Adventures with the Tascam US-1641

SS gave us a Tascam US-1641 for use in the Mandir. Interfacing it with the Yamaha AW4416 using the midi interface for controlling the bundled Cubase LE4 was quite an adventure.

Getting the digital SPDIF input and other analogue inputs was no problem, though currently the analogue inputs from the Spirit Live 4² direct outs are too hot - they are going up to + 10 dB on the Spirit's sliders! Will need some sort of attenuator.

Midi: the AW4416 is supposed to have a MIDI Remote facility in firmware Ver2. There is a separate tab inside the MIDI screen for MIDI Remote functionality. Got the relevant manual from Yamaha, but somehow the way I did the MIDI Bulk dump was wrong. So, had to change the Hex values of the MIDI messages sent by the AW4416 manually. The readme says that bidirectional control is not implemented - so changing the controls on the computer are not going to move the motorized faders or anything like that.

Changes made: Loaded the AW4416 xml file from Yamaha in the Device Setup Dialog, found one of the faders was working, then made similar changes to midi messages sent by the other faders and switches to get them to work:
faders:

b0 00 fad end
b0 01 fad end
...
etc,

all midi channel 1

switches:

b0 20 sw end
b0 21 sw end
....
etc

works!

20 in hex = 32 = address in cubase. And so on. b0 seems to be some sort of preface. sw must be switch.

The "learn" button inside cubase was displaying the address, channel, etc for faders, did not show up initially for switches. Maybe because the initial setting for the switches was just to send

end

without address or prefix or anything like that.
