Been working out a PE Tracker based mobile setup for some upcoming travel while staying fairly minimal and with the ability to be fully battery powered at times. The tracker mini will of course minimize this even further but until then this will do quite well. Below is my setup. Curious to see what others have come up with.
Tracker powered by iPad Mini.
Bidirectional midi between tracker/ipad via usb.
Audio from iPad into input of Tracker.
Using Tracker to sync, sequence and sample a variety of iOS apps.
Tracker audio out to Bose S1 Pro Battery Powered PA Speaker or wired earbuds.
iPhone & Shure mic & little collapsible tripod for found sound sampling.
USB Micro SD Reader for loading found sound samples to Tracker’s SD card.
CME Widi Jack for those times I want to use the iPad as a wireless midi controller for the Tracker.
Battery bank with solar charging capability.
The key to this setup is really the CableCreation iPad hub that supports downstream power pass through so I can simultaneously power the tracker, have bidirectional midi and run audio out of the ipad into the tracker.
