The Doctor Will See You Now
The notes are E0 - B0. D#0 will stop all loops from playing. By putting multiple Dr Octo Rex's in a combinator you can control them simultaneously. We can also add a lead sound to our combinator so we can blow over the grooves we create with the Dr Octo Rex's.
What we will do is put 3 Dr Octo Rex's in a combinator. Eacn Dr Octo Rex will represent a column in our table above and each loop slot will represent a horizontal row. For example in loop slot 1, I will load a verse loop each of the the guitar, bass and drums Dr Octo Rexes. In loop slot 2, I might load the chorus loops and so on. We can even keep a loop slot empty to keep a part from playing - handy for breakdowns. Ready? Here we go!
Step by Step
Press F8 to bring up the floating device window and drag in a 14:2 Mixer, then drag in 3 Dr Octo Rex's. Just leave the default routing in place. If you only have two parts, just use two Dr Octo Rex's. I am going to use loops from the Reason Soul School ReFill, because they are set up to work together nicely in this fashion, but you can use loops from any source. Then bring in an Nn-xt or synth of your choice and load it with your favorite sound. I'm going to use an NN-XT loaded with a harmonica sound.
Click on the thumbnails below to see the top and bottom half of the combinator so far.
I'll fill loop slot one on each one with my verse loop, loop slot 2 with my bridge. Loop slot 3 has drums only, and loop slot 4 has drums and bass only. I'm using the "Cinicinnati" loops from the Reason Soul School Refill for an old school James Brown funk feel.
I also added a Scream 4 distortion unit to the 'drums' Dr Octo Rex, just because I love to use the tape distortion preset on drums. I feel it adds some warmth and kick to the loops. I like to start with 'HalfInch' preset from the RFSB (Reason Factory Sound Bank).
If I was playing an EWI4000s (or really any wind controller except the EWI-USB), I'd be good to go due to the extended range of these instruments. However, I have my EWI-USB set so the lowest notes are in the C1 range. Since I need to trigger notes in the E0-G0 range, I need to somehow transpose those notes down an octave. I can do this in the Combinator programmer section. If using an EWI-USB, follow these steps:
- Click on 'Show Programmer' on the front panel of the combinator and select the device labeled 'Drums'. I set the 'Transp' parameter to -12. This means that the MIDI notes will be transposed down one octave before they are sent to the target device.
- Set the Key Range Lo and Hi for the dums to D#1 and B1.
- Set the Key Range Lo and Hi for the other Dr Octo Rexes to C-1 to B1.
Now, I don't want my harmonica patch to play when I play the loop switch notes, so I will set its 'Key Range Lo' to C2 and leave the Hi alone.
E0 - Slot 1 - Full Band
F0 - Slot 2 - Full Band, variation
F#0 - Slot 2 - Drums only
G0 - Drums + Bass
