Double tap and single tap on AKAI AFX

Hi ashp ,

What I suggest we do is reuse Blue Velvet, but treat it as a black box and just do stuff in a separate module after it has detected single or double tap.

We might also need a module beforehand to force everything to channel 0 - you can just use a Channel Strip here and set remap outgoing to 1.

The routing will look like this:

afx -> Channel Strip -> Blue Velvet -> Custom Module -> afx
                                                     +> destination(s)
    

After Blue Velvet, the note's channel will be set depending upon whether it is a single or double tap as follows:

channel 3 - single tap (byte 0 will be 92)
channel 5 - double tap (byte 0 will be 94)

So, each of the AFX messages we are interested in will be of the form:

92 XX YY for single tap
94 XX YY for double tap

where XX is the note number and YY is the note value

You then need an IF clause to trap each of the messages coming from Blue Velvet and inside each of these IF clauses would contain logic and event send rules. Something along the line of (for example)

# channel 2 button single tap
IF M0 == 92 17 7F
  # do logic and send any events here
END
# channel 2 button double tap
IF M0 == 94 17 7F
  # do logic and send any events here
END

and you'll need an IF clause to handle your SHIFT

IF M0 == 92 01 7F
  # set shift flag here
END
 
You will want an 'NX = XX +B' at the end of the script to block all incoming note events so only the events explicitly generated get sent.

To set an LED on the afx I guess you just need to send a note on/off back to to the afx to explicitly set the LED to what you want. If you want to flash LEDS then you need a loop to do that.

Hopefully, this is enough to get you started and moving in the right direction. Please post here if you need further help in adding the 'meat' to your IF clauses.

PS - there are currently no plans for a windows version, I'm afraid.
