Tutorial: Bassline /w subtractor synth

I have used Reason version 2.5 for this tutorial. However the subtractor synth is similar in previous version 1 and this tutorial works also with version 3 as well.

The Oscillators-----

Start by activating two (2) oscillators.

1. Adjust phase to maximum on first osc. The value should be 127 .
2. Adjust mix to something around 25.
3. Change phase mode in the middle on both oscillators. (line)

The filter -------

1. Change filter type into low pass 12. (LP 12)
2. Change frequency to 48 and resonance to 68. This filtering makes your bass sound fat and is now also at the bottom end on frequency curve.

The filter envelope --------

Now its' time to shape the filter of your bass sound. We adjust some values of ADSR (Attack, delay, sustain and release)
Values: A=0 D=32 S=0 R=18

The amp envelope -----------

The amp envelope presents how the bass sound will play. For example with Release value R you can control the length of the output note. This happens when key is pressed on your MIDI keyboard or when your bass sequence is playing.

Slide all ASR values to zero. Adjust only decay slider value D into halfway around 63. We just made a short bass sound.

Boosting and cutting the EQ --------

-High freq cut

Now it's time to add some punch to the bottom end. Create an PEQ-2 under your Subtractor. It should be automatically linked to subtractor. Activate both A and B EQ's. Change filter frequency on EQ A to 127 (high frequency, Q value 0 (zero) and gain to -64 (negative -64). This way we cut out most higher frequencies out from the high frequency range.

-Bottom end boost

Boost frequency on bottom end area by adjusting these values on EQ B.
Frequency 19, Q= 64 and Gain 18. This should add some gain around 60-125 Hz. This makes the bass sound more "phat".

That's it, add a matrix or notes into sequencer. Thanks for reading this tutorial.

I found also a very good general sound creation tutorial. It's very heavy with information but there's some good basic stuff.
