| Hi all,
Hope everyone had a happy thanksgiving.
Right, I am trying to get my AU Compressor to function with host side-chain functions in DP, Logic, Ableton etc. I have set up 2 input elements/buses and 1 output element/bus. In my render function I am trying to establish whether my second, key input bus is connected with if( HasInput(1) ){..do GetInput and PullInput stuff ..} It was my understanding that HasInput() would return whether or not an input is connected or has a callback. This is definitely the case when running the AU in AU Lab; I am seeing this while stepping through the code. The second input bus only returns true from HasInput(1) when the key input is selected. However in all other hosts I have tested in they always return true from HasInput(1). I wish to be able to use the side-chain key input selection offered by many hosts but it seems that the hosts have not been implemented correctly(?). Any suggestions as to how I and my AU determine whether a host has a key input selected?
Many thanks,
Matthew. |
