The company is best known for PedalSync, its line of audio control chips and modules, and for devices like the NODE 4-loop MIDI pedalboard switcher, the MASTER CONTROL pedalboard MIDI controller and clock, and TEMPODE, the MIDI Clock Injector2.
A maker from Central Oregon
Molten Voltage describes itself as based deep in the Cascade Volcanic Range of Central Oregon, and every product page and manual in its range carries the line "hand built in Oregon, USA"6. The company's founder, Bill, frames the company's digital-control focus as a family trait:
"Digital controls are in my blood. My grandfather, George Devol, invented the first digital programmable robot"
That lineage shows in the product mix. Where most small builders make analog dirt boxes, Molten Voltage's catalog is dominated by MIDI hardware: switchers, clock sources, displays, mappers and synchronizers, plus control chips sold to other builders.
Known for PedalSync and MIDI pedalboard devices
PedalSync is Molten Voltage's brand for audio control chips and modules, positioned as a way to "take your devices to the next level"5. It was offered both as finished products and as components for DIY builders and manufacturers, with datasheets covering chips such as:
- The MV-61 MIDI Pulse chip10
- The MV-59 and MV-59B four-preset modules11
- The LFO Voltage Conversion Module12
- The One Trick Pony MIDI Data Module13
Builders using these modules were permitted to use the PedalSync trademark on their own devices and in advertising1011.
Around the chips sits a range of finished MIDI pedalboard devices. The NODE is a 4-loop MIDI pedalboard audio switcher with what the manual calls "tough, road-ready construction" and a compact design for modular pedalboard layouts214. MASTER CONTROL (in MV-58 and MV-58B versions) is described as a MIDI pedalboard clock and brain1516. MIDI Splitty is a pedalboard MIDI splitter and repeater, and TEMPODE is the MIDI Clock Injector17182. The range also includes SIMI, a modular MIDI display; OSMOSIS, a MIDI mapper and filter; CTL-SYNC, a classic effect MIDI clock synchronizer; CV-SYNC, a programmable control-voltage synchronizer; and TOGGLE, a dynamic and programmable channel switching pedal21920.

Support and repairs
Molten Voltage's manuals give separate contacts for different needs: questions go to questions@MoltenVoltage.com, repairs to Service@MoltenVoltage.com, and legal matters, including trademark questions, to Legal@MoltenVoltage.com226. PedalSync component datasheets also list info@PedalSync.com for support on the chips and modules101213.
One practical note for CONTROL SYNC users: the product page states that Cusack pedals require a 1/4" to RCA cable when used with it22.

Questions
What is PedalSync?
PedalSync is Molten Voltage's line of audio control chips and modules, sold under its own trademark. The company offered chips like the MV-61 MIDI Pulse chip and the MV-59 four-preset module, and permitted builders to use the PedalSync trademark on their own devices and in advertising. It was aimed at DIY builders and manufacturers adding MIDI control to analog effects.
Is the Molten Voltage NODE still made?
No. Molten Voltage's own product page marks the NODE, a 4-loop MIDI pedalboard audio switch, as discontinued. The company's manuals still describe it as a compact, road-ready MIDI switcher, but it is no longer in production.
What does TEMPODE do?
TEMPODE is Molten Voltage's MIDI Clock Injector. It is part of the company's MIDI pedalboard ecosystem, alongside MASTER CONTROL and MIDI Splitty, and is used to get MIDI clock timing into a pedalboard so time-based effects can run in sync.
How do I get a Molten Voltage pedal repaired?
Molten Voltage's manuals direct repair inquiries to Service@MoltenVoltage.com. General questions go to questions@MoltenVoltage.com, and legal matters, including trademark questions, to Legal@MoltenVoltage.com.
