3.0: This Page Explains a Simple Way to Use "Brain Peak MIDI" for Playing MIDI Sounds With Brain Wave Peaks.

It is easy to connect MAX, Garage Band, other applications, and an external entity via the Core MIDI virtual MIDI port: IAC (Inter Application Communication).

You can create a different setup (1 to 128) for each different IBVA Data channel (1 to 4 and coherence) in the "Brain peak MIDI" and "Brain rhythm MIDI" windows.

Each IBVA data channel can translate MIDI in different ways and send MIDI to a different MIDI port with different MIDI Out Tempos.

MIDI hardware connection.

To play MIDI sounds via an external MIDI entity, you need to install the USB MIDI driver and connect the external MIDI hardware to your computer. Then you can setup "Audio MIDI Setup" that is in the Application/Utilities folder.

If you want to send MIDI to MAX, Garage Band and other applications via the virtual MIDI port then you don’t need any further setup here.

* Virtual MIDI port

If you are running the MAX application it will create its own virtual MIDI port. You need to update and/or reload the MIDI port to access this port.

IBVA4 can create its own virtual MIDI port called "IBVA" when you setup Preferences for the "Brain peak MIDI" and/or "Brain rhythm MIDI".

If you do not setup Preferences in the "Brain peak MIDI" and/or "Brain rhythm MIDI", then IBVA4 cannot create its own virtual MIDI port.

Using IBVA With Garage Band

Garage Band does not create its own virtual MIDI port. All MIDI ports connect to Garage Band already.

Garage Band always monitors what MIDI ports are connected

To send MIDI from IBVA4 to Garage Band, select the MIDI Out port "IBVA" in the IBVA4 application. No setup is needed in Garage Band.

3.1: Setup and Run IBVA4

Setup as 2: Start to show brain wave and Save, Open Brain Note file.

Following explains how to play internal MIDI sound with real time brain waves or how to play back brain wave data.

You can setup IBVA4 in a live recording mode or open a pre-recorded "Brain Note" file to play it.

3.2: "Brain peak MIDI" Preferences

Open Preferences; click "Brain peak MIDI".

Current "Setup" is for NO 1: Maximum 128 different ways to set all of the windows information. And information will be stored into a "Brain Note" file, when you save a file.

To change the Setup number, type the number in the Setup number field, using the Setup stepper or use the popup menu.

Type the name into the Setup name field, and press the 'Enter' key to create the name of this setup. The new Setup will show in the Setup popup menu.

Turn ON "Play AU DLS Synth".

Turn ON "ON MIDI out".

Then start playing MIDI sounds. Tempo 120 is the default Setup. To change the Tempo use the slider, or type a number in the Tempo field or popup menu.

To change a MIDI Instrument click "Pick Instrument" or type a number in the Program Change field, using the stepper or popup menu.

Move the slider for "Peak frequency" to test the input peak frequency translation to MIDI Pitch number as the output sound changes.

Translation adjustment can be made by typing a number in the MAX, MINI frequency field and Number A, Number B field, or you can use the slider to setup the number.

The default play peak mode is "Play note only when peak is in the selected frequency range".

The Input slider range is between 0 and 60 Hz. MINI and MAX allow you to play peak within the frequency range and you can adjust to select "Set Frequency range" or type a number in the MAX and MINI frequency field or use the slider to setup a number.

MIDI play changes happen only when the input slider range is in this MAX and MIN range.

Move the slider and see how translation changes happen.

When you select "Play note - always use peak in the selected frequency range". The Input peak frequency slider's range will change, depending on how you "Set Frequency range", or by typing a number in the MAX and MINI frequency field, or by using the slider to setup a number.

Then by moving the slider for "Peak frequency", you can test the input peak frequency translation to MIDI Pitch number, as it will output MIDI sound changes.

Turn ON "Active Brain data Input" to start translating the actual brain wave peak data into MIDI Notes.

Start to play MIDI with brainwave peak frequency and power. If peak power input is too low, you need to adjust the MAX power number to a lower value.

Select "Play only when pitch changed" which will set MIDI output changes to happen only when the brain wave peak frequency changes.

Try different "Tempo", "Program Change = Instrument", "Set frequency range" to play MIDI sound.

This way there is no need to connect any external device to your Mac.

If you want to play external devices, then select them by the menu option  "MIDI out port" popup.

You can select "Use IBVA data" to CH 1 or CH 2 or Coherence in this popup menu to select a peak.

When you use Coherence, you need to select peak mode to "Use peak in the BS total count at BS CH:" or "Play only when peak BS total count is in the selected range".

Because the Coherence number changes from 0 to 100 % it is very different from the peak power changes. You need to use the Brain switch (BS) function.

See 11: New Brain Note, 13: Brain switch mixer setup, 14: Brain SW inspector for this function detail.

When you select "Active Brain data Input", the peak frequency field number and slider will change automatically, but not necessarily always!

MIDI still plays continuously. To always see the number and slider change, you will need to set "MIDI out Tempo" to real-time.

* If you continue to play the same MIDI note for a long time, the internal sounds from the Mac will stop. Sending MIDI to an external device will continue.

* When using internal Mac MIDI sounds, the MIDI Channel works only for 1 to 8. Each MIDI Channel can be setup for a different instrument. This means a maximum of 8 different instruments can be played from the internal Mac to MIDI sounds.
