play in perfect tune. When you want to bend a not you wiggle the key front to back
and Tilt becomes engaged for that key.
+ Tilt - this outputs continuous values and increases and decreases depending on the tilt of
your foot on the key. In other words if your foot is exerting more pressure on the top
sensor of the key, the value will increase. If you tilt your foot pressure down so more
pressure is on the bottom of the key, the value will decrease.
- Tilt - this outputs continuous values and increases and decreases depending on the tilt of
your foot on the key. This is the inverted version of + Tilt. In other words if your foot is
exerting more pressure on the top sensor of the key, the value will decrease. If you tilt your
foot pressure down so more pressure is on the bottom of the key, the value will increase.
The keys are numbered chromatically left to right as 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11,
12, 13. This source ignores the text that may be printed by the key. A good
example would be to multiply the KeyNum by 10 and apply to MIDI Pan. Then the
left side of the 12 Step will come out the left speaker and the right side of the 12
Step out the right speaker.
+ KeyNum - this will output the number of any key you step on.
- KeyNum - this will output the inverted number of any key you step on.
You can plug an expression pedal into the 3.5mm jack on the rear of the 12 Step.
An adapter is provided for use with ¼” (6.5mm) pedals. You can also supply a 0 -
5V Control Voltage to the tip of this connector.
+ Pedal - this will output the values coming from an expression pedal if you have one
plugged into your 12 Step.
- Pedal - this will output the inverted values coming from an expression pedal if you have
one plugged into your 12 Step.
After selecting your source you can then further modify what values you are sending to your
MIDI parameter by using the math modifiers in the rest of the modline.
gain - this is the first place where you can use math to modify the data signal from the
source. Whatever number is in the gain box is used to multiply the raw value coming from
the source. For example clicking on the gain number box and typing "2" will double
whatever value is received from the controller.
offset - set a number to add to the raw value after it has been multiplied by the gain value.
curve - the result value is entered into the selected lookup table, and used to plot the index
on a chart. There are a number of table options, each which will affect the modulation
differently as it changes value over time.
