Web synths for TouchMe, Biotron, and Playtron when you want more sounds. Own a Playtron? Start with Play.
🎛️ Own a Playtron? Start with Play. Play is Playtronica's online sampler, made for Playtron. Open it in Chrome (Brave and Edge work too), plug in Playtron, and touch to play. The Playtron page has the three-step Quick start. The synths on this page are for TouchMe, for Biotron, and for more sounds.
For TouchMe, open TouchMe online.
ℹ️ The synths at synth.playtronica.com are not made by Playtronica. They are a curated collection of third-party web synths. Some may stop working as browsers change. We try to keep the list up to date but cannot fix the synths themselves. If you find a broken synth, tell us.
Where to find synths
synth.playtronica.com is our curated library of web synths that work with MIDI. Open the site in Chrome, plug in your device, and choose a synth. No installation is required.
How to get sound
- Plug in your device first, then open Chrome. The browser scans for MIDI devices when the page loads. If you open the browser first, you will need to reload the page after plugging in.
- Go to synth.playtronica.com.
- Click Allow on the MIDI permission prompt. The prompt appears once. If you clicked Block by mistake, open the browser settings → Privacy and Security → Site Settings → MIDI → find
synth.playtronica.com→ set to Allow. - Open a synth and check the MIDI dropdown in the top right. Most synths have this menu. Confirm your device is selected.
Recommended synths
🎹 Dots Piano
The best starting point among the web synths. Clean sound, responsive, beautiful interface. Works with both TouchMe and Playtron.
🎸 WebSID Commodore 64
Iconic chiptune sound. Playtron only. Does not work well with TouchMe.
🎵 Viktor NV-1
Powerful synth. Some users report stability issues. Try it. Skip it if it behaves unexpectedly.
Everything else
Any synth without a "Playtron only" label works with both TouchMe and Playtron. Explore — the library has many small gems.
Web MIDI and browser support
The web synths talk to your device through Web MIDI, a browser feature that lets a web page send and receive MIDI. Not every browser supports it. We recommend Chrome. Other Chromium-based browsers (Brave, Edge) also work; Safari and Firefox do not.
| Browser | Works? | Notes |
|---|---|---|
| Chrome | Yes | Recommended |
| Brave | Yes | Chromium-based |
| Edge | Yes | Chromium-based |
| Safari | No | No Web MIDI support |
| Firefox | No | No Web MIDI support |
| Phone and tablet browsers | Not tested | We have not tested Playtronica devices with web synths on phones or tablets. Use mobile apps instead — see Mobile apps. Play plays with the touch screen. |
