Mulitple Midi Devices

Ive just started using renoise for about a week now and in my set up i have an mpc1k, a few synths, a midi controller and another sampler/drum machine. I have my mpc at set up as a slave, but i dont really see how i can midi up my other devices so that i can have renoise triggering my 4 or 5 other insturments all at the same time. Ive read thru the forums a bit, but could not find much on this.
Also, i read that renoise is going to have a audio record function soon. Does anyone know when this will begain and if the price will go up for the program?
This is my first tracker program and its really neat. Im starting to like it alot.
