The PaintAudio MIDI Captain MINI 6 is a MIDI foot controller with six programmable switches, each capable of sending single or multiple MIDI commands every time it is pressed1. It is built to sit on a pedalboard or on the floor in front of a modeler, and RockBoard's PedalPedia describes the MIDI Captain line as more than a controller, calling it a comprehensive musical performance assistant2. The MINI 6 carries that platform into a compact six-switch metal enclosure, with switch functions configured over USB from a computer1.
The controller supports MIDI Program Change (PC), Control Change (CC) and MIDI Note messages, the three command types most modelers, effects units and synths respond to3. It also has USB-MIDI functionality, so it can control DAW software, synthesizers and effects software running on a computer directly over the USB cable1.
What the MIDI Captain MINI 6 does
Each of the six switches can be programmed to fire one or several MIDI commands on a press, which is what lets a single stomp do things like change a preset, toggle a stompbox and bump a CC value at the same time1. The body is a sturdy metal enclosure with a foot switch design built for durability1. Because it speaks plain PC, CC and Note messages, it works with almost any device that has a MIDI IN jack, the same compatibility PaintAudio claims across the MIDI Captain line4.
The USB-MIDI support means the MINI 6 doubles as a computer controller: plug it into a laptop and it will drive DAW software, synthesizers and effects plugins without any extra interface1. For players using a Kemper Player, the smaller MIDI Captain NANO 4 gained bidirectional communication with the Kemper Player over USB in firmware 1.21, retrieving rig names and synchronizing module states, a sign of the direction the platform has been developing5.
Normal Mode and Geek Mode
The MINI 6 has two operating modes, and which one you get is chosen at power-on by holding different keys while switching the unit on; the choice is saved and remembered1.
| Mode | Commands per switch | Total per switch |
|---|---|---|
| Normal Mode | One command for pressing, one for releasing | 2 in total |
| Geek Mode | Up to six commands for pressing, up to six for releasing | 12 in total |
Normal Mode is the simple setup: each switch does one thing when you press it and one thing when you release it1. Geek Mode is where the advanced customization lives, allowing up to six different commands on press and release for a single button1. The same two-mode structure runs through the whole MIDI Captain family, including the DUO and ONE controllers4. The larger MIDI Captain Foot Controller (BLUE) adds a third option, Super Mode, with 18 pre-set pages for mainstream devices including the HX Stomp, FM3, Quad Cortex and Kemper Profiler Player6.
On the NANO 4, PaintAudio notes that in Geek Mode the button indicator lights are limited to the selection mode, with an improvement planned for future versions5. Check the current firmware notes before relying on the LEDs in Geek Mode.
Pro and STD versions
The MINI 6 comes in three finishes, and the finish tells you what is inside1:
- Blue and gold (Pro): built-in wireless module, otherwise identical to each other, differing only in color1
- Black (STD): no built-in wireless module, spray-coated surface, slightly cheaper1
The maker states the wireless module is the main and only functional difference between the STD and Pro versions1. On the STD version you connect by wired MIDI out or standard USB3, and it supports the same mixture of PC, CC and MIDI Note commands as the rest of the line3. Configuration on the STD also works through USB deep-setup, connecting to a PC and loading firmware and config files3.
If you want fully wireless operation, you need a Pro version. The black STD version cannot pair with the wireless MIDI Mate accessory5.
Configuration, pages and expression pedals
Setup is done over USB: connect the MINI 6 to a computer and program each switch's commands, then save them into configuration pages1. The unit stores up to 99 completely different switch function configuration pages, so a page can hold a full setup for one song or one device and be swapped in use1. RockBoard's PedalPedia entry for the MIDI Captain line links an English manual covering the configuration process2.
For expression control, the MINI 6 accepts an external expression pedal, but only one wired for Ring output1.
PaintAudio warns that the controller is only compatible with expression pedals that have Ring output, and that Tip-output pedals such as the Fractal EV1, Boss EXP and Hotone EXP may have compatibility issues1. Check an expression pedal's output wiring before buying.
MINI 6 versus the rest of the MIDI Captain line
The MINI 6 sits in the middle of PaintAudio's controller range by switch count. The MIDI Captain ONE and DUO are the smaller units, the NANO 4 has four switches, and the full-size MIDI Captain and MIDI Captain Foot Controller (BLUE) carry ten keys6. All of them share the Normal and Geek Mode structure, the 99-page limit and the Ring-output expression requirement145.
The NANO 4 differs from the MINI 6 mainly in switch count and in its Kemper Player integration: its KPP firmware package communicates bidirectionally with the Kemper Player over USB, retrieving the rig name and synchronizing module states, with LED lighting that stays consistent with the Kemper5. Firmware 1.21 for the NANO 4 also solved a USB-MIDI latency issue5. The MINI 6's advantage is simply more switches per unit of board space, with the same programming model underneath.

Questions
Can the MIDI Captain MINI 6 run on batteries?
Yes. PaintAudio lists three power options for the MINI 6: a USB cable, a standard pedal power adapter, or battery power. That makes it usable on a board without a power supply, or as a standalone controller for a modeler or synth on the floor.
Which expression pedals work with the MIDI Captain MINI 6?
The MINI 6 is only compatible with expression pedals that have Ring output. PaintAudio warns that Tip-output pedals such as the Fractal EV1, Boss EXP and Hotone EXP may have compatibility issues, so check your expression pedal's wiring before pairing it with the controller.
How do I configure the MIDI Captain MINI 6?
Switch functions are configured by connecting the MINI 6 to a computer over USB. Each of the six switches can be programmed to send single or multiple MIDI commands, and settings are saved across up to 99 configuration pages. PaintAudio also publishes an English manual for the MIDI Captain line.
Does the MIDI Captain MINI 6 have wireless MIDI?
It depends on the version. The blue and gold Pro versions have a built-in wireless module, while the black STD version does not and connects by wired MIDI out or standard USB instead. The STD version is slightly cheaper.
How many pages can the MIDI Captain MINI 6 store?
Up to 99 completely different switch function configuration pages. Each page is a full setup of the six switches, so you can preconfigure different pages for different songs, devices or setups and switch between them in use.
What is the difference between the MINI 6 and the NANO 4?
The MINI 6 has six programmable switches; the NANO 4 is the smaller MIDI Captain controller with HID multi-state cycling. Both share the same platform: Normal and Geek Modes, up to 99 configuration pages, USB-MIDI, and the same Ring-output expression pedal requirement.
