Reason’s Dr.REX in a Combi

Many Reason-users have asked me how to trigger a Dr.REX device from within the Combinator-device in Reason. Well, the answer is probably easier than you would think 😉

Please download my example-file first, here:

As you can read in the MIDI Implementation Charts.pdf (should be installed with Reason on your system) a MIDI key 26 (D0) triggers the whole loop. Aha! So therefore the most simple method should be using a Matrix in the Combinator which triggers the same note-value.

In my zip-file you will find the DrREX-trigger.cmb which shows one example of this method. During patching for Reason 3, one of the sound designers, Peff, found the CV value for this key-note.

This works nicely. Please check out the PATTERN parameter also. With this control you can play just a few steps of the loop. If you start hearing flams or phasing, this is caused by a slice who’s triggered just before the loop starts repeating.

As you might understand, this method is a true hands-on approach 😉 It makes ‘playing’ with loops more fun.

I am planning to release some Combinator-sets which show new possibilities using this method.

Good luck experimenting!

    ja inderdaad er is niets onmogelijk in reason ik heb wel een vraag over de reason record is dat programma compatible met een digitale mixer om er externe samples van synts of drumcomputers in op te nemen dat zou fantastisch zijn…

    @henk: helaas voegt Record daar niets aan toe. Het is slechts een vrij basale multitrack recorder. Sample of loop-editing moet echt met een externe applicatie gedaan worden.
