I use ICST in MAx MSP for irregular speaker arrays and it works fine even though it says its "Ambisonics equivelant panning" if you reduce the directivity it basically works like a form of DBAP. It works really well, Ive made sound sfly through mazes and up and down buildings with it. You can even use a normal octaphonic panner to make things fly in a straight line - at the end of the day the sound is traveling from one speaker to the next - the software doesnt know youve placed the software in a line rather than a circle.
