?
The roland um-one mk2 i looked up has two midis...should that matter instead of one?

Is this enough to get the audio out via Volca's headphone using my Gigaware speakers, speakers headphone Jack? instead of Behringer?

Looking forward to any suggestions, and thank you for giving me the leads.

You're confusing a few things there, so hopefully this will straighten it out.

First thing to remember is that there's no usb as standard, so you need some kind of adaptor like the camera kit to provide a usb connection.

Midi isn't audio - midi is note and controller information (eg cutoff, decay etc).

Those midi messages can go either into a device via Midi In, or be generated by and sent out of a device via Midi Out.

The volca only has midi in (as standard), so it can just receive note/controller messages - it can't send them to other devices.

The roland um-one mk2 has 2 midi plugs because one connects to the Midi In on a device and the other to the Midi Out - those ins and outs don't have to be on the same device.

For example, I could connect the um-one to the midi out on a controller keyboard and then plug the other plug into the midi in on the volca. When the usb of it is hooked up to the ipad, and with the right software eg a DAW like cubasis, when I play a note on the keyboard it goes into the ipad, is processed by the app and send to the volca. That lets me record a performance played on the keyboard.

With regards to audio, any audio generated by the ipad needs to go somewhere. it can exit either via the headphone socket or via a USB audio interface (like the Griffin iMic).

The ipad can get audio in either via the headphone/mic socket (with the relevant plug/cable used), or via a usb audio interface.

If you just want to get audio out of the volca, then you would plug a lead from the volca headphone into either the mic on the ipad (via the right lead/connector) or into a usb audio interface if you have one.

to get the sound out of the ipad, you'd connect a lead into the headphone socket or the usb audio interface.

so for me, with the iMic usb, I would have a lead going from the volca to the 3.5mm audio in, and a lead going from the 3.5mm audio out on the iMic to my speakers/headphones.

obviously that uses up the usb socket (provided by the camera kit), so I can't plug in the um-one at the same time to provide midi control over the volca.

Obviously anything going into or out of the ipad can be controlled by the relevant apps eg effects processing on audio in, with the results sent to the audio out, or midi notes recorded/played via the relevant app.

Hope that helps.

Yes, I did confuse several important aspects of midi processing and outputting audio aspects. I Appreciate your clear and instructive explanations. Im learning more from my enthusiastic ignorance :oops:

Great forum with level headed and generous Korgers.

the volcas come with 3.5mm stereo leads that can be used to sync them to each other - those same leads (3.5mm stereo male to 3.5mm stereo male) can be used to connect the headphone socket on the volcas to a usb audio interface like iMic. The leads are nothing special and are available everywhere.

to connect more than one volca at the same time needs some kind of mixing device - that can be either a "true" mixer (which will likely use the larger 6.35mm jacks, likely mono) or something like the Belkin Rockstar, which is actually a 3.5mm headphone splitter but it also works in reverse, combining signals. You control the mix using the volume controls on the individual volcas.

I have have had issues of false sync triggering with the rockstar with certain sounds at high volume, but that problem is easy enough to work around.

you will still need some kind of usb interface for the ipad - as I said before, I've tried both the genuine apple camera kit and a cheap ebay connector and both work just as well.

in the above described setup, if you didn't want to use the ipad, you could just plug the headphones/speakers into the rockstar/mixer.

if you wanted audio to go via the ipad, you would run a 3.5mm cable from the rockstar to the audio in on the usb audio interface (eg iMic), and plug your headphones/speakers into the audio out on the usb audio interface.

Thank you.

I just recieved the Rockstar, and I have a Lightening to USB Adapter. I will be putting an order for the imac today.

Yes, when I used the Rockstar for a beats and Bass ( I synced the via beats out, to bass in) the sound volume for Vbeat was lowered. Like you suggested I used the volume knob to lower bass or increase Vbeats volume output.

Since the Volca is not going to output what AUFxDub processes, I might have to use the iPad to output the audio. I'm trying to put effects ( feedback etc...) on Vbeats sounds.

Always appreciative of your guidance, on this novice journey.

You could hook all that up a few ways depending on what you wanted to process.

if you only wanted to add effects to the vBeats, then you would cable the beats headphones to the iMic audio in, then use an app to add effects, and cable the iMic audio out to the rockstar. The bass could be cabled to the rockstar and you could plug headphones/speakers into the rockstar. You can't record the mix on the ipad that way, but it saves having to add effects to everything.

If you wanted to process everything, then you'd just cable the bass and beats to the rockstar, cable from the rockstar to the iMic audio in, run whatever effects apps you wanted (which would be applied to everything coming in from the rockstar), and then you can use the iMic audio out for headphones/speakers. As it's all going through the ipad, you could also use an app to record it all.

there are some pretty sweet effects apps out there - amplitube and jamup do free versions with a few effects included.

So true. There are some apps which I have hard time resisting downloading. Korg's Igadget looks like a sweet package. Audiobus is one of the most practical and useful ones. I'm expecting it might be helpful to this setup.

I just finished putting in the order for imic. Looking forward to try out your suggestions. Maybe the next step after this one is to get a Mixer ( for sound control or balance), and add a midi keyboard and an interface like Iconnectivity ....

What kind of set up do you have, or do you prefer?

My own preference is analogue/organic vs hard coding everything into a DAW. I've always had a soft-spot for analogue - I've had 2 roland sh-101s over the years and a DSI mopho.

I had made the decision to move away from hardware and embrace the virtual, and had sold off all the hardware I had.

Then I saw a really good deal on the volca beats, bass and keys a couple of weeks ago and couldn't resist. These little boxes do so much for relatively little money.

I use the rockstar for quick dabbles, and a behringer xenyx q1002USB mixer for when I want more options. If I had my time again, I would have got the QX1002USB as that has built in effects. To record tracks, I'm using a zoom h1 sound recorder for ease of use.

This last week I bought a danelectro fab distortion pedal and a korg mini kaoss pad 2 to provide some effects, which I can either cable directly to the volcas or via the fx send on the mixer.

My midi controller keyboard is a 25 key/2-octave behringer uma25s.

As mentioned previously, I use a griffin iMic audio interface and roland um-one mk2 midi interface with an ipad lightning-usb adaptor.

ipad apps wise I have a bunch. I have cubasis and korg gadget for daw type stuff, using audiobus for routing. I also have a bunch of other virtual instruments like korg's ims-20, ipolysix and, ielectribe - along with other synths like thor, animoog, sunrizer, dxi, iMini, iSEM and addictive synth.

All good fun, but I prefer the volcas.

ipad effects wise, I have amplitube, jamup pro and final touch.

I have some interesting other ipad apps that I use - the korg synkontrol app is useful for the volcas - that generates sync that can be cabled from the ipad headphone socket to the volca sync in. It lets you set the tempo, and also provides a swing option. The nice thing with that is that you can press play on the volcas and they wait for play to be pressed in the app.

I mentioned in another thread that I tried MIDImorphosis as a way to take a note sequence I'd entered into the volca bass/keys and convert that to midi so I could store/analyse it.

One final app that I just downloaded today that seems to fit more in line with how I want to do thing is StepPolyArp - that's a realtime arpeggiator which allows complex patterns with midi controller info to be entered and then played relative to the notes or chords on an external keyboard. It seems really quite powerful, so looking forward to using that with the volcas as a way to get more complex patterns playing, without it being hardwired like a traditional sequencer.

the volca sample looks interesting - that would provide a missing link for me in terms of additional hardware based sounds.

Sounds like you have a clean setup ( a novice impression), I'm sure you have invested time, hardware, and experimentation for this setup. It looks like there are all type of revised and reduced outfits released, according to what I hear on forum discussions.

I run into the Volcas by accident. They reminded me of the old acid house, techno, and industrial sounds of the late 90s. The design and color scheme added to the allure :) I was looking for complimentary fx device for djing ( I used to merge, less beat match, ambient, noise, and usually Basic Channel submerged kick for tempo). Once I started messing with Vbeat couldn't help getting the rest. I'm reading up on sound generators, wave forms, and modulation for functional understanding. I enjoy these accidental discoveries on the Vkeys. I started playing few notes and tweaking the vcl, vcl, lfo ... I notice the effects but I don't really know or am not able to duplicate them. I would like to be deliberate (Know what the end would be).

Do you post your creations/pieces/ experiments? ...musical/sonic or hardware?

I just do this for fun and personal enjoyment - I've never put anything online before, but I did upload a simple track I did with the volca trio and then again with the addition of the mini kaoss pad 2 here:

The old New York School of Synthesis videos on youtube are a nice introduction/refresher for analogue synths:

Thanks for the links. Likes the track, by the way.

I also found this link by Beau Sievers. An online midi controller is available for his Guide to Principle of Music synthesis.
