The Garbage Collector v3 is a MIDI to expression converter and MIDI footswitch emulator made by Oscillator Devices. It sits between a MIDI source and pedals that would otherwise need an expression pedal or an external switch plugged into them: it converts MIDI messages into the expression and footswitch signals those pedals accept, so a MIDI controller or MIDI pedal can drive them. It can control up to two effects devices with expression pedal inputs or inputs for external foot switches, such as a tap tempo switch, via MIDI1.
What it does
Many pedals take their expression or external switch control through a simple TRS jack rather than MIDI. The Garbage Collector v3 bridges that gap: MIDI in, expression and footswitch signals out. With two identical TRS outputs, one unit can serve two pedals at once, whether each takes an expression pedal or an external switch input1.
Oscillator Devices notes that "TRS1 and TRS2 of the Garbage Collector v3 have the exact same capabilities," so there is no master and slave arrangement between the two outputs2.
Hardware and availability
The pedal is built into a high-quality anodised aluminum enclosure measuring 69 × 58 × 24 mm, and it is developed and handbuilt by Oscillator Devices in Germany1. It is part of a small range from the same maker that includes the Garbage Collector Mini and the Trash Panda expression splitter.
The maker's shop lists the Garbage Collector v3 at 109,00 EUR as of 21 October 20264.
Firmware
Oscillator Devices publishes firmware updates for the Garbage Collector line. The current version for the Garbage Collector v3 and Mini is 3.5.03.
Questions
What is the Garbage Collector v3 used for?
It is a MIDI to expression converter and MIDI footswitch emulator. A player connects it between a MIDI source and effects pedals that have expression pedal inputs or inputs for external foot switches, such as a tap tempo switch. It can control up to two such devices at once, translating MIDI messages into the expression or switch signals those pedals expect.
Are the two TRS outputs the same?
Yes. Oscillator Devices states that TRS1 and TRS2 of the Garbage Collector v3 have the exact same capabilities, so either output can be used for either connected device without any difference in function.
Where is it made and how do I get one?
Oscillator Devices develops and handbuilds the Garbage Collector v3 in Germany.
