MIDI Hardware Control and Audio Deck Assignment

What is MIDI Hardware Control?

This technology allows ANY MIDI device to operate OtsAV Radio Broadcaster. You can now start and stop your tracks, increase or decrease pitch/tempo, and even crossfade, using a MIDI control device. This means you no longer need to remember lots of keyboard shortcuts, and allows for much quicker song manipulation.

Media that is loaded into a deck using the Stop and Re-Cue feature can be triggered using your MIDI device.

Which controllers can be used with OtsAV Radio Broadcaster?

Any device that has MIDI capabilities can be used with OtsAV Radio Broadcaster. If your mixing panel includes MIDI capabilties, its controls can be setup to control OtsAV.



Most MIDI controllers offer 2-way MIDI communication, which allows OtsAV to control the displays and LEDs on these controllers. These are the recommended type of controller to use. Devices that only offer 1-way MIDI communication can also be used to control OtsAV Radio Broadcaster, however the lights and LEDs on these controllers cannot be MIDI controlled.

What features are added to OtsAV Radio Broadcaster when using a MIDI controller?

  • Familiar controls (same as most professional dual CD players)
  • Visual notification of deck states (e.g. Playing, Cued, Time remaining/elapsed display)
  • Audio outputs can be setup in Old School mode, allowing mixing via two channels on an external mixing panel
  • Start track from Stop and Re-Cue status
  • EQ filtering
  • Navigate Playlist, Work, and History list areas.
  • Load song to Deck control
  • Stutter Play
  • Fine adjustments on Pitch/Tempo/Direction sliders
  • Instant response on all controls
  • All buttons, faders, and jog wheels can be assigned to different functions within OtsAV

Some MIDI controllers also include an in-built dual-channel soundcard. OtsAV can make use of these inbuilt soundcards, including ASIO support.

Audio Deck Assignment (Old School Mode)

OtsAV Radio Broadcaster allows the routing of audio from Deck A and Deck B to two independent audio outputs. In simple terms, Deck A can be set to use one set of stereo pairs, connected to Channel 1 on your external mixer, and Deck B can be set to a different set of stereo pairs, connected to Channel 2 on your external mixer.

The term "Old School" refers to the way in which equipment is connected to use one mixer channel per deck. Using conventional hardware (turntables, CD players, mixing console), the operator usually has to ride the volume sliders on the mixing panel to achieve the required volume levels throughout the broadcast.

Even in "Old School" mode, OtsAV's Dynamics Processor takes care of any volume changes in an elegant manner. Some panel operators prefer to have full control over the mix, and can do so if desired by turning off the dynamics processor. You can now connect your equipment in the same way you would have done using conventional hardware in the past.
