This is a configuration instruction for a Roland VH-11/VH-12 HiHat pedal controller. This instruction doesn't cover configuration of a HiHat cymbal. VH-11/12 hardware must be adjusted first according to Roland's instruction manuals. You must have MegaDrum firmware version 20121208 or newer.
1. Set AltIn according to a selected pedal input. For the low impedance input AltIn must be set to No and for the high impedance input AltIn must be set to Yes.
2. Set LevelsAuto to No.
3. Set LowLevel to a minimum (11).
4. Set HiLevel to a maximum (1023).
5. Go to LowLevel and press the pedal to within 5%-10% of fully closed (almost closed). In the top row of the LCD you will read current "raw level" reading. Set LowLevel just below the current "raw level" reading.
6. Go to HiLevel and press the pedal to within 5%-10% of fully open (almost open). In the top row of the LCD you will read current "raw level" reading. Set HiLevel just above the current "raw level" reading.
7. Using Big VU meter make sure MegaDrum properly detects fully closed/fully open positions. If the pedal's Big VU Meter doesn't go all the way left when the pedal is fully closed - raise LowLevel slightly. If the pedal's Big VU Meter doesn't go all the way right when the pedal is fully open - lower HiLevel slightly.
8. If with the rock solid pressure on the pedal somewhere in between fully closed and fully open the pedal's Big VU Meter is not stable you may want to increase RdcLvl.
Adding a 10k-20k resistor between tip and ring may increase the range (smoothness) of the pedal. Using the high impedance input may also increase the pedal's range. After adding a resistor or changing pedal's input you must repeat the steps from this instruction.
