I’ll try and answer some of your questions: > [@david-1912](#): > > - 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? > - 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? 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: ![20231124_145902](https://backstage.polyend.com/uploads/default/original/2X/8/8ddb94fe33d6c4aaf2cec8e003b5135c97d9d234.jpeg) > [@david-1912](#): > > 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? 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 > [@david-1912](#): > > 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+. 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. > [@david-1912](#): > > - 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. 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! > [@david-1912](#): > > 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. Technically you can already export stems directly on the Play, so this might already do the trick? --- _[View the full topic](https://backstage.polyend.com/t/introducing-play/6508)._
