Ep.42: Sebastian Dittmann from Audiobus (DMT 1-2-1)

Video description:

This week on the DMT 1-2-1 we delve into the world of mobile music making as I chat with Sebastian Dittmann who works on business development at Audiobus.

Audiobus is an iOS app that enables app-to-app audio, allowing users to route an audio signal from one app to another so that you can – for example – play on the Korg iMS-20 synth app as Garageband records in the background. Hundreds of music making apps are now Audiobus enabled and there is a vast community growing around the company’s forums.

I really hope you enjoy the show, have a great week and ’till next time!

PositiveGrid announces their Programmable MIDI Bluetooth Pedal

A very nice move from Positive Grid. Here are the details:

Meet BT-4 Foot Controller

BT-4 is a Bluetooth MIDI foot controller for iPhone and iPad that allows you to control JamUp or other music apps wirelessly.

BT-4 brings the live control solution to iPad®, iPhone® and Mac for just $99. Now guitarists can have a metal case, plug in and play, wireless foot controller at an unprecedented price and experience ultimate tone with the guitar amps and effects in JamUp, BIAS, GarageBand or other compatible applications

Now JamUp users will be able to use BT-4 to toggle between dozens of studio-grade amp and stomp box effects hands free. From toggling amps and effect switches, to switching between presets, controlling Jam Player’s iTunes song playback functions, triggering phrase sampler recording and over-dubbing, and even controlling the built-in metronome or tapping out the tempo, wireless and hands free.


  • Bluetooth MIDI foot controller for iPad and iPhone
  • Solid metal case with 4 assignable foot switches
  • Made for JamUp XT, JamUp Pro XT, GarageBand
  • Send Bank Change, Program Change and Control Changes
  • External expression pedal jack
  • Built-in iOS link for plug and play audio interface
  • Optimized for active/passive pickups for both guitar and bass
  • BT iOS app runs in background on iOS to send MIDI
  • AA x 2 batteries
  • iOS 7 ready

How It Works

BT-2 and BT-4 foot controllers are MIDI foot controllers based on Bluetooth 4.0 technology. They allow users to assign MIDI messages to the controllers by using an iOS app that edits the assignments. Each and every MIDI-compatible iOS app supports a standard communication protocol that enables them to be controlled wirelessly.

These apps can be from the Positive Grid family of products – JamUp XT and JamUp Pro XT — or any other MIDI-compatible app such as GarageBand, OnSong, Auria and so forth. Both BT pedals can be expanded by adding an expression pedal or footswitch using a ¼-inch phone-type jack, allowing musicians to control rotary functions like whammy and wah effects, keyboard sustain, amp gain and volume, EQ and more.

MoMuPro round up of wearable tech for sound

This is an interesting round up of wearable sound / music related tech from MoMuPro. There’s some good stuff there, some older, and some still in it’s crowdfunding stage. It does beg the question about where this trend is going, is it just a fad, or is it more serious?

My view is that this is going to be something significant and that it isn’t going to stop. However, I would add that I don’t think we’re at a point where wearables are fully mature technology. It’ll take time for that.

All the same, it’s interesting to see what’s happening at the moment, and this is a good round up.

This is very cool, and very inspiring.
