What does this do?
This webapp allows you to control your Hismith Servok machine via a Korg nanoKONTROL2 MIDI controller. This allows you to have physical controls for the device rather than just using the app
Why would I do that? The app works
Because touching a screen with sticky hands is annoying! It is also super useful if you want to use the Servok with a VR headset
What are the controls

Slider #1 controls speed. Sliders #2 and #3 control the minimum and maximum stroke location - i.e. max stroke length would be Slider #2 set to minimum and Slider #3 set to maximum.
The knob above Slider #1 controls Smoothness, how "rough" the machine moves back and forth. You should set this initially to the max value then as the session progresses, try lowering it slowly.
Why not build this into XToys?
For various reasons, the Hismith Servok isn't suppported in XToys or buttplug.io, so I had to build this app by reverse-engineering the protocol
Can other people control this app or see what I'm doing?
Similar to XToys, Hismith Control works completely on your computer, no servers involved. There are no logins, and the app does not send usage data or ability to control a device to any server.
What information does this site track?
Vercel Analytics is used to track aggregate visits (aka never identifying any single person, and never recording in any way how the device is used or what buttons are pressed) and performance, and Sentry is used to track errors (aka make sure it actually works correctly and doesn't hurt people!). No personal information is collected.
Can I use a different MIDI controller? I don't have a nanoKONTROL2. Why this one?
Not at the moment, but in the future this will be configurable for any MIDI device. The nanoKONTROL2 was chosen because it is one of the cheapest MIDI devices that can work, you can find it for ~$50 new
What machines does this work on? Does this work with any other model of Hismith machine?
This site currently only works with the Hismith Servok (HISMITH S2). Technically it could be made to work with other models of Hismith devices, but since they already have physical controls, there is no reason to. Other devices also have XToys support which is likely more flexible than this site
Can I use this on my phone? What about a tablet? What browsers?
Yes you can! You can use this app on any laptop/desktop running Chrome or MS Edge, as well as Android devices on Chrome (you may need a USB-C to USB-A adapter or a hub)
Oh my God, thank you so much! Can I buy you a beer for this?
Yes you can! Check the bottom of the main page for information, or if the available options don't work for you, send in Feedback
The device connects but it seems like some or none of the controls do what they should
Apparently some nanoKontrol units (including supposedly brand new ones!) are refurbished units that need to be reset to factory settings. Download the Korg Kontrol Editor app and it will allow you to load the factory default Scene data onto the device.
How do you convert Funscript files to Hismith format?
The Funscript conversion is done via a port of the OFS-FM-script-converter project. Huge thanks for their great work!
