So, I start building a patch. The idea is to record in realtime audio, pitch shift it and then fire the result through the Graham. I start with a simple patch, recording directly from the ADC into an array and then using tabread and tabplay to the DAC. Experimentation with the time shows a semi decent result can be achieved with a metro running at 31.25ms. There is a slight hint of 'grain' but this should be OK when pitched down several octaves.
