i am not using amp switching or the Control Voltage output on my Helix, and I came across something interesting. My preferred tremolo, the EH Super Pulsar has both an expression input and what they call a Tap/CLK input. Below are their descriptions straight from the manual (I've boldfaced the important parts). Please excuse the long read.
EXP Jack â€“ Connect an expression pedal with a TRS plug to this jack to control the following parameters with your foot: RATE, DEPTH, SHAPE, PHASE and VOLUME. Additionally the EXP IN jack can be connected to a CV source using a TS plug; the acceptable control voltage range is 0V to 5V. Some suggested Expression Pedals: EHX Expression Pedal, M-AudioÂ® EX-P, MoogÂ® EP-2 and EP-3, RolandÂ® EV-5 or BossÂ® FV-500L. The polarity of the expression pedalâ€™s plug must have the Sleeve connected to the heel position (usually GND), Ring connected to the toe position and the Tip connected to the wiper. The nominal expression pedal impedance is 10kÎ© though most other values will work fine. Please do not go below 6kÎ© on your expression pedalâ€™s potentiometer impedance.
TAP/CLK IN Jack â€“ This jack accepts up to 3 external footswitches allowing you to set the TAP time and control up to 2 other functions. Additionally, you can set the Super Pulsar to accept clock pulses on the Tip conductor of this jack, instead of switches, so that an external clock sets the Tap time. We recommend powering down Super Pulsar when connecting or disconnecting your external switches to the TAP/CLK IN jack.
EXTERNAL SWITCHES â€“ All external switches that are connected to the TAP/CLK IN jack must be normally open, momentary switches. The tip connection of the TAP/CLK IN jack is hardwired to set Tap time, the tip cannot be re-programmed for other functions. The ring connection of the TAP/CLK IN jack is set from the factory to scroll through the Super Pulsarâ€™s 8 presets plus WYSIWYG mode. Each press and release of a switch connected to the ring will advance and load the next preset. You may also connect a switch that connects to both the tip and ring simultaneously; from the factory, this third switch is set to scroll through the EXP. MODEs. An example of an external footswitch that has 3 switches is the DigitechÂ® FS300. You may also connect a single external footswitch to the tip only, or a dual external footswitch the tip and ring.
PRESET ADVANCE & LOAD FROM EXTERNAL SWITCH: You can advance and load Presets using an external switch. From the factory, the switch connected to the ring performs this function but it may also be assigned to the tip&ring switch. You do not have to enter Preset mode, as described on page 13, to advance and load Presets.
Upon pressing the external switch assigned to Presets, the waveform display will jump to the next preset and load it. The preset LED will remain lit for 2 seconds and then go back to displaying the current waveform. After the 8th preset, the last preset in the waveform display, Super Pulsar loads WYSIWYG mode and then cycles back to the 1st preset.
This all sounds brutally exciting, however very confusing. The Super Pulsar is a VERY deep tremolo with limited foot controls. From the text above, in your understanding, can I use the amp switching/CV capabilities of the Helix to have deeper control of the pulsar?
Thanks for your help.
