Introducing Play+

That helpful graphic leads me to think it how awesome would it be to have a mode that controls the synth parameters using the pads somehow. Basically to be able to program the entire synth sound using pads. I can think of a number of distinctly different ways to do that. Just giving two examples.

Example 1: Each column per one system parameter. You’d be able to tweak really fast, but not have all the parameters at once without having to switch to another view to get more, nor be very precise about it.

Example 2: Each synth parameter gets just an up button and a down button, press once to change a small amount, hold the button down and let go and it will go up or down over time as you hold it until you let go. This would probably allow you to tweak everything from that mode.

Example 2 sounds more interesting to me just because I’d like to be able to program a synth as easily as possible. And there is of course all the knobs that could be used too. And allowing CC control for each synth parameter so an external controller or on screen daw knobs could be used.

Edit: Came up with another one
Example 3 - Each pad activates tweaking a different synth parameter, but then you have just one knob that you twist afterwards to edit it. Want to edit a different one? Just activate another pad for the different parameter you want. Then turn the knob again for that one. When you switch it shows you on screen which one you selected, so it would be much easier in this one to not accidentally tweak the wrong thing.


That sounds like a wish worth wishing for. Go for it!!

Yeah I’ll add it after more brainstorming and getting my unit, sent my old one off already. I just edited in another idea that I think I like the most.

Gotta say those synths sound incredible! Can’t wait to have a Play(+) with them!!


New to Polyend having ignored the Play when it came out, but the Play+ is really ticking a lot of boxes for me as an almost ideal portable groovebox setup (touch sensitive pads, an internal battery and internal sampling/resampling would have shot it into the stratosphere!)

I’m really hopeful that I can combine this with an iPad Pro M2 for a great portable workflow. But a few of questions:

  1. I think I can plug the Play+ into the iPad Pro 12.9" M2 and it will power the Play+. Can anyone confirm this is the case?

  2. The marketing material and manual mentions multichannel audio streaming over USB. Is this class compliant? I.e. will I be able to use the USB connection to the iPad Pro and see a multi-channel audio device without needing drivers, so that I can record each channel separately into Logic Pro for iPad?

  3. The manual suggests that the multichannel USB audio has channel 10 (tracks 19 & 20) for all 3 synth slots. With channels 11 and 12 currently listed as reserved. This seems like a real shame that the Play+ has 3 synth slots but all three are mixed together on a single stereo pair when streamed over USB. It would be preferable for all three to be separated out on channel 10, 11 and 12 respectively. Can anyone from Polyend confirm that this is in fact an error in the manual, or that this limitation is only for this firmware and intended to be resolved in a later firmware?

  4. Will it be possible to use the USB audio to stream the playback to an iPad, record it in Logic Pro, sampling it and saving into files which can then be copied onto a mounted file device in the Files app? So that the new samples can be transferred onto the Play+ SD card without any kind of unplugging and replugging of the USB and changing of USB mode? If so, this would be a nice workaround for the lack of resampling functionality built in on the Play+.

A few ideas of things I’m really hopeful will be possible in future firmware:

  • I can see that MIDI tracks can have specific chords assigned to a single step, or you can spread a chord out over multiple tracks. It would be nice if the Play had the ability to select multiple tracks then access a “consolidate” function which merges all of the tracks down into a single MIDI track where each step now has a chord that represents what was on the individual tracks.

  • Similarly, it would be nice to be able to select a single track and open the Piano Roll, allowing you to design polyphonic content that then collapses down into a single polyphonic MIDI track when the Piano Roll is closed.

  • It would be great to have onboard resampling so that a Synth slot could have a melody designed on it, then sample that into stereo audio, and move that over to a sample track. Allowing, the synth tracks to be freed up for different synth parts.

Can anyone with their hands on a Play+ or Polyend themselves confirm the answers to my questions please?

I’ll try and answer some of your questions:

I don’t have an iPad Pro M2 but i’ve got the M1 and i think both these questions can be simply answered with the following picture:

I haven’t checked out the manual yet, but if that is the case, then it is a mistake.
There are 28 Channels all in all, here are the actual channel assignments for the Synths.

  • Channel 19 + 20 = Synth 1
  • Channel 21 + 22 = Synth 2
  • Channel 23 + 24 = Synth 3

I personally don’t use Logic, only AUM. But in AUM it is absolutely possible to record each individual channel to files. So i’m pretty certain Logic should allow the same.

However, you can’t currently transfer the saved files back onto the Play+ without removing the SD Card, as there is no USB File Transfer as of yet.

There are a couple similar wishes already, but feel free to create your own Draft wishes entry for something like that, since your specific functionality (consolidate) has not been suggested yet, but sounds like something that could be very practical!

Technically you can already export stems directly on the Play, so this might already do the trick?


Thanks @Sandroid! That’s a massive step forwards in my decision to buy one. Really appreciate you taking the time to check those things for me.


On the loopop video when scrolling through the synth menu you have different parameter sections like oscillator, filter, envelope, lfo, voice and they have an ‘FX’ section but no parameters, does that mean there are FX to be added to the synths in a future update?

Good catch I took a screenshot of the FX part. :thinking:

Nice jam! Have you seen others with the Play+?

It’s good to see Jay Hosking praising the synths! This guy knows a thing or two about this.


Just got my Play+. I saw Loopop video about Patch editing. In my version I can’t see any patch editing voice in the synth menu. Is the loopop machine of the video using an incoming firmware version that we don’t still have?

I just got the play+, there’s no patch editing option. Surely he is using a new firmware. Shame owners can’t still have it. This time I’m likely use the Try at Home formula. Got really pissed off by all these. Enough is enough…

Please be more clear on Play+ firmware status. I can’t buy a machine with an older firmware than a youtube influcer, cmon guys…Patch editing is not available for the synths… I understand it could be a programmed choice to release a new FW in the near future but on the website we read patch editing and so we watched on youtube. But who gets the machine now has not access to this. Have you ever heard of the WOW moment for a product? Yep, this is the opposite. :(.

Valid complaint but Loopop is using the same firmware as you though. However there will be a public beta with a built in patch editor coming tomorrow. We had not shared how to edit synths on the website yet as the new firmware will build it in tomorrow. However if you want to edit synth parameters today put the following file on your sd card’s root directory:

(this editor is very beta but will be cleaned up tomorrow)


Thanks. Really appreciate your support. :slight_smile:
Sorry but I’m a synth addicted and synth mangling as you can Imagine is a one reason we choose to upgrade (I choosed also to keep my original Play).

I’ll also check the download section tomorrow. Thanks.

(My first impressions, to be eventually further inspected in the future: some buggy behaviors may occur on the VIEW (keyboard mode) function with synths. Some notes are like HOLD forever. ).

I also added instructions, not sure what will change from this tom, but it will definitely be easier to use.

Patch Editor Instructions

To use the Patch editor you must add the hidden “.patchedit” file to the root directory of your SD card as pictured. Adding the file as “patchedit” without the “.” will not run the patch editor.

You may need to enable “show hidden files” to properly move the .patchedit file to your SD card.

Show Hidden Files on Mac

  1. Navigate to the SD card Root File
  2. Press Command + Shift + . (the period key). This will show hidden files in the folder.

Show Hidden Files on Windows 11
Click on the Windows ⊞ menu on your taskbar at the bottom of the screen and type folder. Select File Explorer Options from the search results. Select the View tab. Under Hidden files and folders, select Show hidden files, folders, and drives.

*******Important *******

In firmware 1.0 patch edits do not save to a project! If you make changes to a patch or make a new patch and you want the changes saved you must select the “save patch” option. This will save the patch, and overwrite the patch if saved with the same name. These edits could change the patch in existing projects if the “saved as” option is not selected and the patch is not renamed.

Patch Editor is in beta, occasional freezing is possible. We are not asking for bug reports for the patch editor at this time.

Patch Editor has not been optimized for performance, if you experience performance issues with the CPU try running the project without the patch editor.


Was refreshing to see videos on the play+. We as community need to move forward, it’s overwhelming the amount of hype around TE PE133, and not too much from the polyend play +. @Aisjam waiting for your vids on the play+. :hugs:


I removed the .patchedit file as I just posted the new beta firmware to the forum, this also allows for patches to be saved in the project, selecting “save as” will now overwrite the default loaded patch but not change it per project. Play+ Firmware 1.0.1 - Built in Patch Editor - #3 by Mitch Please use this instead as it is a much better experience.


So fast so good. Kudos to the Polyend team. Let us know about an eventual Play+ beta program.

Boah, a demo by @kpmattingly (one of?) the synth patch/preset designers!
