No, I solved it with KissBox (network GPIO device) that I connected to the foot pedal input. With a N.O. relay you can trigger play by closing the relay for say 100ms. It plays on ramp. After the track is done the machine needs some time to preload so that has to be taken into account.
With Pd do you want to use netsend or the deprecated but very nice udpsend from iem? Netsend uses fudi protocol and is not compatible with every device.
