I enjoy experimenting with the NNXT sampler in Reason. Multi-sampling instruments are lots of fun, especially now that websites like the Freesound Project make locating new sounds so easy. This short sequence was an excuse to test out one of the instruments I created, and also an attempt at creating an arpeggiator in Reason 3.0. Apparently Reason 4.0 has one built in, but I haven’t upgraded yet, so I have to fudge it using the Matrix pattern sequencer. If you are still using Reason 3.0 - here is how to do it:

1. Create a subtractor or any synth / sampler, with the patch you want to use
2. Create a Matrix Pattern Sequencer unit
3. Using the patch cord view, connect the Matrix Pattern Note CV output to the OSC Pitch input on your synth. Make sure the synth is connected to the Mixer, or some output (so you can hear the noise).
4.  Then create a 4 or 6 0r 12 (or 32 - whatever) step sequence in your Matrix unit, and give it some random notes. 
5. Hit the Matrix “run” button, and then switch to your synth and play some notes. Your notes should trigger the Matrix sequence.  
6. Because this is not a true arpeggiator, it won’t be in tune in every key. So you will have to choose in-key notes for your Matrix sequence.
