Thanks for the reply. I have maxed out all available analogue and digital pins on the Arduino with my project application, including D3 and D4 since I’m not using MIDI. I’m using Timer1 which doesn’t allow me to use pins 9 & 10 (had to change SDcard chip select to another pin).

I suppose I will dig through the library to try to pinpoint which functions dictate the use of the MISO for communication with the Vdsp (unless you know off the top of your head?), I may not require them and could free up the pin. Not worried about any modification to the board traces that may be required. Otherwise I guess I will be learning about shift registers!
