Using Dual Oscillator for accurate harmonies
Tired of using up two synth parts to generate a harmony line? Here's how you can use the Dual Osc synth to get accurate harmonies out of just one synth part. First, a list of the harmonies and the settings. The way the second oscillator's pitch is changed is not through a series of distinct steps, but through a microtonal blending of pitches. This list shows the pitch setting of the second oscillator and the harmony it generates in relation to the main oscillator. To change the pitch, use the "Osc Edit 2" knob.
Osc Edit 2, second Octave in parentheses......................Harmony generated
0...............................................Unison
15 (49)......................................b2nd
21 (50)......................................2nd
25 (52)......................................Minor 3rd
29 (53)......................................Major 3rd
32 (54/55)..................................4th
35 (56)......................................b5th
37 (57)......................................5th
39 (58)......................................b6th
41 (60)......................................6th
43 (61)......................................b7th
45 (62)......................................Maj7th
47 (63)......................................Up One Octave
To use these numbers to generate harmonies, you'll have to record a motion sequence. It's best to use the "Trig Hold" sequence option. Begin recording the sequence, and turn the "Osc Edit 2" knob for the Dual Synth part. You don't have to accurately land on the harmony numbers, but it will be helpful to move it to the number that will pop up most often when you go back to edit it. (Example, record the motion sequence with the edit knob at 25 if there will be more minor 3rd harmonies than anything else). After the motion is recorded, stop playback and enter the "Step Edit" menu, where the recently recorded motion sequence information will be present. You will have to manually edit each harmony number by scrolling through the steps of the pattern. It helps to turn the "keyboard" function off so you can see which step keys are lit for the synth parts, you can then just press those keys knowing there is a note being played at that moment in the sequence. After editing the motion sequence, play the pattern back and adjust the balance between oscillators 1 and 2. You will hear harmonies! Now you have a whole synth part freed up to do whatever with. Enjoy!
EDIT: These numbers will also work in reverse, but the harmony generated will be different if Osc 2 is a LOWER pitch than Osc 1, keep this in mind.
