There are many things to consider when buying a controller.

Summary of considerations

In order of importance:

  • Noise level?
  • Price?
  • Available space?
  • User-serviceable parts (buttons/springs/switches)?
  • Game compatibility: Infinitas (60Hz, 120Hz)? LR2? PS2?
  • Turntable deadzone and sensitivity?
  • Swappable 1P / 2P sides
  • Size of turntable? Turntable distance?
  • Turntable height?
  • Turntable material (EMP, vinyl, or other)?
  • USB poll rate (1000Hz vs. 250Hz)?

Buttons

Buttons, springs, and switches

Please refer to parts page for an in-depth discussion on springs, buttons, and switches, especially if you’re trying to figure out what configuration you should buy.

Most controllers will have swappable parts that are compatible with arcade components. Usually, you have the option of buying the controller with your desired parts in it, or you can buy the parts after-market and swap them in.

There are exceptions; e.g., Konami Original Controller (KOC) and Infinitas entry model controller use membrane switches.

Swapping 1P and 2P sides

Most controllers have the ability to change which side the turntable is attached to, so that you can use it as a 1P-side controller or 2P-side controller. There are a handful of controllers that do not have this option, which can be annoying.

Noise level

Most controllers using arcade parts will be fairly loud. Controllers using membrane switches are relatively quiet.

If you live in a shared space, or in a place where noise easily travels to neighbors, you may need to consider getting a controller with membrane switches. It would be very unfortunate if you got a controller only to have your roommates and neighbors complain every time you try to play.

While there are many ways to reduce the noise emitted by a controller, it’s not all that effective.

The most effective method is to build a soundproof box around the controller: 1 2 3

PCB

PCB stands for printed circuit board; in this context, we are talking about how capable the logic board is inside the controller.

Required reading - for this section, you need to understand the difference between digital and analog turntable input:

  • Digital input has three states; neutral, spinning clockwise, and spinning counter-clockwise. There is no sense of velocity, only direction.
  • Analog input works as a numeric value on the X-axis. When the turntable is stationary, the value remains unchanged. When it spins clockwise, the value increases (relative to the angular velocity), and when it spins counter-clockwise, the value decreases (direction can vary - this is just an example). Usually, the values range from 0-255, wrapping around on each end.

Most modern controllers support both, some controllers support only one or the other.

Playstation 2 Compatibility

Not all controllers have a PS2 port. Most controllers made in the 2000’s to 2010’s were made compatible with the PS2, but as of 2022 this has become much less common. If you care about playing CS releases, you’ll want a controller that works with the PS2.

It’s worth noting that DJ DAO does sell a USB To PS2 adapter which alleviates this issue, but it’s not compatible with every controller.

Keyboard mode

Keyboard mode for a controller allows you to use the controller as a keyboard, emulating keystrokes instead of joystick input.

There are some games that aren’t too happy with IIDX controllers operating in joystick mode. Some games would treat an analog turntable as a joystick that is always held down, some games can’t handle more than one controller, and so on; DJMAX is a good example.

Infinitas compatibility

For Infinitas, there are a few things to consider:

  • Older controllers (like DJ DAO controllers before PHOENIXWAN) might have trouble with 120Hz mode of Infinitas. This is due to the fact that 120Hz mode of IIDX requires a more sensitive turntable, resulting in extremely large deadzone or slow scroll speed – see “Turntable sensitivity and deadzone” section below.
  • It is possible to play Infinitas with a digital turntable, but analog is heavily preferred. While the game itself will be playable, you will most likely need a keyboard to scroll through songs, adjust options (SUDDEN+ lane covers), and so on.

It’s better to double check before buying if the controller works well in Infinitas, especially in 120Hz mode.

LR2 (LunaticRave2) compatibility

LR2 only accepts digital turntable input (neutral, spinning clockwise, spinning counter-clockwise).

For some controllers that only provide analog input, such as the Infinitas Premium controller, some users have written a tool to translate the analog input into digital input for LR2. PC_for_LR2 is one such example.

Beatoraja compatibility

Fortunately, beatoraja will happily work with either digital turntable input or analog input, configurable in the options.

beatmania Ultimate Mobile / BlueTooth compatibility

While this is not the most popular feature, some controllers can connect over BlueTooth and allow you to play beatmania Ultimate Mobile.

DJ DAO also sells BE2BT adapter which converts USB controllers to BlueTooth signal.

USB poll rate

Poll rate refers to how often the controller sends input data to the PC. Usually, it’s either 250Hz (4ms between input) or 1000Hz (1ms between input). While 1000Hz is desirable, 250Hz is totally acceptable.

Turntable

Turntable is the most complicated part of a IIDX controller; therefore, there are many aspects to consider.

Turntable distance

Distance between the turntable and button #1 is another important factor, even more so than the size of the turntable. This has a significant impact on how you place your fingers during gameplay. Largely, there are two options:

  1. Arcade distance
  2. KOC (CS) distance

KOC

image source

For reference, above image is a US KOC model.

KOC has the turntable a few centimeters closer to the buttons than the AC dimensions, which makes a huge difference. In general, AC dimensions are more common and preferred by most players.

Size of the turntable

You basically have two choices: get a turntable that is the exact same size as the arcade, or get something that is much smaller. It’s actually easier to play on smaller turntable, mostly due to lighter weight – at least on SP. This is entirely up your preference; the usual recommendation is to go with arcade-size turntable, but you might be constrained by your budget or the space available.

Height of the turntable

Most controllers will have the turntable raised by a couple centimeters to match the arcade dimensions. Notable exception is the KOC which has the turntable sitting much lower.

Turntable deadzone and sensitivity

Turntable deadzone is the distance in which the turntable needs to move in order for any input to register. This applies to both analog and digital turntables. If the deadzone is large, you have to spin the turntable quite a bit before the game recognizes it. If this is too large, it can make the game practically unplayable.

Turntable sensitivity refers to how fast the turntable turns in-game, relative to how much you move the physical turntable. While this doesn’t affect the game play too much, having the right sensitivity is useful in menu navigation and configuring things like SUDDEN+ lane covers.

Some controllers have adjustable deadzone and sensitivity settings.

IMPORTANT: Infinitas in 60Hz mode and 120Hz mode have different expectations when it comes to turntable input. A controller that works totally fine with 60Hz mode may experience significantly larger deadzone and reduced sensitivity when running the game in 120Hz. If you want to run Infinitas at 120Hz, you’ll want to ensure that the controller is known to work well with it. For example, older DJ DAO models (FP7, PEE, RES, RED) will be playable with Infinitas at 120Hz, but you’ll have to move the turntable more so than usual in order for it to register, which can be less than ideal.

Turntable surface material

Controller makers have experimented with various surfaces. There are a handful:

EMP

This is the most common. EMP refers to Empress, version in which this material was first introduced to the arcade cabinets. It looks like this:

EMP sheet

This is a slightly grippy vinyl material that has a bumpy texture. Note that Lightning Model cabinets have a slightly different texture that is more grippy.

Glossy vinyl

This was the default turntable surface for arcade cabinets before Empress. This is just a layer of plastic, so most of the friction comes from your own hands. They are surprisingly playable, unless you have really sweaty hands.

No EMP sheet

Others

KOC uses light plastic material that has a bit of a texture:

DJ DAO’s Phoenixwan uses a silicone material, which some people like (and others dislike):

Lightning Model cabinet and the Infinitas professional model (2022) controllers use a unique grippy material that is textured and slightly rubbery:

Controller recommendations

Please note that not all controllers are covered here, just the popular options. IIDX.org is not affiliated with any controller makers. Page updated on 2022-09-05.

Best option: Phoenixwan+ (newest model)

For most people buying a new controller, DJ DAO Phoenixwan+ (‘plus’) is recommended. Product page

Phoenixwan+

✅ Compatible with Infinitas 60Hz and 120Hz, LR2, beatoraja
✅ Configurable turntable deadzone and sensitivity
✅ Full size turntable, AC distance, swappable sides
⚠️ People are divided on unique turntable surface
⚠️ Relatively high price
❌ No native PS2 support (needs BE2PS adapter)

This is currently the best available option in the market. Its best feature is that turntable parameters are adjustable on the fly, while remaining fully compatible with Infinitas and LR2.

Good alternative: Phoenixwan (older model)

Older models of Phoenixwan is also recommended. Product page

Phoenixwan

✅ Compatible with Infinitas 60Hz and 120Hz, LR2, beatoraja
✅ Configurable turntable deadzone and sensitivity
✅ Full size turntable, AC distance, swappable sides
⚠️ Most models have PS2 support (some later models do NOT, however)
⚠️ People are divided on unique turntable surface
⚠️ Relatively high price, slightly cheaper than Phoenixwan+
❌ Known power supply issues

Older model of Phoenixwan has known issue with its power supply, which usually results in various LEDs dying out over time, with some users experiencing complete failure of the controller.

Cheaper and smaller alternative: DJ DAO FPS

FPS is an older controller by DJ DAO. Product page

FPS

✅ Compatible with Infinitas 60Hz, LR2, beatoraja, PS2
✅ Works mostly well with Infinitas in 120Hz
✅ Adjustable turntable distance, swappable sides
✅ Low price!
❌ Small turntable can be a deal breaker

Official controllers

KOC

KOC is the official Konami controller for Playstation 2, made in the 2000s.

KOC

image source

✅ Compatible with PS2
⚠️ Can work on PC, mostly LR2, but needs an adapter
⚠️ Can be extremely cheap, but finding a good adapter is not cheap
❌ Membrane switches, prone to getting stuck
❌ Digital turntable input only
❌ Flat turntable surface
❌ Turntable height is low - lower than buttons
❌ KOC size turntable, KOC distance

Even though they have been out of production for a long time, the original JKOC is still in active use by many. The controller is still one of the best choices for PS2 CS releases, and works well with LR2 given the right adapter.

Finding a good adapter is the hard part. If you buy a generic PS2 to USB adapter, you will not have a good time. The recommended adapters are Elecom JC-PS101USV and Super Joybox 3.

USKOC, released with North American version of beatmania (2006), is not recommended, as users have reported various issues with using it with an adapter, such as low poll rate and dropped input. US KOCs have a rounded edge around the turntable, while JKOCs have a square edge.

DIY solutions exist to replace the PCB for KOC, or to redo the entire thing except the housing. Here is one example.

Infinitas controllers

Since the launch of Infinitas, Konami launched three different models:

Infinitas premium model (2016)

infinitas premium model

Product page

Infinitas entry model (2021)

entry model

Product page

Infinitas professional model (2022)

entry model

Product page

(All three)
✅ Official controllers, native support for Infinitas
❌ Analog turntable only, not compatible with LR2 out of the box
❌ Not PS2 compatible (but can be used with BE2PS adapter)

(2016 Premium model only)
❌ Tiny turntable
❌ Overpriced and hard to find due to rarity

(2021 Entry model only)
✅ Supports Ultimate Mobile over BlueTooth
❌ Membrane switches, prone to getting stuck

(2022 Professional model only)
✅ Turntable that matches lightning model
⚠️ ... but no turntable resistance adjustment
❌ Overpriced and hard to find due to rarity
❌ Some users reporting LED failures

Entry model (2021) is a revival of the KOC, using membrane switches. The other two use arcade parts. All three of them only support analog turntable input, so if you want to use with LR2, you’ll need a third party tool like PC_for_LR2.

These controllers are good for Infinitas and beatoraja, but not recommended due to low supply and relatively high price.

These would include: FP7, PEE, RES, and RED:

Old dao controllers

FP7 was one of the most common controllers in the past; PEE is its bigger brother. All of these controllers share the same internals, only difference is the size. After the release of 120Hz Infinitas these are no longer recommended.

The main issue is that the turntable has a large deadzone and low sensitivity. This is especially bad with Infinitas in 120Hz mode; while the game is mostly playable, you might have a tough time with scratch-heavy songs. If you mainly play PS2 CS releases or stick to LR2 on the PC, these are fine, however.

FPS is an exception, as the smaller turntable allows it to side step most of the turntable issues, even though it has the same turntable sensor and PCB.

Aftermarket PCBs do exist (e.g., arcin) which practically solves all of the issues with custom firmware, but as of 2022 they are hard to come by.

Other options

YuanCon has many different models of IIDX controllers, but they are made in small batches.
