I posted this in the Reaktor thread, but in case anyone is interested we just released the update to the Toybox Nano Pack 2, which includes a set of blocks specifically designed to control the Model:Cycles and Model:Samples -->
These blocks are great for using the M:C and M:S in a kind of hybrid set up, using Reaktor Blocks based LFOs and envelopes to control the hardware and then processing the audio with filters and effects in back in Reaktor. You can even control their transport which is fun. Will post some videos soon.
