SP404 MK2 & Yamaha Reface Battery Mod

I have tried to provide as much information as possible to help you get on the right track with your battery modification. Yamaha Reface CP solution: power bank glued to the outside I use a USB power bank attached to the outside of the device with a 5V USB-A to 12V DC converter to connect the power bank to the DC input of the Yamaha Reface. When you buy a USB to 12V adapter, make sure that it has the correct polarity (the Yamaha reface needs the positive pole on the center pin and negative on the outside. The “FREEPSLIM3000” 3,000mAh power bank that I have used is great because it can be charged via USB-C at the same time that the USB-A output is used, it automatically turns on when power is needed (when the Yamaha Reface is switched on) and it automatically turns off a few seconds after the device is either disconnected or turned off. Unfortunately, even with hours of online research, I was not able to find any power banks anymore that have these “auto-on” and “auto-off” features, as the current power banks all seem to have manual power buttons and some of them don’t automatically turn on or off which can be a bit annoying. First SP404 MK2: Speaker with built-in power bank I used to have the sampler connected to a Minirig 4 loudspeaker (https://minirigs.co.uk/) via USB-C (for the loudspeaker to provide power to the sampler) and via 3.5 mm jack (for the loudspeaker to play audio from the sampler). To reduce the clutter, I have braided the two cables together with a technique that I found on YouTube for braiding paracords (link below). I love the Minirig loudspeaker as it has a zero-latency analog aux input, while most loudspeakers nowadays have some latency because of their digital signal processing (DSP) chipsets. Another thing I like about the Minirig is that it can be charged via USB-C but also provide power to other devices via the same USB-C connection. To find a loudspeaker that is usable for short transient signals, like drum sounds, it should have less than 30 ms latency on the analog aux input. Don’t even think about using a Bluetooth audio connection, as the latency will generally be unacceptable to use it with instruments.

This way, the battery is thin enough to fit inside the sampler, just behind the battery compartment, without having to cut any plastic away. I have soldered the components of a Ripcord 5V USB-A to 9V DC converter to the USB-A outlet on the logic board of the power bank with a switch in between them that can disconnect one of the contacts (it doesn’t matter if the positive or negative contact is interrupted). In the video, I mention that the switch is between the logic board and the battery but when the switch was at that location, I had to manually turn on the power bank with that tiny button that I talk about in the video. With the switch between the USB-A outlet of the logic board and the 5V to 9V converter, I don’t need to use that little power button. The benefit of this solution over the use of an external power bank or my previous solution is that the USB-C connector remains free to sample from an iPhone or iPad and that I really don't have any cables on the outside of the device apart from my headphones. I have seen a couple of videos and posts from others who have done similar SP404 modifications but they all cut out the battery compartment. I wanted to avoid this in case I ever want to use it with batteries. About USB to 9V/12V converters I decided not to add any Amazon or AliExpress links here but you can find the converter cables by searching for “USB to 12V” or “USB to 9V”. You have to make sure that the converter provides enough current. I first used a cheap no-name converter and noticed that the voltage dropped from 9V to 6V as soon as I turned on the device. With that cheap voltage converter, the sampler would show "low battery" and turn off. I have then upgraded to a Ripcord USB to 9V converter, which doesn't only look more robust with better components, but it also provides a higher amperage output (5V at 3A input and 9V at 1.33A output). If you want to use these adapters without doing any tinkering, make sure that they have the correct polarity and voltage. The Yamaha reface needs 12V with the positive pole on the center pin and negative on the outside. The SP404 MK2 needs 9V with center-negative polarity and positive on the outside.
